Dura Ace (double) spindle length for TCR carbon?(5 posts)

Dura Ace (double) spindle length for TCR carbon?StupidLight
Mar 13, 2003 6:43 PM
For those of you TCR owners running Dura-Ace, what length spindle should I run for optimum chainline?
I've been able to find shell size and threading (68 english)info for TCRs in older threads, but this last spec. has eluded me.

The one and only size is 109.5 for doubles.
No aftermarket options? Stock ISIS FSA crankset with Shimano?StupidLight

So is Shimano not licensing their spline pattern to anyone else? I've always found Shimano BBs to be a bit on the heavy side, to be perfectly honest.

I know from my MTB experience that most of the aftermarket BB & crankset companies (Race Face, FSA, etc.) have jumped on the ISIS bandwagon, but since I've still got square-taper cranks on all my bikes I haven't devoted much thought to the subject.

The FSA website indicates that their campy-compatible carbon crankset runs an ISIS BB. Is anyone out there running the ISIS (campy) FSA crank with shimano rings?

Shimano allows othe people to make cranks with their spline, but I have yet to see any other aftermarket bottom brackets. Like I said, the only size is 109.5mm. I would love to see someone make a shorter bottom bracket. I've got a TCR with a lousy chainline. With a 12-23 cassette, I can't even run the 53 X 21 without the chain falling off the 53 onto the 39. I've got a lot of room between the crank arms and the chain stays.

I could be wrong here, but I've not heard that Campy is offering ISIS compatible cranks. To call something "ISIS (Campy)" seems WAY off base. FSA may be saying that their ISIS crankset works in a Campy drive train (as would Shimano cranks) but I don't think you can says that FSA ISIS cranks are Campy compatible relative to the BB. Campy is still square taper BB axles, unless I missed the press release.
