    Best rotor size - compromise?

    What's the suggestion for my ibis Mojo SL? I'm 90kg (200lbs) plus gear and even my 183F 160R Hope Mono Mini Pro's are fading on long descents (but fine for XC riding).

    I'm seriously considering a switch to Hope Tech M4's but can't decide on the rotor size. Should I go 203F 183R or will that compromise XC riding (except for weight)?

    Any other suggestions?

    Formula The One's are super powerful and Xc light. Make sure you consult with both you frame and fork manufacturer's as to what size rotor's they can handle. Keep in mind that the Mojo SL is an XC/Trail bike, doing long DH descents is not what it's for.

    I disagree... Mojo's are being used for DH racing. Also, there is a difference between long decents and DH. I'm now riding more in the Alps were we can do up to 20min of descending on long flowing single track or fire roads, which are very different than DH parks.

    Also, I'm not looking for brake recommendations -rather rotor size? Should I go with 200F 183R or 183F&R?

    Do you have fresh new fluid through the entire setup and non beat pads?

    Replacing rotors, just buy a 200, and move the 183 to the back.
