I bought a second hand MTB mid year. Broke a rear spoke about a month later (maybe 100 miles on it by then). LBS mechanic fixed the chain routing for me while he did the wheel. No idea how long the original owner had been riding it like that.
OP I am disappointed, I clicked thinking this was going to be a new bike thread.
