Last weekend I upgraded the wheels to Fulcrum Raching 7 CX's for £128 (plus £5 P&P). I needed the CX version because the tarmac lanes I cycle to home resembles a dirt track at the best of times with 8 nasty n-style speed bumps (think 1980's sleeping policemen if you were around then). My alternatives are 2 dirt tracks which are both very lengthy. I am loving the new wheels. So much smoother than the stock wheels. Freewheeling is much easier, more often and quieter and did I mention how much smoother the bike is?

Delivery from Germany took 3 days (ordered monday pm, delivered thursday and I have a house most delivery drivers fail to find!)
I changed the tyres almost immediately when I got the T3 in September going over to Schwalbe Durano pluses. If you are not used to the extra weight of this range the may seem slower than lots of other tyres. but I love the grip and the confidence I get from them and given the distances I cover, I prefer not to have too many fairy visits. Only the 1 so far and that would have taken out a car tyre.
PS - did I mention how much smoother the new wheels are?
