WTB KOM Tough i25 TCS Rim - 29" is a hard-use 29er mountain bike rim built for riders who prioritize durability, predictable tire support, and dependable tubeless performance across enduro, aggressive trail riding, and loaded bikepacking. Its AL 6069 extrusion and reinforced internal shaping are tuned to handle repeated impacts and high spoke tensions without turning the rim into an anchor.
i25 (25mm internal width) - Provides stable tire support for modern trail and enduro setups, improving cornering feel and reducing tire roll compared to narrower rims
AL 6069 Alloy Construction - Tough, impact-resistant rim material that balances long-term durability with sensible weight for real-world riding
Evolved I-Beam Reinforcement (Dual Support Beams) - Increases rim stiffness and strength for aggressive riding and heavier bikepacking loads
4D Angled Spoke Drilling - Helps reduce spoke/nipple binding and lateral loading while spreading tension over a larger area for more consistent builds
TCS 2.0 Tubeless System - Designed for a more robust, easier-to-set-up tubeless interface and dependable sealing on demanding terrain
Solid Strip Channel + CVX Spoke Bed - Recessed center channel supports the Solid Strip to prevent tape sag at spoke holes; CVX geometry strengthens the spoke bed and increases nipple contact area to better distribute load
Setup Note - TCS 2.0 rims require WTB TCS tape applied on top of the Solid Strip
