We can argue the details forever, but the fundamentals are the same.

people go sailing on beach cats every weekend, just as people ski downhill for fun. The difference is in the intention to go to the limit and the suitable equipment to do so.

Don't kid yourself that a set of downhill ski's are the same as you can buy for your weekend fun.

Same goes for the bikes, they are specialised for the level of competition and as such they are suited to Olympic level racing and not so much for a fun joyride.
