WTB KOM Light Rims

WTB's lightest alloy rims, the KOM Light family combines high-end performance and proven tubeless dependability to create an affordable rim attainable by all. KOM Light rims employ an open cavity design to make them sprightly enough for 200 miles of gravel, while strong 6069 aluminum alloy also make them 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.

Usage: Cross-Country / Trail

Features:

• OPEN-CAVITY DESIGN
  Open-cavity rim profile eliminates unnecessary weight while also reducing radial stiffness to create a smoother ride. Open-cavity rims are the top choice of drop bar and XC riders wanting to minimize weight while also improving rim compliance for less overall body fatigue at the end of a long day.
• DEPENDABLE 6069 ALLOY
  Many years of rim development and success have confirmed 6069 to be the perfect aluminum alloy blend for mountain bike rims. Our extensive testing shows other 6000-series alloy to be less ding-resistant, while stiffer 7000-series alloys result in a harsher ride feel and tend to increase pinch flats.
• 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 longterm durability of both the spoke and nipple.
• TCS SOLID STRIP
  Durable nylon strip that lies between the rim and tubeless tape to prevent tubeless tape from pushing into the spoke holes and ensures a smooth interface between the 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.
• 30MM INNER RIM WIDTH
  Enduro and aggressive trail riders across the globe have adopted 30mm as the go-to size for tires in the most common widths of 2.4-2.5". Most trail and enduro tires are now designed to be installed on a 30mm rim and doing so will optimize the air volume, sidewall support and tire profile of those tires. As XC becomes more aggressive and companies offer wider XC tires, these lightweight 30mm rims are also an excellent choice for XC riders who prioritize confidence over shaving grams.
• TCS (TUBELESS COMPATIBLE SYSTEM)
  TCS (Tubeless Compatible System) is our standardized tubeless system designed to meet international ETRTO standards and deliver unbeatable tubeless performance and reliability. TCS components reduce weight, increase traction, virtually eliminate flats and has established itself as the most dependable tubeless system available. Our TCS system includes tires, rims, tape, sealant and valves to provide a comprehensive package of unrivaled tubeless performance and reliability.

FAQs:

• HOW DOES RIM WIDTH AFFECT TIRE VOLUME AND PROFILE?
  Wider rims will cause a tire to also have a wider width, with more air volume within the tire and a flatter tire tread profile than designed for. As a general rule of thumb, a 2mm increase or decrease of inner rim width will result in a tire section width increase or decrease of 1mm. For example, our Nano 40 tire has a tire section width of 40mm on a 21mm inner rim width, however it will have a tire section width of 41mm on a 23mm inner rim width.
• WHICH TUBELESS VALVE LENGTH IS BEST FOR THIS RIM?
  All of our alloy rims work great with a 34mm valve stem. If you are using a deeper dish rim, like our CZR i23 rim, then we recommend the 46mm long valve stem. CZR i30 rims accept either length of valve.
• WHICH WIDTH OF TCS TAPE SHOULD I USE TO SET THIS RIM UP TUBELESS?
  WTB recommends using tape that is 5mm wider than the inner rim width. All WTB rims have the inner rim width listed in the name (i.e. KOM Light i30 rim requires 35mm TCS Tubeless Tape).
