I love the ride of the QB, but I like gears and never wanted to get off the bike to shift. So I bought my QB with schemes of somehow making it a shifter. Right now, it's a 3 speed shifted at the crank (24-36-46) with a front derailleur and only one cog in the back. (I use a friction bar-end shifter on the handlebar to operate the front derailleur.) A derailleur in the rear is used solely for the purpose of maintaining chain tension when the front radically shifts.
However, I still want a lower gear. Since this frame seems to have survived a car accident, I'm moving forward with plans to install Alfine 11 into it and using a single 36T chainring up front and removing all derailleurs. The effective gear ratios appear excellent on paper: 0.825 as the lowest and 3.36 as the highest. I have to spread the rear from 120 mm to 135 mm, but I'm going for it. Waiting for parts to arrive. -Jim W. On Jul 7, 2011, at 10:41 AM, Larry Powers wrote: > How often do you shift your QB?
