Shit picture I know but this is with a 324mm focus rs disk bolted up to the wheel.
Tried getting a pic but there is about 65mm from the disk face to the back of the spokes.
Im quite confident youd get Alcons and 295mm brakes behind these.
Im sure these are cossie gravel wheels anyway aint they which would of been 300/305mm 4/6 pots??
