The reason mtb Q factor is wider is for the triple crank. They also try to keep the Q factor on mtb as narrow as possible. If they could make mtb Q factor more narrow, they would.
If you want to equal the Q factor, get a wider bottom bracket. Pulling your feet out to exaggerate a knee problem isn't going to help you, but go ahead and try it if you want. It won't damage your components.
No, No, No...
Grasshopper should Think Before Speaking.
I have arthritic ankles. One foot is about 10deg out, the other maybe 15deg. When you ride clipless, the distance between the ball of your feet is fixed. Either I twist my knees to force my feet to be closer to being parallel or my heels are almost into the spokes. F+++ Q-factor. It is meaningless for me. The choices are:
- Hurt my knees
- Catch my heels in the spokes
- Ride with flat pedals
- Quit cycling
- Buy KneeSavers extenders or pedal extenders from High Sierra
I have experience with both KneeSavers and the product from High Sierra Cycling. They are essentially the same thing: a chunk of stainless round stock with a male pedal thread on one end, a female on the other and 2 wrench flats.
There is another thread on this issue, to which I also contributed:
