KOM Tough i35 TCS Rim - 27.5"

WTB KOM Tough i35 TCS Rim (27.5") is a wide, impact-ready aluminum MTB rim built for aggressive trail and enduro riding, plus the sustained loads of fully packed bikepacking. The i35 (35mm internal) profile better supports higher-volume tires for a more stable contact patch and improved sidewall support when pushing hard through corners or running lower pressures.

• AL 6069 alloy extrusion - prioritizes dent resistance and long-term durability without the weight penalty of overly thick rim walls
• I-Beam construction with dual support beams - reinforces the rim structure for higher stiffness and strength under hard hits and heavy loads
• 4D angled spoke drilling - reduces spoke/nipple binding, minimizes lateral loading, and spreads tension more evenly for more consistent wheel builds
• Patented CVX spoke-bed shaping - adds material where it matters and removes it where it doesn’t, increasing nipple contact area to better distribute load at the spoke bed
• TCS 2.0 tubeless-ready design - engineered for a more robust, easier-to-install tubeless setup with a dependable tire-to-rim interface
• Solid Strip channel (TCS 2.0) - supports the tubeless tape interface by preventing tape sag at spoke holes; TCS tape is applied on top of the Solid Strip
