I am doing a rear wheel swap and I have the sprocket tool with the chain, what else do I need? Is it just a socket? Please excuse my lack if knowledge on this but I am trying.

If its a shimano/sram cassette there is a serrated tool that removes the lockring on the smallest cog end of the axle. One of these:



The chain whip is to stop the cogs moving when you undo the lockring.

The only other thing you need is a cassette removal tool, which simply slots into the locking nut on the outside of the cassette and then unscrews it like a spanner (whilst you're holding the cassette in place with the chainwhip).

Did it for the first time at the weekend and it took 5 secs to do (once I'd figured out that a chainwhip was also required). There's a load of videos on YouTube that show you how.

cheers Chris, it's a Mavic CXP22 that I am removing and putting on a Mavic Open pro.

This is the Cassette side of the new wheel

Hopefully this helps. To me it looks like I need and Allan key bit.

If you have the bits, it's really easy.

I'm a bit of a mechanical retard and I can do it, so I reckon anyone else can.

All my bits for it came with a £30 'bike mechanic' set.

I'd feel confident doing it, it's just the tools needed that I need.

Curtis,

Can't see the photo. Can you upload or send link again?

Cxp22 and open pro are the rims I think. What hubs are they?

The picture shows the new wheel and that is on a shimano 105 hub, the hub that it is replacing, i have no idea.

A good tip is to use the skewer to hold the splined removal tool in place. Once it's done a quarter turn (or less sometimes) it can be unscrewed by hand.

I got one of those from Tredz or Chain Reaction a couple of weeks ago. Extremely useful.
