When changing gears I was pushing too hard, which made the chain derail. Then i cranked again before noticing, and it bunched up, and bent the middle sprocket pretty badly.
Is this an easy part to replace for a biking newbie with decent mechanical skills? It is the middle sprocket on the front (pedal) crank.
Or should I just let my lbs fix it?
(I hope my chain didn't get bent - it seems to work fine when not on the bent sprocket, so...hopefully it didn't!)
Are you able to replace individual rings? Or is the whole thing an assembly?
