I just changed my unbranded crankset, which had a 40t chainring on it (was running 40:15), to a campagnolo record crankset with a 42t chainring (now running 42:15) and now my chain comes off pretty quickly. any ideas why?
i also changed my chain so that i could get the tension right. is chainline the only thing i could have got wrong?
