Hi, so, i havent had a bike for ery long (havent tode it all that much either) but, i was wondering about lubing the chain. Ive heard of lubing a o ring chain breaks down something put on there when it was made? There was a new chain put on my bike before i got it, so would this be an o ring chain, how could i tell? And, wht kind of chain lube should i use if i need to? Thanks!
