TheDoctor said:Simple answer is 'It depends'. If it's a steel frame this should be fine (in fact, some frames are 133mm so you can use either). Carbon or alloy you're risking cracking the frame. Don't know about Ti.
I'd just add another locknut on either side of the axle to take it to more like 135mm.

Not saying i'm right, but surely theres going to be an issue there.
