I have Formula rx disc brake with 180mm rotors.
Does anyone know if Hope saw 183mm rotors will fit straight on ? or do i need a new mount?
Cheers

Think you will need a 180.

I had problems with hope floaters with my the ones.
The rivets don’t clear the calliper. Sold them and got normal rotors, less bling but haven’t noticed any difference in performance.

If it’s floating rotors you need V2 ones as they have a deeper braking surface than saw ones, if you’re just going 183 from 180 just put a couple of washers between the caliper and the mount, it only needs to move out 1.5mm to fit

Cool. Thanks
