MTB rear wheel

08 Aug 2018 18:27

Hi

I've just been gifted what looks/loooked like a pretty nice MTB via a 'Buy Nothing' Facebook group. When I picked it up I could understand why it was free!

There are lots of minor issues that I can solve, but the main one is a pretty badly buckled rear wheel. Initially I thought I might be able to sort it with a bit (a lot) of use of the spoke key, but I'm not sure. If I replace then I need a 26" wheel that takes disc brakes BUT the gears (Shimano) are 7 speed (a surprise).

The problem is that I dont see many wheels for sale that are 7 speed - but do see mention of spacers for 8/9 speed, etc. I'm very out of touch on the tech side - is that something that would work? I'm looking to spend on a budget basis - the idea being that I donate the bike to my son for Uni next year.

Any advice would be much appreciated.

Just adding to this - a lot of the advice I have had is that its not worth trying to stay 7 speed and that I should upgrade to 8/9 speed. Thats nuts to me - that would be new shifters, etc.

If the rear spacing is 135mm, get a 8/9s rear wheel and use a spacer onto the freehub body first, then your 7s cogset. If you cogset wears out, get an all loose cogs 8 or 9s cogset, remove a(or 2) cog, use the spacers in the present 7s cogset..adjust rear der..go ride.
