I just got into road biking two years ago and racing last year. That's kinda the point I was trying to make though. There's a great distance between where I'm at now and where the difference between a more aero rim is what will win/lose me a race.

On the flip side, I rode an extremely competitive race last year - average speed 41kph for 2 hours. I placed 11th (for tactical failure) out of a field of 92. There were a lot of zipp wheels behind me.
