A special thread for all the weight weenies out there
A fast bike on flat roads is about rigidity and aerodynamics, not weight.
All the "bollockle" talk about rotational weight, and accelerating a certain mass from x speed to y speed requires 'this' much energy, etc, etc...blah, blah.....check out the heavy weights of some the track bikes at the recent World Championships. And being track bikes, they obviously don't have cassettes, brakes, etc.
Plenty of people on this forum wouldn't go
near a road bike unless it was under 17.5lbs (8kg)! Theo Bos got his 17.5lb 'clyde' up to 44.3mph without a tailwind!
Damian Zielinski's Isaac.............16.3 lbs
Clara Sanchez' Look...................17 lb
Roberto Chiappa's Pinarello.......17.3 lb
Maximilian Levy's FES.................17.4 lb
Theo Bos' Koga/BT.....................17.5 lb
Dutch team pursuit Koga/BT.......17.8 lb
Stefan Nimke's FES.....................17.9 lb
Tuen Mulder's Koga/BT...............18.5 lb
Dutch team pursuit Koga/BT.......19.2 lb
Dutch team pursuit Koga/BT.......19.4 lb
Dutch team pursuit Koga/BT.......20.7 lb

Accelerating a mass from 0kmh to 60kmh+ is more important in track events than anywhere else, but some of these bikes are close to, and over, 18lbs!!!

And if anyone says that the big guys need big bikes, the pursuit guys aren't big, and look at the weight of the Dutch-owned BTs
