I’ve just transfered most of the kit from my Pitch (frame for sale BTW) to a Nicolai Helius CC, the mahoosive Hayes Stroker Ryde brakes 203mm front/180mm rear are proper overkill.

I want to put the 180mm rotor on the front so I can just use the rear mount on the front, same fitting so shouldn’t be a problem?

I tried a Shimano 160mm caliper mount on the rear but the caliper fouled the 160mm disc by quite some amount, I thought this would be fine?

Any ideas where I can get a Hayes 160mm rear mount from?

BTW both fork & rear are IS mount and so are all the caliper bracket things
