Then we could have the best of both worlds.

I tired them in a 185mm a few years ago, but returned them due to the flex of the arms and rings. The rings would always rub on the front dérailleur. I've never seen a crank flex so much. I'm no masher either, just tall.... about 165 lbs.<BR/><BR/> I went to a TA Zephyr, and it's rock solid...... Too bad they don't make it anymore.<BR/><BR/> I'm going to need a new crank soon... and would like a similar tread(Q). I've read varying reports of the Sugino XD arms as far as what their tread is.... anywhere from 160 to 169. The Zehpyr's are about 156mm for the triple.<BR/><BR/> Has anyone measured the XD triple arms with a 110 BB? I see the Alpina double is listed here in VO as 160mm with a 110BB, but are the XD arms the same ?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-24415034.post-28482783154140019762008-08-09T03:27:00.000-04:002008-08-09T03:27:00.000-04:00I would suggest either 86BCD or the Stronglight 49...I would suggest either 86BCD or the Stronglight 49D which you list as 50.4BCD but is really different since the large chainwheel attaches directly to the crank arm.<BR/><BR/>I see an advantage for the 86BCD since it would not require as strong a large chain wheel. Also, since there currently isn't a crank set with this BCD in production, you could also sell some chainrings.<BR/><BR/>With the 49D style crank, the largest is what actually determines the BCD for the inner chainrings. This has both advantages and disadvantages. You can have options for different BCDs for the inner chainwheels. This means more different parts but the only difference is going to be the location of 5 holes. And, if you start with a large BCD, the middle chainring is going to have to also have a smaller BCD for the granny chainring -- this probably isn't going to be just a matter of drilling holes.<BR/><BR/>It could also be possible to simply do both by offering a 49D style crank set along with a spider for 86BCD chainrings. Would this be significantly heaver than making a one piece 86BCD crank.<BR/><BR/>If you went with the spider idea, you could offer other BCD spiders as well -- at least the popular 110/74. Perhaps a solution to the large number of different sizes of chainrings.<BR/><BR/>Also an other question. Will you offer the old style of crank arms that look like a Stronglight 99 or 49D? They do look better on old bikes.<BR/><BR/>Old bikes also look better with the separate spider and the 49D style with a spider would accomplish this.JRThttps://www.blogger.com/profile/15647792750147789942noreply@blogger.comtag:blogger.com,1999:blog-24415034.post-39995236704664085292008-07-28T03:40:00.000-04:002008-07-28T03:40:00.000-04:00PS.

Late in the season (or when I'm not lugging the trailer and gear) I swap the rings to a 32/46 or a 32/48. I've run it as a 'compact' 34/50 as well, but prefer the low end here in VT. I'm running a Campy 10 sp 13-29 in the rear. I spent the $$ on a bunch of different rings - so I have options to tune the bike to the ride... rather than have a standard 'triple' and never really use the high end, and get frustrated with the low end.<BR/><BR/>I really like the low Q - and notice it when switching to my old (wife's) Ultegra triple, or my MTB, or my cargo bike.<BR/><BR/>-Mikebmikehttps://www.blogger.com/profile/14690285578204158345noreply@blogger.comtag:blogger.com,1999:blog-24415034.post-22417299724383507872008-04-10T17:20:00.000-04:002008-04-10T17:20:00.000-04:00I would urge that you produce the 50.4mm crank-- I...I would urge that you produce the 50.4mm crank-- I shudder to think of life without my collection of TA Pro Vis 185mm crankarms!

A sample crank is already speeding toward our secret factory in Taiwan. I sent a Nervar crank because it has close the ideal geometry, low Q factor with a bit more room between the arm and the big chainring. Of course we will change the fluting and the dimensions of the arms.<BR/><BR/>Regarding Sugino Alpina cranksets. I learned that there are four quality levels of chain rings available on Alpina cranks. The very best are CNC machined, pinned, ramped, and close to TA quality.

As far as having rings made, bolt pattern choice does not affect the cost per ring to any great extent. Cranks can outlast several sets of rings, so there have to be lots of cranksets out there that would be fine for another couple of decades if there were rings available.

The Ultegra Octalink b/b is the one I like most of all, and mine is still as smooth as the day I bought it. The key I've found with Octalink is to carefully line up the spline interface between the crank and b/b before tightening it up, and after you've ride on it a while check the tightness of the unit from time to time. The Dura Ace Octalink b/b has adjustment rings on both sides and many users reported frustration with that one even if they were a competent wrencher. All in all I'm happiest with good old square taper b/b's.<BR/>I've rode friends outboard bearing b/b's, but I can't tell any differences - then again I'm a light rider.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-24415034.post-60042534204513968482008-04-07T16:47:00.000-04:002008-04-07T16:47:00.000-04:00Somebody please explain to me what advantage a 130...Somebody please explain to me what advantage a 130/74 double would have over a 110/74 double?
