Bike technology has been slowly evolving over the last 20 years, and I'm not sure that better disc brakes or 11 speed freehubs really count as great upgrades. I think that the next revolution will be KERS systems, but it will be a long time before racing organizations accept that sort of thing.

So maybe we could say that the biggest advancement in cycling over the last 20 years is "Solidworks"?
