In Coming and Camping Out This Weekend!


by Scott

Our latest container is here. It had a ton of product on it including some items that had been out of stock:




Remember, if there is something out of stock, if you click on the "sign up here to get notified" button on the product page, you'll get an automatic email when it comes back into stock.

Also a reminder that the big Swift Campout is this weekend. A great excuse to get outside and go camping for a night or two. We have some folks out camping this weekend, so stay tuned next week for some photos of our camping adventures.

Dia-Compe Shifters on 11 speeds and Dynasys

by Clint

We'll be carrying these new 11-speed downtube shifters from Dia-Compe.  They're the same as any 10 speed shifter, but with a larger barrel for extra cable pull.  The shifters have a ratcheting mechanism, but they aren't indexed.
Stock photo from Dia-Compe
If you're not into 11 speed stuff, you might still be interested in these shifters.  I was tinkering around the shop yesterday and figured out they have enough pull for 10 speed Shimano dynasys rear derailleurs.  Shimano mountain components are nice for touring.  They're rugged and their cages are long enough to wrap around a large cassette .  
XTR is short for xtreme.
Here's my Pass hunter now.  10 speed XTR rear with downtube shifters.  I figured I'd try out some flat bars too.  They're trendy now.  

Besides 11 and 10 speed mountain, they're also good for 7, 8 and 9 speed Shimano.  I haven't tried it yet, but they might even work with some SRAM stuff.  If you're curious about compatibility, check out this article on Art's Cyclery's blog.  It's a bit technical, but it's thorough and fairly up to date.  I couldn't word it better myself.  
So what do you think?  Could you use these?

Frugal Bike Components

By Chris

Frugality is cool, but hard to practice when you're building up a new frame with new parts. There's nothing wrong with scouring Craigslist and ebay for pre-owned bike parts (I do it), but it takes a lot of time and effort, and you can end up with some pretty worn stuff  Sometimes you want new shiny bits that you know will just work. So I've assembled a list of parts that I'd use to save a little on a new build.

VO Micro Fiber Saddles: Leather saddles look great and, after they're broken in, are probably the most comfortable. In my experience, though, the VO micro-fiber saddles are 95% as comfortable at about half the price and weight. Plus, they don't need to be broke-in, they don't need to be protected from rain, and they don't attract thieves (lots of leather saddles get stolen). We make them in a narrow and a wide version, and next year we'll have models with a smooth cover.

Saddle Loops: Speaking of saddles, these little bolt-on loops allow you to use a saddle bag on almost any saddle. Maybe there is no need for a new saddle if you have an old favorite.

Falcon Thumb Shifters: These are not high end components, but they work surprisingly well, are comfortable to use, and are compatible with almost any 5- to 9-speed derailleurs. They even come with cables. The best part is they cost 12 bucks. No, really, $12 a pair.

Dajia Seatpost: The Grand Cru seatpost is better and offers more setback, but the Dajia seatpost is strong, simple, nicely finished, and comes in many sizes. If that's not enough, it's also really inexpensive for such a well made component.

Deore derailleurs and shifters: We don't sell them, but if you want durable derailleurs for touring, Shimano Deore are a great choice. Deore components have been made for decades and they come in many versions. Several VO staffers look for new-old-stock, or just new, Deore stuff for most of their builds.

Tourist bar: We have 19 models of  handlebars in our store, but for casual around town use the $25 Tourist bars are among my favorites. I've recently used them for a little gravel grinding too. The Milan bar is similar, but with less rise.

VO Quill Stem: These chrome quill stems look like a custom stem and get you bars as high as a Nitto Technomic, yet they cost no more.

VO Specials page stuff: There are usually some great deals here.

VO wheels: VO wheels use our hubs with superb Japanese bearings and high quality rims, yet they are priced lower than many lesser wheels. They are made with a combination of hand and machine building to keep cost low without compromising quality.

Paselas tires: The Japanese Pasela tires may not be the cheapest option, but the great ride quality, durability, and classic looks makes them a bargain.

Tektro CR720 brakes: We love these canti-brakes. They are great stoppers, good looking, easy to set up, and only $29/wheel.

