  1. Got on the bike this morning to come to work, first time in a while. A wee while ago I was muttering
    about gear ratios as I wanted to make my bike easier to ride -
    makeashorterlink.commakeashorterlink.com

    Anyway, to cut a long story short it's taken me over a month to fix the chain so that it runs
    smoothly. I ended up doing it this morning and nearly slicing to top of my middle finger off when it
    got caught in amongst the still rotating spokes.

    So everything looked hunky dory, except the rear deraileur (sp?) travel, but I figured that since I
    could still engage every gear except for first and last on the rear mech I would still be able to
    get to work and back.

    However, on the small ring at the front and on the third sprocket from largest, I can't peddle with
    any force as the chain is either slipping or jumping. I think it's slipping as it's not making the
    same sort of noise it makes when it really want to be in another gear.

    I'm pretty sure that I got the length of the chain right, so I'm wondering what the problem is.
    Could it be that my rear sprockets are worn and thus not gripping the chain, or something else...?

    Cheers,

    P.S. I'm now off to Sheldon Brown's website to figure out how to get back top and bottom gears.

    Most likely. New chains don't get on with old cogs, generally.

    I am now resolved, having been though this a couple of times, that chain/cog problems = new chain,
    new cassette , no fiddling about. Life is too much fun to waste on such things.

    Yesterday I bought a new Shimano HG 12-21 rear cassette, don't know when I'll get a chance to fit it
    over the weekend thought. Hope this fixes the problem...
