<I don't have much else to add, one question: did you buy the bike new or used? If used, there might be enough wear to scrap a BB, but still sketchy. If you bought it new, then this is a repair and part the shop should cover - period. I can't think of any reason a hub should fail that quickly w/o other signs of unusually hard use. As for the chain, there are a few people who feel that 1/8 chain is more robust, but I think the vast majority of people i know don't think there is any significant difference going to the larger size. >
Yeah I bought the bike new. Rode it SS for a couple of weeks, then switched over to fixed. I guess I've done close to 500km on it, so it did surprise me that the components would wear out so quickly.
