Thanks. They're customs - Kinlin XR270 (front) / 300 (back), Alchemy Elf/Orc hubs, 24/28h, CX-rays. They came in at 1460g. They were built by Ron Ruff at White Mtn Wheels. Mainly I wanted something durable yet as light as possible given my weight of around 200 lb, and something that looked good too. They haven't made me any faster, but I like them so far and they've stayed true for a few hundred miles over some pretty brutal roads.
