I’m in the process of rebuilding an old kona shred and I was missing the rear brake mount (for Hayes mx2; old skool I know).
I had a mount left over from my trp spyres and thinking the mounts were standard I thought I’d try that but it didn’t fit. (Both are 160mm) anyone got any idea how to find the right mount as just having a front brake isn’t the best even on a hack bike!
Cheers

Post a pic of what is on the frame and on the brake and it will help.
