All use Toray T1000 rims, BL100 54T ratchet ceramic hubs and CX-Ray spokes, so switching between road and gravel means keeping one platform: same engagement, same warranty, different depths.

Every ULT wheelset is hand-built and tension-balanced in our Xiamen facility, then tested for lateral and radial trueness before shipping. Rotor and cassette fitting is available at checkout, and free rim tape and tubeless valves are always included. If you race criteriums or road sportives, the 40–50R depths cover the full range; for gravel events, the 35–50G builds bring the same T1000 layup to loose surfaces.
