Lightweight and robust MTB rim with UST Tubeless technology.

The Mavic XC 621 Disc is a versatile aluminum rim for fast cross-country and trail wheels. With its low weight and stable construction, it offers 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 secures the tire bead particularly well and allows for lower tire pressures for more grip, comfort, and puncture protection.

Made from 6061 aluminum and equipped with 32 spoke holes, the rim is ideal for durable MTB wheel builds for cross-country or trail use.

Highlights:

• UST Tubeless Technology: more grip and fewer punctures.
• Lightweight: only approx. 450 g – ideal for fast XC wheels.
• 21 mm internal width: suitable for modern XC and trail tires.
