Our lightest aluminum rims, the KOM Light family, combine high-end performance and proven tubeless reliability to create an affordable rim accessible to everyone. KOM Light rims utilize an open-cavity design to be lively enough for 200 miles of gravel, while the durable 6069 aluminum alloy makes them strong enough to withstand the daily abuse of a trail bike. Choose the KOM Light if you're looking for high-end performance at a low price. Application: Adventure Road / Gravel / Cyclocross TCS - TCS (Tubeless Compatible System) is our industry-leading tubeless rim and tire system, designed to international ETRTO and ISO standards. 4D Drilling - Spoke holes are drilled at an angle to match the natural spoke path between the rim and hub. This eliminates binding and lateral loading of the nipples, increasing wheel durability. ON RAMP - The inclined recess on the rim allows the tire bead to slide easily and smoothly into place during mounting and inflation. AL. 6069 - 6069 is the ideal aluminum alloy for bicycle rims due to its high tensile and fatigue strength, minimal weight and excellent anti-corrosion properties. SLEEVED - The rim ends are hydraulically pressed against an extruded aluminum insert that fits into the inner rim cavity and is further reinforced with an industrial epoxy resin. Double Wall - All WTB rims feature two separate layers of rim material for added strength. This design creates additional space between the tire and the spokes. SOLID STRIP - Mounted between the rim and the tubeless tape to prevent the tape from sagging at each spoke hole and to make it easier to inflate tires, as well as to prevent punctures caused by a broken spoke.
