I’ve just installed a son dynamo disc hub and unfortunately the spokes slightly foul the caliper. Only just, the wheel rotates but there is a ticking noise and it’s the odd spoke slightly clacking on the back of the caliper body.
Does anyone know what is a fairly narrow caliper, or can be arsed to measure the centre-of-disc to the end of the body distance on theirs and let me know if it’s less than the 18mm/19mm of mine?
It is a hope x2 race about a couple or three years old and the disc is a shimano centre lock one.

Could you not put on a +20mm adaptor and use a bigger rotor? Solved the same issue I had on the back of a bike a while back (went from 160 to 180)

Can you use shims to space out the rotor from the hub a fraction and then the calliper as well?

Yup, Hope spacer should do it.

Hope/rotor spacer won’t work with a centrelock rotor.

Hmm, 180mm rotor idea might work. Didn’t think of that.

anybody know what adapter I would need to convert it to a 180mm rotor?
this one http://www.chainreactioncycles.com/hope-post-mount-to-is-disc-brake-adaptor/rp-prod13737 possibly, but 183mm or 180mm??
