Are you looking for a rim that can handle the hardest impacts, rocky sections, and aggressive riding on technical terrain without batting an eye? The WTB KOM Tough i35 is engineered precisely for these moments. The “Tough” name says it all—this rim was designed to withstand extreme loads in enduro, gravity disciplines, demanding trail riding, and even on heavy e-bikes.
With an inner width of 35 mm, this rim is the ideal foundation for modern wide tires (plus-sized), providing them with perfect stability even when riding at low pressure.
Who is it for?
This rim is the obvious choice for riders who don’t want to deal with truing their wheels after every weekend at the bike park. Whether you’re building new wheels for an enduro bike, a hardcore trail bike, or need uncompromising durability for your e-MTB, the KOM Tough i35 won’t let you down.
- Dual-Chamber Design: The KOM Tough features internal reinforcements that dramatically increase the rim's torsional stiffness and its resistance to hard impacts and punctures.
- TCS 2.0 Tubeless System: Legendary tubeless technology from WTB. A special recessed channel (Solid Strip) in the center of the rim prevents the tubeless tape from buckling into the nipple holes, making installation easier and ensuring a perfect seal.
- High-quality aluminum alloy: Made from a super-strong AL 6069 series aluminum alloy, which offers the best balance between weight, durability, and fatigue life.
- Support for wide tires: The 35 mm internal width prevents the tires from "biting" during sharp turns and allows you to take full advantage of the grip offered by wide tires (ideal for tires 2.4" to 2.8" wide).