VO Alloy Headsets: Sealed bearing headsets are great, but folks have been riding with regular ball bearing headsets for over 100 years. Keep them adjusted and greased and they will last a very very long time. You can even replace the bearings for a couple of dollars.

Alloys of Cycling

by Clint

Photo credit: Mombat, 1991 Mountain bike action

It's been a while since I've cracked a materials textbook, but we get questions about these things every once in a while. Here are some of the basics for alloys you're going to see in the bike world. I'm going to keep it as non-engineer-y as possible, so don't worry about it when I say things like weight instead of mass.

Let's start with properties. Some important properties for materials on your bike are strength, weight, corrosion resistance, cost, and manufacturability.

Within the strength discussion there is yield strength, fatigue, elasticity, and impact resistance. Yield strength describes how much stress you can put on a material before it permanently bends. This is important for a single large impact, like a drop on a mountain bike. Fatigue is important if you do that drop 10,000 times. Little forces create little bits of damage that build up over time.

Elasticity as a property is pretty straight forward so I'll just talk about the marketing behind it. Skinny tires are out. Tires are getting bigger. Comfort is the new speed. I appreciate that this style of riding is trending more, but I think words like compliance are silly. Stiff carbon frames are too uncomfortable, so we need to make them more flexible. We need it to sound intentional. We'll call it compliance!

Impact resistance is especially important in a touring bike. A high end frame may be strong to ride, but if the tubes are thin, they'll be prone to denting. There's more discussion on this sort of stuff in an older blog post.

Corrosion is important depending on where you live. Salt from water or roads is nasty stuff for your bike. Rust on steel and pitting in aluminum are pretty common forms of corrosion for bikes. Most components are going to have some form of corrosion resistance. Paint, coatings, or material properties are the most common means of protection. Best to keep an eye on corrosion, as it can lead to failure if it's bad enough.

Not much to talk about in terms of cost: some materials cost more than others. Make sure you're spending your money for the right reasons.

Manufacturability is less important to the customer, but just know that some materials are easier to work with than others. Some are easier to machine (cut into a shape), some are easier to weld. For example, stainless steel and titanium are more difficult to weld than cromoly. So even if the material itself is stronger, there's a chance (if the welder is inexperienced) that the connections can be weaker.

On to materials! Steel is the most important alloy of cycling. I'm not here to discuss the differences between different annealing/hardening methods or the differences between Reynolds and Columbus tubing, but I'll discuss basic properties. Steel is easy to weld and easy to braze. It's the most elastic of the materials discussed in this post, so it'll stretch more before it breaks.

4130 Chromoly is a useful steel in the bike world. It's strong, light, and can be worked into all sorts of shapes. As you may have guessed, this is what our frames are made out of.

Aluminum is a light and rigid, but brittle. It's good for weight savings but usually not the strongest option. It's also easy to machine, but harder to weld. Aluminum is also fairly corrosion resistant, although over time, pitting is possible. Because of its brittle nature, failure is more catastrophic than steel (meaning it will break all at once instead of bending like steel). Additionally, aluminum frames are thinner than steel frames, so they're easier to dent. There are four different types of aluminum alloys common to cycling: 2000 series, 6000 series, 7000 series, and scandium.

  • 2000 series aluminum is easy to machine, but hard to weld. Copper is the main alloying metal. It's not all that common in cycling.
  • 6000 series aluminum is probably the most common, easy to weld, generally good all around. Magnesium and silicon are the main alloying metals. Most of our aluminum components are 6061, (stems, crank arms, etc.).
  • 7000 series aluminum is generally the strongest, but can be expensive and brittle. Zinc is the primary alloying element. Our chainrings are made out of 7075 aluminum.
  • You'll occasionally see scandium frames in the bike world, which refers to scandium aluminum alloy. It's light and strong, but it's prone to failure so is less common these days.
Stainless steel is used where the strength of steel is needed, but other means of corrosion resistance are insufficient. We make our racks out of stainless steel so they'll last for the long haul. This means our connection points (welds not brazes) won't be as pretty, but we think it's worth it.

