• Total disc neophyte here, pardon my noobness and possibly my inability to utfs. I was planning on running a 180mm front 160mm rear combo on some Shimano Rx010 centre lock wheels. Having just looked at the Rx010 spec sheet though, Shimano describes them as 140mm rotor compatible. Can I put a 160 or 180 rotor on there or will I need a new set of wheels?

  • Shimano describes them as 140mm rotor compatible

    Wheel compatability is minimum rotor size, the spokes will clear the specified calipers with a rotor that size. Bigger rotors will only open up that clearance.

  • Brilliant, thanks. That makes sense. I'm not ashamed to admit I was struggling with Shimano's definition of "compatible" here.
