KOM Tough i40

Built for bashing, whether on a gravity shred sled or fully loaded bikepacking rig. KOM Tough rims are extruded from top-tier alloy to provide utmost durability at a reasonable weight. Our legendary I-Beam construction has evolved to further reinforce the rim with dual support beams that provide increased strength and stiffness for the world’s most aggressive riders. 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, KOM Tough rims are available in 25, 29, 35, 40 and 45mm widths to provide a burly rim for every usage and style of riding. FEATURES: TCS 2.0 creates a more robust, easily installed and dependable tubeless system.  A recessed channel along the center of TCS 2.0 rims allows installation of the all-new Solid Strip, which prevents tubeless tape from sagging at the spoke holes and results in a smooth, consistent interface between the tire and rim. 4D angled spoke drilling eliminates binding and lateral loading, and disperses tension more evenly over a greater area.  Disc-brake only.  REVIEWS:  NSMB -    USAGE:  Trail / Enduro SPECIFICATIONS:  (Max spoke  tension range: 110-120KgF)   Wheel Size Inner Width *Weight Hole Count ERD Rim Size Designation 27.5" 40mm 590g 32 568 40-584 29" 40mm 627g 32 606 40-622  *KOM Tough rims weighed with Solid Strip installed.