Titanium is an exciting material in the cycling world. It's stronger than steel and has natural corrosion resistance, though it has a few drawbacks. It's expensive and tends to be more brittle than steel  There are two different titanium alloys commonly used in the cycling world, 3Al-2.5V and 6Al-4V. The numbers refer to the ratios of aluminum and vanadium in the alloy.  3/2.5 is standard as far as titanium goes; 6/4 is the more exotic of the two, lighter and stronger than 3/2.5, but harder to work with. The points discussed in manufacturability apply here. It's generally used sparingly in places where strength and weight savings are more important. One exception is the Litespeed Tellico. It's famous for being Litespeed's first entirely 6/4 frame. And yes, I love old Litespeeds.

Material knowledge is important for a cyclist, but ultimately you should trust the manufacturer's judgement in material selection. Chances are they have the knowledge, experience, and testing capability to decide what's best for their frame designs.

Comprehensible, Incomprehensive list of BB Standards

by Clint


These days, there are practically more bottom bracket standards than there are bicycles.  As a follow up to Chris's post, I'm going to shed light on a few new technologies beyond the standard square taper.  Unlike Chris's post, this post isn't meant to be useful in any way, shape, or form.

Modern bottom brackets are classified in three different ways: Shell interface, shell width, and spline.  Shell interface and width are dependent on your frame while spline is dependent on your crank.  All of our frames are English threaded.  The Campeur, Pass Hunter, Polyvalent, and Camargue all use the standard road shell width of 68mm.  The Piolet uses a 73mm shell to allow for larger tire clearances and mountain components.  All of our cranks are JIS square tapered.

Besides the standard English threading, and other nationality based threading patterns (discussed in the previous post), other shell interfaces include:

-336EVO - 46mm diameter, 87mm width
-BB30 - 42mm diameter shell
-BB86 - 41mm diameter shell, road bikes
-BB89.5 - 41mm diameter shell, 89.5mm width
-BB90 - Trek, bearing cartridges sit directly in frame
-BB92 - 41mm diameter shell, mountain bikes
-BB95 - Trek, bearing cartridges sit directly in frame
-BB107 - 41mm diameter shell, 107mm width
-BB121 - 41mm diameter shell, fat bikes
-BBright Direct fit - Cervelo, offset from the center plane, 79mm wide, 42mm diameter
-BBright Press fit - Cervelo, offset from the center plane, 79mm wide, 46mm diameter
-PF30 - 46mm diameter shell
-PF41 -  41mm diameter shell

Please note: in the BB# naming system, the # can refer to the spindle diameter, shell diameter, or shell width.

All of these are threadless, but that doesn't mean they're compatible with our threadless bottom bracket.  Most are wider shells for larger spindles and bigger bearings.  Threadless shells have been around for a while.  Merlin frames had their own threadless shell.

You can try the new T47 standard if you want the advantages of a large diameter, but without the creaking and noise associated with threadless shells.  According to press releases, the T47 should "yield a much higher interface success rate."

Bottom bracket shell widths range anywhere from 61 to 132mm.  The wider stuff is generally for fatbikes and larger tire clearances.  Getting a drivetrain to clear those large tires has been a challenge in the bike industry lately.  The solution is usually a combination of thiner chainstay, wider bottom bracket, wider rear, and larger Q factor.

Last is the spindle interface.  A few of these include:

-386 EVO - like BB30 but requires a longer spindle
-BB30/PF30 - 30mm diameter spindle
-BBright - crank must accomodate offset
-Campagnolo Power Torque - outdated Campy system
-Campagnolo Ultra Torque - current Campy system
-FSA Mega Exo - downhill, extra bearings, there are several versions of this system
-Hive Polygon - it's not a polygon, it's a rounded triangle
-ISIS - it came out before the other ISIS went mainstream
-RaceFace Cinch 30mm - oversize spindle
-Rotor 3D+ - oversize spindle
-Shimano Hollowtech II - current Shimano standard
-Shimano Octalink VI - no longer used for cranks, but I think you can still get bottom brackets
-Shimano Octalink V2 - same deal, replaced by Hollowtech
-TruVativ GXP - SRAM for 2 piece cranks
-TruVativ Howitzer - oversized for downhill
-TruVativ HammerSchmidt - HammerSchmidt was revolutionary
-TruVativ Power Spline - functionally similar to a square taper but with a proprietary spline
-Zipp Vuma - I think this is some kind of aerobics class

The ones you should know (besides square taper) are Shimano Hollowtech II and Campagnolo Ultra Torque.  Hollowtech II is compatible with some other stuff.  For example, newer models of the FSA Gossamer crank can use a Shimano Ultegra Hollowtech II bottom bracket.  I have this on my cross bike.  Campagnolo Ultra Torque is certainly less common (if not exclusive to Campagnolo cranks), but new Campy is still cool.  Everything else is garbage.

