KOM Tough i40 29" TCS 2.0 Rim w/ CVX

WTB KOM Tough i40 29" TCS 2.0 rim with CVX is a wide-profile 29er rim built for riders who prioritize impact strength, reliable spoke support, and confidence-inspiring tubeless performance. Its reinforced structure and refined spoke bed geometry are designed to hold tension well, reduce stress at the spoke holes, and stay dependable under aggressive trail loads.

• Dual I-Beam construction - increases rim stiffness and strength for better resistance to hard impacts and rim deflection
• CVX spoke-hole technology - improves spoke/nipple alignment and reinforces the spoke hole area to help reduce localized fatigue
• AL 6069 alloy extrusion - durable rim material choice that balances toughness with practical weight for real-world trail use
• Updated spoke bed interface - creates a more congruent nipple-to-rim fit to support consistent tension and smoother wheel builds
• TCS 2.0 tubeless-ready bead - engineered for easier mounting and a more reliable tubeless seal when set up with appropriate tape and sealant
• WTB Solid Strip included - provides a smooth surface between tire and rim and helps protect the tubeless system if a broken spoke occurs

For tubeless setup, TCS tape is still required (in addition to sealant and a compatible tubeless tire).
