I have to admit that after riding an old steel frame for so long i was a bit dubious but a couple of 40MPH+ runs down some of my local hills has given me faith. I can honestly say that it felt alot faster and seems to accelerate very quickly, I can achieve 30MPH on the flats now where on my steel frame more 25MPH according to Strava. The carbon tubes are screwed as well as bonded and I suspect the carbon thickness is quite high compared to a modern frames.
