Fox 34 Rythym rotor upgrade
Hi, I'm want to upgrade from 180 rotor to 203 rotor on my fox 34 rhythm fork, with magura mt5 breaks. Please can someone confirm which adapter is required. Many thanks.

This is probably what you want:
QM 44 ADAPTER for PM7" PM 180 to 203 mm rotor. That is what I am using on my similar Fox fork with same brake:

Hi, thank you for your response. I fitted the the Qm44 yesterday but it was too small. I have since found out the the fox 34 rytham standard size fitting is for 160 rotor, so I'm going from 160 to 203 and I believe the adapter I need is Qm42 PM6. I will try this adapter when it arrives in the post later today and update this thread. Hopefully it will fit.

Hi, the QM42 does fit, but its strange fitting as you don't screw through the caliper then through the Qm42 and onto the fork. The QM2 screws onto the fork with supplied bolts then you need to screw the caliper but no suppled bolts. I used the old bolts but had to cut them down as they are too long. All up and running now.
