    Hope brakes and 180mm rotor

    I bought two sets of hope brakes.

    1st bike set: M4 Front X2 rear

    2nd bike set: X2 front X2 rear

    On both bikes I would like to run 180mm rotors for the front.
    The adapters I have are the Hope 183mm adapters.

    Is there a way to run 180mm rotor front on both bikes? What kind of adapter would I need since the Hope one is for a 183mm rotor?

    Hope brakes and 180mm rotor

    Would 1.5mm really make a difference? Maybe remove some material from the adapter?

    I've read yes 1.5mm makes a difference when the pads start wearing down.

    You will likely end up with a ridge on the top of both pads that will eventually touch and not let the pads close completely on the rotor. If it were me I would get the Hope rotors, mine have been fantastic as have the brakes, I have two bikes one set m4/x2 the other x2/x2 with the same rotors. Or you could get the correct 180mm adapter from another manufacturer, that would be the cheaper route.

    Happy trails...

    Yeah I just used hope rotors with mine and I think they are 185 not 183 but I could be wrong, been a few months since I did the rebuild.

    Hope does use the 183mm rotor, Avid used to use a 185mm but has since switched to a180mm. Not completely sure why Hope uses the odd ball rotor size.

    A divided industry that can't agree on a 5mm difference.

    Hope step-up mount 'F' (for a 160mm rear rotor) will enable you to run a front 180.

    It's all about proprietary parts.

    OP, get the right adapter or right rotor size. Contrary to what women tell you . . . size does matter.
    Alcohol may lead nowhere, but it sure is the scenic route!

    Valid point, every ones has to sell more parts. i do like the floating rotors very much though. nCan certainly tell a difference on a longer ride with lots of braking, I find the rotors pinging as they cool down rather fun and fade isn't much of an issue even for a big guy like me.

    mount F is for IS mount... i assume the fork is quite recent and required POST mount adapter for the front.

    I've got a barely used set of 160mm Black Floating rotors if you are interested.

    I would mount your 180 on your wheel first and check the pad vs rotor alignment. There are small variances in fork post/tabs. I run two wheel sets with 180 and a third wheel with 183. One fork I have a Hope F post mount adaptor and the other fork I bought a Formula IS 180 adaptor. All fit like a glove. The 183 is run on the bike with the hope adpt and I don't have to adjust anything between switching wheels.

    I found my Shimano 180mm rotor adapter works well with the hope brakes. Thanks for the suggestions.
