We're very happy with the Bontrager Race Lites that came on our second hand Trek. They look cool, and we've have had no maintenance or failure issues with them.
I can't really say for sure that the wheels or the bike make us go any faster because they're, lighter, stronger, or more expensive. I do know that we have increased our efforts as a team since we've upgraded our equipment. I think that's a factor in how lots of other riders perceive benefits, tangible and not, from their purchases. We've made an investment in this better bike or component, we need to ride harder, further and faster to make the investment worthwhile, like self fulfilling prophecies.
The motor(s) with higher power to weight ratio, will have much more effect on speed and efficiency than any marginal advantage gained from shaving a few ounces off spinning weight.
Here's a pair of Race Lites on an Ebay auction that ends tonight;
