KOM Tough i30 TCS Rim - 29"

WTB KOM Tough i30 TCS Rim - 29" is a hard-use aluminum MTB rim built for riders who routinely push wheels into rock strikes, hard compressions, and heavy loads. Using AL 6069 alloy and WTB’s reinforced I-Beam profile with dual support beams, it targets long-term durability and rim stability for aggressive trail, enduro, and bikepacking builds.

Key design advantages for real-world riding

1. i30 internal width (29") - Supports modern trail tire volumes with a stable tire profile for predictable cornering and support under load
2. AL 6069 alloy construction - Chosen for impact resistance and fatigue strength where rim durability matters more than chasing minimal weight
3. Dual-beam I-Beam reinforcement - Increases rim stiffness and strength to help maintain wheel integrity through repeated hits and high spoke tensions
4. 4D angled spoke drilling - Reduces spoke/nipple binding and helps distribute tension more evenly across the spoke bed for a more consistent build
5. TCS 2.0 tubeless interface with Solid Strip channel - Creates a smoother base at spoke holes to help prevent tape sag and improve tubeless setup consistency
6. Patented CVX spoke-bed shaping - Adds material only where needed to strengthen the spoke bed and increase nipple-head contact area for better load distribution

Installation note: TCS 2.0 rims require WTB Solid Strip with TCS tape applied on top for tubeless setup.
