Thanks for all the help, it looks like I’ll be buying 2 wheels, cassette, cassette spacer , chainset and chain.
My only concern is that a) they work with each other, ie line up properly and b) work with the Alivio shifters.
As I rarely change bikes, I’m on my third MTB since 1989, and as the tech changes I stay pretty vague on which bits fits with which, and find the on-line parts retailers descriptions of such bits not as helpful as they could be.
I’ll not upgrade at the moment, tempting though it is, the use of the bike –standby/loan/easily shoulder mountable – doesn’t require anything better, it has after all been working fine for 16 years and the problems now are just wear.
I’ll report back on progress, in the meantime here are some pics of the terrain it’s wanted for and why I need to carry it, ie the bits I’m too weak to ride up and to scared to ride down.http://www.flickr.com/photos/43328418@N ... 253312968/
