So last week at gore I was screwing around and my lowest gear spun loose. Took it apart and the hub snapped at the end where the cassette threads in. I can still ride it I'm just missing a gear . What hub should I get ? It's a budget bike and I'm a beginer so it doesn't need to be the best. Just decent. The derailer and cassette are shimano deore if that matters the rim is 24" and brakes are 9"Hayes I beleive.
