Road bikes converted to flat bars are gaining a lot of popularity in urban environments. The combination of an upright position and ease of control makes this type of build a great option for those riders who mainly ride in the city and want to be a bit more comfortable on group rides.
This Pass Hunter Disc setup is our interpretation of an urban day-tripper to conquer any road condition that may crop up. We laced up some 650b wheels to be the basis of our build. By using the smaller wheelsize, we could increase the cushion of air the bike rides on. We selected the WTB 47mm Horizon tires, which end up being about the same circumference of a narrow-tired 700c wheel. Cobbles and potholes are vanquished, and hopping on and off curbs poses no threat.
Clint scrounged up some super clean Campagnolo downtube shifters which we mated to our shifter mounts to make the dangler and pusher move around.
The 7700-series Dura-Ace derailleur was never designed to work with a 36t cassette, so we used a Wolftooth Roadlink to extend the range of the cage. Shifting is fine, but not quite as fast as pairing the same derailleur with a 11-28t cassette. Then again, you're not shifting all that much around town, anyway.
You may have seen this constructeur-style stem that we were thinking about re-making on a previous blog post. After a couple samples, it ended up being far too heavy and expensive. But it looks really cool.
I'm thinking of making the "Bike Build Ideas" a more regular addition to our blog. We have several demo, sample, and show frames around that we look forward to building and re-building to give our readers some ideas for their own projects.
Complete build list:
- Pass Hunter Disc Frameset
- Postino Handlebar
- Grand Cru Disc Touring Hubs (Front and Rear) laced to Diagonale Rims, DT Swiss double-butted spokes, brass nipples
- Velox Rim Tape
- WTB Horizon tires, 650x47mm
- Grand Cru 1 1/8" Headset, Mirror Finish
- Grand Cru 50.4 bcd Crankset
- 118mm English Threaded Bottom Bracket
- Grand Cru Sabot Pedals
- 7700 Dura-Ace derailleurs
- White Brake and Shift Housing
- Avid BB7 Calipers
- Grand Cru Regular Pull Brake Levers
- Campagnolo Downtube shifters (one mounted on downtube)
- Downtube Shifter Thumb Mounts
- One Shimano Downtube cable stop
- Black Cork Blend Grips
- Grand Cru Seatpost (pictured above is the MK1 model)
- Microfiber Touring Saddle, Narrow
Awesome post! I really like seeing more practical builds that deviate from racing roots without looking sluggish!
ReplyDeleteHow long have you had your urban?
ReplyDeleteI second the kudos. Love to see more posts like this.
ReplyDeleteThat's a 7700-series Dura Ace derailleur.
ReplyDeleteDmitri, you're correct!

Just curious, but what was the reasoning behind putting the front shifter on the downtube instead of the handlebar?
ReplyDeleteI think you mean Dura Ace 7600 on the parts list, not 7400.
ReplyDeleteRad bike overall
Pusher? Dangler? Are you reading _the website_?
ReplyDelete@Blood Sausage, with the 46t chainring and wide range cassette, I don't have to shift the front rings very often around town. Just having a single downtube shifter makes the bike a bit lighter, a bit simpler, and a bit weirder.
ReplyDelete@Anon, thanks for the catch.
@Eric, definitely not. Sometimes. Yes.
@Anon DA 7600 was a track group of which I'm not seeing on this build.
ReplyDeleteI think there is a market for stems like the prototype. I would buy one despite the weight and even if it's expensive ---if it were available in 120-130mm lengths. For some riders with longer stems, rigidity is more important than weight. Cinelli used to market an odd looking CNC'd girder style stem about 20 years ago when everyone started selling CNC parts. This one is far more attractive since it replicates the style of the old constructeur stems. Please reconsider offering this stem. It would be great for stylish retro style road bikes, great for "gravel" or "allroad" or "adventure" bikes, great for mountain bikes, great for track bikes, and would not look out of place even on the most current carbon fiber technological wonders.
ReplyDeleteNice build. That internal brake routing gets me every time. It's so clean looking! In my humble opinion, this bike would look even more awesome with some shiny fenders. Things look real tight between the tire and fork blades on picture 2. Do you think you could cram some zeppelins in there?
ReplyDeleteCould you size down to a 42c tire to accommodate the fenders without getting the cranks dangerously low?
Scott S,
ReplyDeleteThe tires currently measure out to 44mm, so Zeppelins would actually fit with a bit of dimpling.

ReplyDeleteHow much clearance does the frame have with the Horizons? Any more pictures of it?
ReplyDeleteI have 650b x 42 Schwalbe Marathon Supremes on my Pass Hunter Disc and they fit great with fenders. So did the 650b Grand Bois Hetres
Delete@Anonymous
ReplyDeleteThey fit, but no room for fenders! The future Polyvalent will be better suited for the Horizons.
Quick question... the Pass Hunter Disc page says it can't run Avid brakes, yet you're clearly running them here. What is the official stance on the BB7s?
ReplyDeleteJust want to know so I don't void any warranty.
@Jeffrey Jay
ReplyDeleteNext run will work with BB7s!
