Earlier Mike asked me (with the help of Ed) to fit a wider-ratio rear cassette to the Yeti because he found getting up big hills last night hard because the gearing on the yeti is meant for sprinting and Mike decided he wanted to go home on it.

First we started by whipping the old chain and cassette off and replacing them with a slightly longer chain and a wide-ranging cassette.

It needed a new chain because if we were to run the same length then in the highest gear you would snap the deralier. Then we had to line it up properly using the limit adjuster screws: L (lower) and H (higher) screws with the smallest and largest cogs so that the chain would not fall off into the spokes or in between the lowest cog and the rear drop out.

We then used the cable tension to align the rest of the gears.

If your gears are shifting up well but not shifting down well then your gear cable is knackered.
