KOM Tough i30 TCS Rim - 27.5"

WTB KOM Tough i30 TCS Rim - 27.5" is a hard-use aluminum mountain bike rim built for riders who prioritize reliability under impact loads and heavy packing. The i30 profile targets modern trail, enduro, and bikepacking tire volumes, while WTB’s reinforced rim architecture focuses on spoke-bed strength, consistent tensioning, and dependable tubeless setup for real-world abuse.

• AL 6069 aluminum extrusion - chosen for a durability-focused rim build while keeping weight appropriate for aggressive trail and loaded riding
• I-Beam rim construction with dual support beams - increases stiffness and structural support where rims typically take hits and fatigue
• 4D angled spoke drilling - reduces spoke/nipple binding and lateral loading, helping tension distribute more evenly for longer-lasting wheel builds
• Patented CVX spoke-bed shaping - reinforces the spoke bed by placing material where it’s needed, while increasing nipple-to-rim contact area to better spread load
• TCS 2.0 tubeless-ready interface - designed for easier tire installation and a more robust, dependable tubeless seal compared to traditional rim profiles
• Solid Strip channel (TCS 2.0) - creates a smoother base over spoke holes to prevent tubeless tape sag; requires TCS tape applied over the Solid Strip for proper setup
