My mate has an old Cannondale F4 circa 2000 and its got milk bottle tops for discs and cable brakes.
(not to mention a headshock that is shocking – but he hasn’t ridden anything with proper suspension so doesn’t realise that yet)
You cant lock the front or back wheel at all, not even in the carpark stood next to it. He has asked me to help him spec some better brakes and I wondered if a set of basic Shimano hydraulic brakes would fit. But they all seem to be post mount.
Can you just buy an adaptor ? Or does someone sell brakes that would fit ?
Oh and he came out on the weekend without a middle ring (he’d worn it out so removed it) so the poor chap spent the whole ride in big or granny and a gap that caused his chain to fall off in between. Anyone any idea of what replacement ring I need. I cant recall what cranks he has, but its standard, he’s not replaced anything since buying it new.
