I think these are the lightest off the shelf 29er wheels.
No Tubes Race Gold rims
No Tubes 3.30Ti hubs
DT revolution spokes
Crazy light, 1300g tubeless compatible.
A few small dings around the rims, holding air absolutely fine. Hubs are really smooth.
Comes with QR front/rear AND 15mm/142x12mm adapters
