They are racing against a time. You are spending money. I know what you are saying. I've seen cyclist spend 200 bucks for a new saddle they did'nt need because it was 10g lighter. They did'nt race but got it anyhow and to be that is dumb. For me it would be dumb to spend 100 bucks for a single 3ft cable. I'd rather just get better equipment for more of a benifit then a $$ cable,but thats me. Now if i had high end stuff,then maybe. I kinda lean more on the hype then substance.
