Gone from a 10kg Boardman cx to a carbon 8.5 kg with semi aero wheels in the last few days. New bike is much stiffer and feel most of my effort is going straight through to the transmission, rather than being wasted on a flexing frame etc. Anyway, picked up loads of PBs on first two rides, but just wondering about the opinions of others who have upgraded bikes and found significant improvements: how much is due to the bike being lighter, more aero and stiffer or am I just trying harder to justify buying it!?
