Um I dont think so. Not in winter, but im not 100% sure. The teeth are really, really worn... so the chain catches and on every revolution the chain 'balances' on top of the teeth, before dropping back into place.. My old chainring is 4 bolt so cant use that. Yeah sorry didnt come out, I got up at 2 and spent most of the day fixing my bike, and its still broke Wasnt feeling too good either after last night so dont think i'll be drinking much tomorrow.. Apart from loose cranks and a fudged chain ring, im all set
