Using an I-Beam construction to increase its strength, the WTB KOM Tough i25 model keeps super stiff and responsive and is the perfect starting point if you want to build a gravity or enduro wheel that can withstand lots of punishment. WTBs lightest alloy rims, the KOM Light family combines high-end performance and proven tubeless dependability to create an affordable rim attainable by all. The WTB KOM Tough i25 rim employs an open cavity design to make it sprightly enough for 200 miles of gravel, while strong 6069 aluminium alloy also makes it resilient enough to endure daily hammering on your trail bike. Choose KOM Light when you're looking for high-end performance at a low-key price. WTB's unique Solid Strip integration also ensures it will be the easiest to mount and most reliable tubeless rim you've ever owned. KOM Tough has been 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. Additional Features: Dual I-Beam construction increases strength and stiffness Extruded from AL 6069 for durability and reasonable weight Updated spoke bed provides a more congruent interface between nipple and rim TCS 2.0 rims deliver WTB's easiest to mount and most reliable tubeless system WTB Solid Strip is included with the rim and provides a smooth surface between tyre and rim. It also prevents a broken spoke from puncturing the tubeless system and losing air TCS tape is also required for tubeless setup (sold separetely) Technologies: Universal Standard Tubeless (UST) Ready: The UST concept improves traction, control and comfort while reducing inertia and flats. TCS 2.0 Technology: This refined version of the “Tubeless Compatible System” offers the same high performance, lightweight mountain bike rim structure, but is now easier to install and more dependable. Dual I-Beam Support: Two vertical supports within the inner cavity drastically increase the strength and lateral stiffness of our KOM Tough rims. These additional reinforcements counteract spoke loads, which improves stiffness and minimizes deflection in rocky, unpredictable terrain. 4D Angled Spoke Holes: Drilling spoke holes at an angle eliminates binding and lateral loading of the spoke and nipple interface. It also allows spoke tension to be more evenly dispersed on the nipple rather than loading one side more than the other. Allowing the spoke to depart the rim at a natural angle increases the long-term durability of both the spoke and nipple.
This gravel-ready rim features an asymmetrical carbon build that allows it to deliver minimal rotational weight and fine-tuned compliance to make you feel at one with the terrain. WTB has also put this model through a series of lab tests and found that its CZR rim is lighter overall, more impact resistant, and laterally stiffer while remaining vertically compliant. After two years of development, this durable rim offers excellent reliability, wherever your next gravel bike adventure leads you. Gravel Bike Rim with Tubeless TCS 2.0 Technology WTB has equipped this gravel bike rim with its renowned TCS 2.0 technology, which provides a more robust, easily installed, and dependable tubeless system. A recessed channel along its centre allows for the installation of the updated Solid Strip, which prevents tubeless tape from sagging at the spoke holes and results in a smooth, consistent interface between the tyre and rim. Installation of the stout Solid Strip allows for more pliable, and easy to install, TCS Tape to provide the airtight seal needed for a tubeless system. This means that riders will enjoy tubeless benefits such as the ability to run lower air pressure for greater stability on rough terrain, increased comfort and less chances of punctures or flats. Additional Item Top Features: Spoke Beds: Reinforced with proven 4D angled spoke hole drilling Max Spoke Tension Range: 110-120KgF Single or Pair: Single Tubeless Tape Width: 28mm Technologies: Reinforced spoke beds, proven 4D angled spoke hole drilling and an asymmetrical design…all the necessary ingredients of an incredibly durable rim. 23mm internal rim width for the gravel-centric. When compared to the competition, WTB lab tests proved its CZR carbon rims to be lighter overall, more impact resistant, and laterally stiffer while remaining vertically compliant. To be precise, its CZR i23 rims were 38% more impact resistant than their direct competition. TCS 2.0 Technology: TCS 2.0 introduces a more robust, easily installed, and dependable tubeless system. A recessed channel along the centre of TCS 2.0 rims allows installation of the updated Solid Strip, which prevents tubeless tape from sagging at the spoke holes and results in a smooth, consistent interface between the tyre and rim.

This gravel bike tyre features WTB's Dual DNA compound which blends two high-quality rubber compounds together for superior rolling performance. Its short-knob centre tread cuts down on rolling resistance, while still providing enough bite for out-of-the-saddle traction. In addition, its centre and intermediate knobs are slightly taller than those of the Riddler thereby increasing tyre lifespan without negatively affecting rolling efficiency. Tall, toothy outer lugs ensure your favourite gravel descent doesn't unravel in the final corner, while single-ply 120tpi casing provides dependable protection at a minimal weight. Speaking for itself, Raddler is the radder version of WTB's famed Riddler tread pattern. It combines the expeditious efficiency of a short-knob centreline with get-rad traction of chunky outer knobs. Let’s call it a semi-slick, but one designed to increase confidence while you’re pushing the limits of gravel. Raddler is an excellent choice for loose terrain where traction takes priority, but efficiency is never far behind. Lean it over, take the inside line, brake late and stay pinned with the Raddler. SG2 Puncture Protection These tyres are available with WTB's SG2 Puncture Protection, which is a lightweight nylon insert that provides bead-to-bead coverage and ensures every area of the tyre is defended against slashes and punctures. As events become progressively rougher and cyclists pedal farther, gravel gets tougher. It only makes sense for gravel tyres to become tougher as well. Technologies: Dual DNA Compound: Two rubber compounds. The centerline tread features a firmer rubber compound that rolls fast and resists tread wear while the side knobs are composed of softer, slower-rebounding rubber to improve control and grip. All Dual DNA tyres fall within the Fast Rolling category. SG2 Puncture Protection: Nylon fibres have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibres and minimises weight. Protected SG2 gravel tyres feature a 120tpi casing, which improves suppleness compared to a traditional 60tpi tyre. SG2 was specifically designed to be a puncture protection layer, but it also improves air retention and eliminates seeping at the sidewall. Tyre Pressure Information: WTB's tyre pressure recommendations have changed over time due to further developments in technology. Riders may always reference the markings on their tyres for allowed pressures ranges, but WTB calculate pressure recommendations based on an average rider weight of 160-180 lbs and suggest increasing the minimum recommended pressure by 2-3psi for every additional 10 lbs of rider weight. Never exceed the maximum tyre pressure marked on a tyre. Manufacturer's Part Numbers: W010-0850 Black 40mm 700c W010-0851 Black 44mm 700c
