    Cassettes Warning technical content

    Anyone used an Ultegra cassette for MTB duties ?
    I cant see why you cant and there is one that has the ratios I want.

    What about the materials - will it last in the conditions?

    9 or 10 speed Kev?

    Materials are the same, but is road spacing identical to mtb spacing? If you have a road and mtb cassette to hand measure the overall width I guess.

    I have to admit that riding an 11-34 cassette after getting used to the 11-28 is very odd, I keep thinking I've done a double shift as the ratios seem so far apart

    Thinking more about the individual sprocket spacing vs indexing, I'm not sure the throw is the same for road and mtb*

    If the overall width is the same then happy days

    *Knowing me I'm over-thinking it/being a pessimist

    Well you see MTB rear mechs in use on road bikes, flat bared road bikes with MTB shifters and road mechs.
    I may just have to conform to the Shimano offerings and go for a 11-32 on the back, even though I'm use to 11-28

    All 10-sprocket Shimano cassetes have the same spacing. It'll work.

    If we try really hard, we might not offend him and we'll get double figures for users.

    He is talking 10 speed as there isn't an 11-28 in 9 speed Ultegra.

    10 speed Ultegra and Dura Ace cassettes are actually 1mm narrower overall than 10 speed MTB and 10 speed Tiagra cassettes. But in the real world it doesn't matter and will work fine.

    The question is do you really want those ratios? Personally I found a narrower cassette a real PITA on the MTB, tried a 12-27 for a while, but much preferred a double (and now a single ring) with a wider cassette.

    I've used various 9spd 11-28 (SLX?) and 12-27 (Tiagra?) on the MTB before but that was when I was mostly commuting to work with the occasional MTB ride afterwards.

    What are you up to then Dalesy?

    Nick - What ratio front and rear are you using? And are you using it for what I know to be your local rides?

    Thinking of changing the ASR-5 to 2 x 10 or 1 x 10 but as the ASR is my go to "everything" bike I'm be wondering whether 1 x 10 has enough to allow the country's variety of trail centres and Peaks/Surrey to explored - or would it be a limiting factor?

    I use a 36 ring (with 11-36 block) for absolutely everything, local or otherwise! Really like it, wouldn't go back in a hurry. Only a couple of things have been a bit unpleasant (Mayhem in the mud and Margam), not had a walk, just dug a little deeper than I'd have liked!

    just ideas I'm playing with, got a frame with new F/Mech and thinking triple and looking for a 10 speed rear set up initially with 12-28.
    Currently run an 11-28 9 speed on HT and the XC full susser.
    Mind having struggled with a hill on wednesday I may be looking for a 20-40 cassette ;-)