Some other bottom brackets standards and technologies not discussed in this post include
-BB7 - these are brakes
-BB8 - this is a robot
-BMX - designed for impact and stunts
-CF69 - I made this up
-Eccentric - they're a bit off center
-Freewheel - featured on some old Schwinns
-Tandem - usually eccentric

Some of the new bottom brackets have their advantages.  Some introduce new problems.  Most are designed for stiffness.  Maybe someday we'll change, but the square tapers still work.

Bottom Bracket Basics Revisited


By Chris,

We get an e-mail with bottom bracket questions almost every day; that's the way it's been since I started VO. I wrote the original BB Basics post in 2009 in an effort to rein in the confusion and to relieve Scott's e-mail load. Here it is again, with a couple of minor updates. This post covers only square taper BBs that fit our frames. Clint will write about some of the post retro-grouch BB standards later this week:


Lately my in-box has been overflowing with questions about bottom brackets. So I thought I'd write this simple guide that I can later forward to those seeking advice. Of course, this is only about square taper cranks and BBs.


What spindle length?

I often get questions such as, "What is the proper BB spindle length for a 1954 Urago mixte?" Come on; I'm not Sheldon Brown! In any case, the length of your BB spindle is determined largely by the model of crank you use, not by the type of bike. Every crank's manufacturer recommends a BB type and length. Of course, if the crank is long out of production, a lengthy conversation with Google may be required to find the specification.

As with anything, it's not quite that simple. There are a couple of other factors that can influence spindle length. If your bike has particularly wide chain stays, such as those on a mountain bike or a loaded tourer, a longer spindle may be require in order to ensure that the crank arms clear the chain stays. Often, the only way to be sure is to install the crank and see if the  BB works. If not, measure the interference or gap and buy a second BB. Unfortunately BBs that have been installed are not returnable, but there is always E-bay. The other factor that might influence spindle length is BB spindle taper.

Symmetrical VS non-symmetrical spindles
Some BB are non-symmetrical: the spindle is longer on the drive side. Today it can be hard to find the proper non-symmetrical spindle BB for old cranks. One solution is to use BB spacers to push the BB over a few mm, effectively making a non-symmetrical BB. Or you can just get a slightly wider symmetrical BB and not worry about it.

Spindle taper
The vast majority of square taper cranks uses either an ISO or a JIS taper. Basically, the angle of these two types is almost identical. It's just that a different portion of the taper is used, as I've tried to show in my sketch.



For the most part, only Italian frames use ISO today. The rest of the world uses JIS. But there are exceptions, such as the top-of-the-line Sugino track cranks; all other Sugino cranks are JIS. Some older cranks from Stronglight, TA, and other European companies also used ISO tapers. Only Ofmega and Avocet, of the major manufacturers, used a proprietary taper.

It's usually possible to fit an ISO crank on a JIS BB. The only caveat is that the crank will be 3-4mm wider than if an ISO BB was used, so pick a slightly narrower spindle and tighten the crank bolts securely.

I don't recommend using a JIS crank on an ISO spindle because the crank may bottom out, thus permanently ruining the taper. If, however, you are careful, it will work with some combinations.

One of the problems with this whole idea is that manufacturers sometimes take a casual attitude toward  following one standard or the other.  I have seen TA cranks, for example, that appear to be ISO and an identical crank that's JIS, or perhaps something in between.

BB threading
Let us begin with the French standard because this is, after all, Velo Orange. The French decided that BB shells should be 68mm wide, threading should be35mm x 1mm, and both cups should tighten to the right. Simple and effective! Of course VO makes French BBs.

