Just to add a bit more about the bike and set-up...
I recently bought my Cyclosportif frame off ebay and built it up with new Campag Centaur kit but used a pair of 36-spoke Veloce/MA3 wheels which turned out to be overkill. I use ITM bars and stems and tried out their new(ish) Forged Lite seatpin with my B17. I built my bike up quite easily and had a short spin on it a few days before setting off and thought that I was all set but I hadn't quite realised that my new Carradice Super C saddlebag would sit on the rear wheel (this seems so obvious now but I've never used one before). Luckily, I had an alloy rear rack to the spares box and made use of the Cyclosportif's rear eyelets to keep the bag off the wheel! Unfortunately, this particular Cyclosportif had no pump peg so I bolted a Specialized mini-pump onto the side of a bottle cage which looked a bit untidy but thankfully wasn't needed.
The top tube is just 5mm shorter than my Bob Jackson custom-built frame so I felt quite at home on it and found the frame to be stiff and efficient. With a steel fork, heavy wheels, big saddlebag and rack then the weight seemed really heavy when I picked the bike up but on the road it was hardly noticeable and the handling was superb. In particular, this bike was the best 'descender' I've ever had and I feel that it's to do with the steel fork and oversized steerer - it just feels rock solid. There was a lot of up and down on Day 3 and the confidence I gained in this bike on the long, fast descents was amazing.
The groupset performed faultlessly at first but a bit of cable stretch must have crept in which affected just one gear (gear 4 - the 16t) but I lived with it. The wheels were a bit heavy though and I've now picked up some new 32-hole Centaur hubbed wheels although I'll still stick with 25c Conti tyres until it's mudguard time and might need to go down to 23c's.
I haven't done a lot of cycling really so three consecutive 'century' rides were a bit of a stretch for me but the bike was fine and I might just have become a convert to Brooks saddles. After five rest days (well I was on a family holiday!) I sat on my B17 and it just felt fantastic - so either it (or my ar5e) have been broken in!
