Help. How can I shorten my Q-Factor

[satanas]

^ I think what Q factor might suit varies with individual biomechanics, so it's hard to generalise and predict what might work for someone else. In my case lower Q makes my knees happier and increases my ability to spin, plus I spend more time on other bikes with 140-150mm Q, so keeping things similar eases adjustment - as does keeping crank length the same IME. FWIW, one bike has those 174mm Q XT cranks in 175mm, and I'm intending to swap them for 163mm Q M985 XTR cranks in 172.5mm. Past experience suggests this will make a significant difference *for me*, but everyone is different.
