WTB KOM i40 27.5

Wide trail rims that change the way you ride with thickness

The KOM Tough i40 is WTB's durable wide rim for hard trails, enduro, and even bikepacking.
It is the most volume-oriented model in the series, designed to be "bumped and used".

The material used is high-strength 6069 aluminum for both impact resistance and weight balance. In addition, the internal Dual I-Beam construction increases the rigidity and durability of the entire rim, providing a solid and stable feel even on rocky or rough surfaces.

The wide design with an inner width of 40mm is a good match for 2.8 to 3.0 inch class plus tires. The tire's volume is maximized to prevent swaying even at low pressure, providing high traction and a secure driving feel.

WTB's unique TCS 2.0 + Solid Strip construction makes tubeless setup easy and reliable. From everyday trail riding to extreme races and long distance rides with luggage, you can use this bike with confidence in any situation.
