Does anybody happen to know the Q factor for a Chorus Compact UT 10 speed crankset? I'm trying to do a comparison between it and a Shimano FC700 Compact crank (which, it seems, has a 147mm Q factor). Anywhere I should look for the info?

its actually written on the arms themselves, right by the pedal hole, looks like 143.5?

try and find a high res picture and check it out, i think all the UT cranksets are the same

has to do with "spread out" from bottom bracket.(ie distance from one pedal to another- so leg spread)

I have never had a problem with using any of the major ones. (CAMPY, SHMANO, SRAM, FSA,) pete
