I replaced the crank on my Xtracycle, and it turned out to be a disaster. My replacement has a Q-factor of 195 mm. I don't think I'm particularly sensitive to Q-factor, but that's decidedly uncomfortable. I'm not sure what went wrong. Rather than clog up the listserv, I told the full story on my blog: http://carfreefamily.blogspot.com/2011/03/q-factor-misadventure.html
If anyone has the time to read through it, I would appreciate any advice. At least my Rivendell has a TA Zephyr crankset, so I'll never try a similar replacement job.
