Hub, Derailleur or chain?
Hi. Maybe someone can help. I have campag shamal ultra wheels and Ultegra (pretty old) rear derailleur. I took my bike for a service recently and the mechanic said all was good - all he did was put new cabling and cable housing on and he said he tightened up my rear wheel (I think) because there was some play in it. Anyway, ever since very occasionally when I put the power on after not pedalling (eg when exiting a corner) the wheel doesn’t engage as quickly as normal - like something isn’t catching. I’m thinking maybe the hub needs servicing or something, but maybe it’s something more simple. It only seems to happen under strain so I can’t recreate it with the bike in a stand - I’m pretty sure it’s not the chain slipping.. Any ideas??! Cheers!
