What is the "value" they are talkin about. I can understand when 50-kilo Eddy Merckx wants 9 kilo bike, so he can win some other skinny dude with shitty 10 kilo bike. But in which way the 120-kilo american fatty in spandex feels better after these "upgrades"? Only upgrade I truly appreciate in last 70 years was when Shimano moved the bloody bearings to the right side of sprockets. No more bent back axle. Nothing else comes to mind. Correction: Maybe when Nokia made first studded tyre in 1966 was even bigger "upgrade". But this depends where you live.
