Hi,

Hope someone can help. I was in the process of switching my brakes to a set of Hopes and have noticed that my floating rotor is rubbing quite significantly against the lower part of my forks post mount.

The forks are BOS Deville's, and the wheels are Mavic Crossmax Enduro's. Without the bolt through tightened there's no rubbing (it's very close, but not touching) but once done up the fork leg pulls inwards and touches the spider part of the rotor.

I have noticed that when you put the end cap on the hub and drop the wheel in the forks there seems to be a bit of a gap, almost like the end cap could do with being a bit bigger?

Any suggestions? I could of course drop the floating rotor idea...but I do love them so! :-)

Any help would be much appreciated

Cheers guys


Jamie

    Typical problem created by wholly unnecessary floating discs I'm afraid, they achieve nothing and come with a lot of downsides (and are pretty rubbish with Shimano brakes).
    Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.

    Well i love them and work well with all brakes, shimano, avid but no with formula r1 callipers due to rubbing. Not heard of them rubbing on forks, not heard of your brand of fork.

    You may one or two options, file down the post mount on thr fork but make sure therr is pkenty of meyal left, simpker is to try different floating rotors, e.g. formula, theh are not as light but habr flat holloe bolt, possibly avid.

    A good but cheap brand of floating disc is Deckas, about "£7 on ebay, as light as hope.

    You love them?

    You need a woman. Or man, whichever way you swing.

    As Rookie said, pointless on a bicycle. Create issues sometimes, no lighter, why bother.

    Motorcycles are different.
