    Hi everyone.

    I am returning to mountain biking after a 10 year absence, mainly due to cheap travel to work and fitness.

    I have a Saracen Trekker hard tail which is 17 years old now. It has been upgraded in the past and has 21 speed LX group set. The rear derailleur is siezed and needs replacing, but can’t find a new 7 speed derailleur.

    So my born again biker question is: Can i fit a 8/9 LX rear derailleur with a 7 speed cassette and shifter?

    Cheers

    Shimano Alivio M410 is a 7 or 8 speed rear mech. and should be able to be got for about £15-£20, maybe even cheaper.

    Try ebay, there’ll be loads on there.

    IIRC, all Shimano mechs (apart from the very early 1980 ones) work with 7, 8 or 9-speed cassettes, as the distance of the throw is governed by the spacers in the cassette and the indexing in the levers.

    Excellent! Cheers guys.

    Just won a New 9 speed LX derailleur on ebay for £19. So i hope to fit it soon and get on the trail to work.
