Dura Ace TT crank(5 posts)

Dura Ace TT crankDuane Gran

A couple of times I have seen a TT specific Dura Ace crank in photos and at events. About the only way I can describe it is to say that the chainring is more solid looking and has the "Dura Ace" lettering on the ring. It looks a little larger in circumfrence, so I infer that it has more than 53 teeth.

Has anyone had experience or info on this? I looked at the Shimano site but didn't see anything about it.

The new Colorado Cyclist catalog has them. They sell the rings in 54-56 teeth for $89.99.

... more rigid than the standard Dura Ace ring (especially the larger sizes)... and, generally used as a single chainring... specifically for TT's.

I've been running standard Dura Ace 56T on my TT bikes... but my latest ride will get the buzz saw.

Be the bike.
Thanks. Info and questionDuane Gran

Thanks for the info. FYI, now that I knew better what to look for, here is from Colorado Cyclist:

It sounds like you use just a large ring for your TT bike with no front derailure. Is this a common setup? This is interesting, and as I think about it I can see how this would be a good way to go. What kind of rear cassette do you tend to use in this case?
"Double" DutyAkirasho

My TT bikes usually do double duty so I DO have a double up front on three of them... but the latest ride will be sans the front der and ring and used specifically for flatland courses. Locally, most 90 percentiles run without the front der on dedicated bikes.

Indeed, I've never actually used the small ring during a TT on the other bikes (nice for warmups though), but have used it to climb on training rides... I'll probably end up removing the smallie on all but one of the bikes.

In back, I try to stick with a straight block 11/21 on all the bikes... I've only successfully pushed the 56/11 for any significant distance a handful of times (still working on knee rehab) but wouldn't it be sweet if I could spin that sucker at 100 rpm??? (I wanna be like Lance)

Be the bike.

P.S. I was at a LBS this morning when the owner, knowing the illness I suffer from, shamelessly took advantage of me and produced a bare old Cervelo P2 frame... in my size (but with 650C)... I've got a P2K (700C), but wouldn't be nice to have a family???
