I might be able to go in on the front, i've been after a campy deep-section hipster wheel for a while now...
How much would you split them for? £120/£80?
I might just be dreaming but I'll have to check my bank balance.
Also, I'm not in London.
Rear wheel's aren't worth £40 more than fronts in my opinion. I'd think that £95/£105 would be more appropriate as you can get new 8 speed cassettes for around £12.
