The "float" is the expansion of the steel disc due to heat, the alloy centre "guides" the disc, it is not a side-to-side float.

ransos has a good reason to "need" them :wink:

It does not have any side to side or self centring movement so no difference to alignment - there is no alignment issue on motorcycles anyway.

It does two things - allows the use of an alloy centre so saves a bit of weight and reduces warping as if the outer gets hot enough to expand it can expand a tiny bit on the buttons so does not warp by being firmly attached to a cooler centre

As on motor cycles.

I thought that venting helped dissipate heat. and cross drilling combat glazing.

Solo.

They are better for heat dissipation.

You need wide bars as the brake lever needs to be about 2 inches inwards of the grip for proper 1 finger braking. The old lever is much better for xc.

I love hope brakes, but my 2 week old M4 blew a piston seal today ... grrrrrr!
