Ted - I'm surprised you think I glossed over my cassette. Maybe you are one of the members who views the group on your email client, making it almost impossible to follow a multipost thread? Anyway, the cassette is attached to the rear wheel, so I count it as part of section 2: Wheel set. There, in the post about the wheels, I explained exactly the cassette I'm using for the initial build: A vintage XTR 12-32 which weighs 240g. If I end up with $350 of Christmas money and find that a 38x32 is too high a low gear, perhaps I'll spring for a 1090 cassette. "Light and free" beats "ultralight and ultra-expensive" in my garage.
