    Chain comes off cassette

    I had my LBS perform a full tune up before my first ride on my new evo about 2 weeks ago. On my last two rides my chain has come off the cassette, falling in between the cassette and the chainstay when I'm rapidly shifting thru gears. Any idea why this happens? Should this be fixed by the LBS that did the tube up?

    Did they just do the tune up? If so I would just bring it back to them and tell them what is happening. They should resolve it for free.

    Sounds like just an derailleur adjustment issue. The high limit screw probably justs needs to be adjusted to move the derailleur in a little to keep the chain on the cog.

    Sounds like a limit screw adjustment like mentioned above. The shop should do it in about a minute.

    Or look up a video on adjusting an RD and do it yourself so you're familiar with how it's done. It's not difficult.

    Very true learning to do this level of maintenance yourself provides you with some good knowledge that can save time and a trip to the shop. A little clockwise turn of the H limit screw on the derailleur should solve your issue. Much easier if you have a workstand so you can spin the crank and shift to test without having to ride it. Very easy should take less than a minute to do.

    This sounds like an easy fix. I'll give it a try.