The Swiss, improved the French standard by reversing the thread on the drive side. This became the Swiss standard and was adopted not only by Swiss manufacturers but also by a few French companies, notably Motobecane. (Motobecane also used French threading on occasion and later switched to British threading; good luck.)  The BB shell is 68mm wide and also threaded 35mm X 1mm; but the left cup tightens to the right and the right to the left.

The reason for this improved standard was that the spinning of the crank was thought to loosen the right-hand thread non-drive BB cups. After a few decades, the Swiss noticed that French cyclists, in fact, were not stopping every few miles to tighten their cups. And so the standard was quietly abandoned. The only Swiss threaded BBs made today are the super expensive Phil Wood units. But VO does have a threadless BB that is a less expensive alternative.

The French standard was also eventually abandoned and, to the everlasting annoyance of the French and of francophiles everywhere, the British (or ISO) standard became the world standard. If your classic frame was made in America, Japan, Taiwan, Germany, or Britain, it almost certainly accepts a British threaded BB. This standard is 1.375" X 24 tpi with the left cup tightening to the right and the right to the left; the BB shell is 68mm wide. Most VO BBs are British thread.

Not leaving well enough alone, some British manufacturers, particularly Raleigh, came up with other standards that are outside of my understanding, as did some old American manufacturers.

Finally the Italians, who we reluctantly acknowledge do know something about bicycles, if only the racing sort, blithely ignored everyone else and stuck to their own standard. The Italian BB shell is 70mm wide and has 36 mm X 24 tpi threading; both cups tighten to the right. VO makes Italian threaded BBs in sizes to fit our cranks.

Speaking of Italian BBs, I should note again that at least one company, Ofmega, used there own propitiatory axle taper. They also made Avocet cranks which use the same bizarre standard. A regular taper won't work. I know this since I destroyed an Ofmega crank on my old race bike by trying it. Find a BB on E-bay if you have one of these.

Damaged BB shells
If the threads on your frame's BB shell are cross threaded, stripped, or otherwise damaged you can use the VO Threadless BB that I mentioned earlier. Taper is JIS. We have used these on British, French, and Swiss BB shells and they work perfectly. Customers report that they also work in Raleigh frames with a 71mm wide BB shell. These BB's won't work on mountain bikes, as their standard width (73mm) is too wide for the shell to expand. They also do not work on Italian threaded BB shells because those have a wider ID.

So there you have it, a gross oversimplification of BB standards that should, nonetheless, provide sufficient information to fit 99% of traditional frames with BBs.

If you need help installing BBs, please read the excellent BB section at the Park Tools site.

Special Deals and Closed for Memorial Day

By Chris

http://www.bikecafe-store.com/
There's lots of great new stuff on the VO specials page; some is 50% off! I'm on this inventory adjustment rampage lately. We have two containers of parts on the way and I'm trying to sort of re-boot inventory levels. The goal is to run out of stuff less often and also not to have too much on hand, shouldn't be hard.

We'll be closed Monday for the Memorial Day holiday. Have a safe and enjoyable long weekend! Maybe strap the grill to the porteur rack and head to the park or beach.

Here are a couple Pass Hunter Discs built up with Dajia Far Bars for your enjoyment.

Raw Camargue PTB (Porteur Trail Bike)

Neo-retro PTB (porteur trail bike) build.
The PTB was built using a frame damaged during Casey's single track testing. Almost every part was a blemished, prototype, or returned part from our "yard sale" bin. The media blasting and clear powder coating was done by a local shop and looks great. But clear finishes aren't durable so the frame will develop surface rust soon; we'll just call it "patina".

A very complete build list:
Raw finish shows off neat brazing and welding typical of VO frames.
Prototype Herse-style stem that we won't be making because it's too heavy and expensive, but it does look so cool.
Low gearing for trails or city and Sabot pedals so we can ride in any shoes.
Hammered bell.
Distressed head badge
Derek runs out for pizza on the new shop bike.
Obligatory wine pic. This is VO, after all.
Shop/trail velo? Town and country? PTB? Surf and turf?
I really love this build. It could be one bike for everything. It's also great that it's easy to add fenders for winter. Anyone else ride a town and trail bike?

