    Hi Guys,

    missus bike, as we have established before, is on Grip Shift (urgh)… I want to convert it to rapid fire…

    Can anybody recommend anything for an 18 speed?

    Will be diffo, as IIRC, R/F are for 7 or more gears. Might have better luck with 6-speed thumbies. 🙁

    yeh if the hub allows change the sprocket, and if they wont fit then you’ll have to do something with the spacer, steve kish was telling me about it i think

    Yup, if you can break down the 6-speed cassette, you should be able to re-build it with 7-speed spacers, thus allowing the R/F shifters to work.

    7-speed have 5.0mm spacers between them and 6-speed have either 5.5mm (Accushift) or 5.3mm (standard).

    Alternatively, I have a few used but not worn 7-speed cassettes here (13-21, 13-28 or 12-28) if you wanted to try one out.

    who needs gears anyways… my road bikes down to six speed 😛

    Yeah, OK. Tell you what I’ll do.

    Choose the one you want and I’ll post it – if you like it, send me £5 plus the cost of my stamp. If you don’t, send it back with just the cost of my stamp.

    Just so that we’re in the same aisle of the supermarket, these measure just over 34mm from the back of the cassette to the very top of the locking ring. They are Shimano Hyperglide with the wide spline. If unsure, read about it here; Sheldon Brown’s pages are ‘The Bible’ with me, God rest his soul:-

    PM me your address, if it looks like a goer. 🙄

    May not have a Hyperglide freehub, in which case, my 7-speed cassette won’t fit it. 🙁

    Take the back wheel out and see if it has anything written on the locking ring. Should say summat like ‘Shimano HG’ or ‘Hyperglide’ and the words ‘Lock>40Nm’, or similar.

    Looking at that spec I reckon it probably has a screw on cassette cluster

  • Steve Kish

    May well have, as 6-speed cassettes are pretty rare. 😥
