Or, what about upgrading tires instead of wheels. I just put new tires on my LHT. They are 300+ grams lighter and 1/4" narrower and I'm feeling downright speedy. I've been knocking minutes off my commute with the new tires. Almost 5 minutes on the first (uphill) section of my commute this AM. Last Friday my average speed to work was 13.1 mph. My average for January was in the low 11mph. bikerHen
I already have Michelin Pro Race tires...so I imagine they are pretty light
If I went with new wheels, they would be custom with better parts I'll try practicing hills and think about the wheels At 1755 grams my wheelset is 3.87 pounds..which seems like kind of a lot
