Question about increasing Q-factor(4 posts)

Question about increasing Q-factorD_man

I know most people often think about ways to decrease Q-factor, but due to some problems with illiotibial band syndrome (ITBS) that I have encountered for the first time ever since taking up crossbike riding, I am looking for ways to increase Q-factor a bit. I've experimented with using pedal spacers, but can't get enough extension that way. So I'm thinking of going to MTB cranks, which usually have a higher q-factor (Right now, I'm running Truvativ CX cranks w/ a 113mm bottom bracket). Does anyone know if particular brands of MTB cranks have a relatively high or low Q-factor? I was thinking of going to Raceface turbine cranks, but have no idea how much of an improvement that would be over the Truvativ CX cranks I'm running now.

Also, would my current BB allow me to run a triple MTB crank, or would I need a longer spindle?

The old Syncros Hardcore Tubular Steel Cranks (both road and MTB versions) I'm a larger guy and my body size just works better with a higher q factor. look on ebay and such

Why not just use a BB with a longer spindle? Looking at their web site it appears they have a 118, that would maybe do the trick. I think they have a 128 too if you want it REALLY wide

longer spidle will increase q but sacrifice chainline, shifting etc.... not a great solution.
