in fact thinking about it - rather than invest £250/£300 on a new frame and wheels I would probably be better buying a new bike??
I could probably get £100/£150 for bits and piece on my bike and then spend the £300 or so i was going to spend on wheels/frame towards a new bike. By the time i messed about trying to change everything from my old bike to a new frame no doubt I would end up spending more on various bits and pieces!!
There is some excellent bikes about for around £600 or so at the moment from a quick look round.

with 20% off and another code i found takes this down to £610!
Also the boardman range seem to get an excellent write up as well.
