Description
Simply put, WTB KOM Tough rims were built for bashing. An excellent choice for adventure gravel bikes, the WTB KOM Tough i25 rim is dependable for fully loaded touring or bikepacking.
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
