Sherlylock came round last night, with the vital chain whip, and with his help I managed to shift the cassette. Many thanks Mart, I really appreciate your generosity. So now I have this:
I have simpley screwed the smallest cog back on, will this work? the bike will be mostly used on road, and the front ring will be 32t.
another problem that I had was a stuck bolt in the crank, I bought a set of screw extractors from my local cheap shop (they cost £1!), screwed the extractor in and the bolt came straight out.
So the Muirwoods is moving forward again, got a Dirt research polished stem delivered yesterday, which should be perfect, and am hoping for brakes and bars today....
Mart had a look at the headset, and thought that I need a washer between the two top nuts, so will be sticking a wanted ad up for two 1 1/8inch threaded headset washers, I need two as Mart needs one as well!
