    New question here. Shimano Ultegra 6500 9-Speed Cassette

    Will this cassette work with my setup, LX shifters and XT rear derailleur and 9 speed chain.

    Also what do all these numbers mean exactly:

    11-2-3-4-5-6-7-19-21

    14-5-6-7-8-9-21-3-5

    Yes it will work fine. Those are the sizes of each individual cog. You might want to go ahead and replace your chain at the same time.

    Like Blonde said... I would replace the chain as well. The chain and cassette wear together nd you should replace them together.

    As for the cog size I'm pretty sure the 14-25 is for junior road race gearing so kids don't blow up thier legs. With that being said I wouldn't run a 14 as your largest cog on a DH bike. I would get something that is an 11 tooth or atleast get a 12 tooth as the smallest. 11-23 or 11-26 is the way to go in my opinion.

    thanks for the info

    what i had planned to do was have an all mountain wheelset and then a DH wheelset, so each wheelset would have a different cassette

    so i guess the smart thing to do would be to swap the chain everytime i swap the wheels...

    Agreed.

    My newer 7Point has become a bit of a mini DH bike lately. I'm running a custom 6sp cassette (with 9sp spacing) with an 11-12-14-16-18-21 tooth combo and a 34t ring and I'm LOVING that setup it shifts super quick and crisp and with my XTR shifter I can get through all but one cog in a single throw.

    DEFINITELY. It won't shift right if you don't.

    You can still get 12-27 ultegra cassettes, I just picked one up a few days ago.

    As all the roadies move to 10 speed these will start to be discontinued.
    It's started to get a little more difficult to get the 9 speed now.
    Stay off the brakes

    7sp cassettes are readily availible from most suppliers. 9sp cassettes aren't going anywhere.
