  • 7 speed cassette on a 9 speed ?

    Want to put a 7 speed cassette on a 9 speed wheel. Was planning on buying a single speed conversion kit, one with lots of spacers and using these. Would this be a good way to go?

    Hope do a spacer for £3 odd IIRC.

    Single spacer would be a cheaper idea. Wheels Manufacturing do one for £2.49

    Thank you, shall check the single spacers out. As for why I think that would be obvious?

    yup, you just need a spacer.

    7 speed for the win!

    A half retro bike?
    You want to keep your 7 speed shifters but don't want to take advantage of a stronger 7 speed wheel?

    7 speed wheels are barely any stronger.

    upgrading a 7s transmission to 9s costs £££, as do replacement transmissions.

    DUH.

    Half retro? I am simply building up a singular peregrine frame. Money is tight so looking at buying a pair of on-one 29er wheels which I see as a chaper option than a 7 speed disc compatible 29er wheel. Will be using my 7 speed deore thumbies and 7 speed xt mech. I may or may not upgrade to 9 speed kit in the future but for what I want the old 7 speed kit will do nicely. It has worked with out any problems for the last 10+ years and I believe there is plenty of life left in them. There will be nothing Bling about this bike.

    I had the same dilemma, sawed through the pins holding the old cassette together and used one of the plastic spacers from between the cogs behind the new cassette. Works a treat.

    I am simply building up a singular peregrine frame. Money is tight

    these two statements do not match up

    There will be nothing Bling about this bike.

    except a frame that costs more than most bikes

    ballsofcottonwool, tell me how much a singular peregrine fame costs please as it looks like I have been looking at the wrong price. As far as I can tell they retail for £540 which is why money is tight for the build kit. I expect that this is not more than most bikes, in fact it is less than most suspension forks. Right then, a road frame that will take 2 inch tyres, has braze ons for panniers, full mudguards and three bottle cages. Drop bars and kitted out with the chain set of an very old marin pine mountain. Not really bling, is it.

    Double checked the price. £540, about a grand less than a Turner 5 spot frame.

    By "Deore Thumbies" are you talking about the xt or DX thumbshifters? If so then are you aware that they have an extra click? You can run them 8 speed fine.

    Just deore. they look just like the xt ones but have silver tops instead of gold and just say shimano deore light action sis 7 s on them. If there is an extra click in them I can't find it. Could turn the index off which may work on 8 but not really bothered about the 3 extra gears.

    I've heard this said but never seen it work well.

    Odd. I always thought that those two were actually mechanically the same, but the XT just had different labels and an ally clamp rather than a steel one.
    Anyway.. If they shift past 7 then they will work. The extra gear doesn't have as distinct a click as the others, but friction holds it fine. The mech will work fine too.
