My son just installed the Stans/Chris King wheelset that I laced up for him on his new carbon Felt bike. Total weight on my semi-accurate fish scale was right at or maybe just a "tick" under 17 pounds. That's about a pound heavier than he was hopeing but still pretty good. Actually, considering he's using Dura Ace brifters and he doesn't have any really exotic components like a carbon crankset or aftermarket brakes, I'm thinking 17 pounds is realistic.
He's planning to take it out to Schulersberg hill tomorrow. Schulersberg has one section that, I'm told, is around 20% so that should be a pretty good test.
