Check your U-factor (crank width at the axle) before dropping cash on the Rotors. They are not the best in that department, I had to switch to 0 float cleats on them.

It's less than a mm either side diff compared to a Shimano crankset. I'd be wider if I kept that and switched to SPD-SL pedals than switching to a Rotor crank and keeping my Keo Blades. And there's even a version of SPD-SL that's 4mm wider per side than that!

How does switching pedals affect U-factor, unless you're talking only about the difference between Q and U?

Ah ok, tbh I thought it was a typo :P

I guess I've never even thought about U factor because I pedal straight anyway.
