Most amateurs have signifcantly more time they can cut by training better and harder than spending thousands or tens of thousands on better components.
Its a very small list of amateurs who train to the same level as a pro who has a good chance of winning any of the big competitions.
Stick that under 30s pro on a cheap bike geared the same as a midlife crisis amater 45 year old gear head on an ultra expensive bike and guess who wins?
If you want to buy wins enter an amateur car racing event, those are mostly reflective of money spent given a base level of talent and training (which costs far more money per hour than training for cycling).
