Well it looks like its about time for a new rear 9 speed diskette and a chain. What do you guys recommend for me?
If you are a shimano person go with an Ultegra cassette. Cheaper than Dura Ace, more durable too yet very quick shifting.
I think you mean Cassette not diskette.... that said ... for road Shimano 105 or Ultegra for mountain bike Shimano XT