Raw Camargue Shredeur, MTB History Recreated

By Chris
Photos by Igor

Long before the boys in Marin county were inventing mountain bikes, French cyclists were riding and racing city bikes and porteur bikes on a motocross track and in the woods near Paris. Check out the antics of the VĂ©lo Cross Club de Paris in the video below.
So when we needed a theme for our new raw framed shop bike, we decided to imagine what mountain bikes would look like if they had descended from those early French velos.
Here is what we came up with. It's based on a prototype Camargue. We'll post some build pics tomorrow. The first ride photos are below.

DIY

by Scott

I'm not one of those natural tinkerers. I didn't take apart radios as a kid or try to figure out how a toaster worked.  My big achievement in the past was taking apart my espresso machine to put a new gasket in the steam wand. But I have always enjoyed working on bikes and taking care of my bikes.
                                 
My first job was working for a bike shop in suburban Vancouver. The owner had cycled across Canada and loved touring bikes, but was also smart enough to realize that in Vancouver in the mid to late 80's, mountain bikes paid the bills. Back then it was still cup and cone bottom brackets, 1 inch threaded headsets and thumb shifter's. All the bikes we sold were built up by us. We'd have 5 or 6 of us on hand on the busy summer days, each a combination bike mechanic and sales person. We'd get an order from the front of the shop and we'd build the bikes up, taking the BB apart and applying boat trailer grease instead of the Vaseline looking grease that the cups came with. Same thing with the headset, new grease packed in there and everything adjusted by hand, then handed over to the boss, who'd give it a whirl on the stand to check our work over, while talking to the new customer. After work, we'd hang out, working on our own bikes, rebuilding our bottom brackets or regreasing cables or using the shop degreaser to clean our chains and cassettes. All of us rode to work, in all weather, which in Vancouver meant rain at least one day a week. Throw in going off road on the weekends or week night rides in the winter, and the bikes took a lot of abuse. But it was fun to work away on my bike. We had good stands to work with, all the right tools to make it go easier and faster, plus my boss in the corner in case we ran into any trouble.
                         
 (stolen from mtbr forum)
When I built up my Piolet last year, it certainly wasn't the same as when I built up my first MTB, a Rocky Mountain Hammer, back in 1988. The hubs are all sealed cartridge now, the headset and bottom bracket use cartridge bearings. I've been riding that Piolet as much as time and the weather here in Maryland will allow this winter. And yet, I'm not finding myself wishing that I could sit in the garage/shop and whittle away some hours repacking things. I've gotten older and have less spare time/free time to be able to look after that sort of thing now. Having cartridge bearings for the BB and headset means that I'll get the same level of performance now and in 5 years.

                                        (Scott's home made pen and pencil holder)

I'd say a good number of our customers are do it yourself'ers when it comes to bikes. Are you a DIY person when it comes to all things around the house and yard or are you more of a one specialty DIY person?

On another subject, should you want to install some nice, but inexpensive parts, then check what we've just added to the VO Specials Page.

Two Piolet Builds Plus a Proto 1x

by Igor


Our friends from Gravel and Grind in Frederick, MD built up a Piolet for a friend who works on a commercial tree farm. Be sure to check G&G out on instagram or stop in for a delicious pick-me-up.

"It's a big and rugged place with lots of rocks and pot holes where old trees were. She started riding her bike there as a way to stay warm in the winter when going to check on trees. She had an old ratty aluminum mountain bike, but her rad boss just approved this purchase. Mainly what she does is ride around with it, pruning stuff (hence the mad max saw scabbard which it'll have next week), inventorying stuff, tagging trees and things like that. She'll occasionally use it for real mountain biking and maybe some bike packing.


I built it with 9 speed thumbies set up friction because she hates maintenance, TRP brakes, 2.5 Maxxis DH tires for durability and mud clearance, and low gearing because the going there is rough and slow."


The Radavist put together a great photoset of a Piolet with a titanium cockpit, meaty tires, Klamper brakes, and double Mojave Cages.




Lastly, keen VO observers may have seen a silver 1x crankset on a previous blog post. We received a new sample which is beefier, smoother spinning, and has much better chain retention (thanks to a narrow-wide ring). Sorry, no full drive side photos; that's due to the VO Skunkworks division' rules. The red bottom bracket cups are growing on me and give a really nice contrast on the blue frame. What do you think?
