WTB KOM Tough i25 Rim

Features

• Proven on the toughest tracks of the Enduro World Series, depended on for daily trail rides, and trusted while bikepacking in remote regions of the world
• 25 inner rim width is best suited for gravel bikes with 41–50 mm tires
• Dual I-Beam Support: 2 vertical supports within the inner cavity drastically increase the rim’s strength and lateral stiffness for aggressive riding
• These additional reinforcements counteract spoke loads, which improves stiffness and minimizes deflection in rocky, unpredictable terrain
• 4D angled spoke drilling eliminates binding and lateral loading, and disperses tension more evenly over a greater area
• Extruded from top-tier 6069 aluminum alloy for unbeatable durability at a reasonable weight
• Durable nylon TCS Solid Strip lies between the rim and tubeless tape to prevent the tape from pushing into the spoke holes, ensuring a smooth interface between tire and rim
• The smooth surface makes it easier to mount a tire by preventing air from escaping around the bead at each indent during inflation
• Solid Strip also protects the airtight system from puncture in the case of a broken spoke
• TCS (Tubeless Compatible System) is a standardized tubeless system designed by WTB to meet international ETRTO standards
• TCS components reduce weight, increase traction and virtually eliminate flats for a dependable tubeless system
