The definitive OTP ( Off-The-Peg ) List (<£500 and <£1,000 sections)

...Am I likely to be able to replace the rims/wheels on the 2010 model for something of similar standard for around £50?
cheers

No.

Probably looking at £100 even if you build yourself. Or you could remove the rims and lace up some new ones on the existing hubs which would get you closer to £50 using an Open Sport or similar and lacing up yourself.

^ this. Except get these rims instead of the open sports get the DT Swiss on sale from planet x - for £70 + £20 for spokes. You'll end up with a really nice set of wheels, and I'm sure you'd be able to sell the rims for at least £2-30.

Or just rattlecan the rims.

And the Ridgeback is pretty good. Its basically the old genisis flyer with a bit more room.
