First commute today on the CX. Only done 24 miles but so far no problems, apart from minor tweaks to seat and bar positions required. Front mech is very smooth, rear is stiffer than my SRAM Rival. Brakes were fine, no drag or noise apart from when I braked when they were wet, but they work fine. Didn't notice any difference in rolling resistance from the larger tyres but it did seem more comfortable.
Still waiting for my mudguards.

and I have been trying to work out what mudguards to go for. Are they 35 or 45? I am fitting 28 tyres, I did not know you could go down to 25. I have gone for a Topeak rack as I already have a beam rack and bag which I want to carry on using.
