Lightweight and durable MTB rim with UST Tubeless technology.

The Mavic XC 621 Disc is a versatile aluminum rim for fast cross-country and trail wheel builds. Its low weight and stable construction offer an excellent balance of efficiency, durability, and control.

Thanks to the proven UST Tubeless technology, the rim can be ridden tubeless. The special rim bed with integrated humps securely holds the tire bead in place and allows lower tire pressures for more grip, comfort, and puncture protection.
