HTZ i27 Rim
TCS (Tubeless Compatible System) is our industry-leading tubeless rim/tire system designed to international ETRTO and ISO standards.
6069 is the perfect aluminum alloy for bicycle rims due to its high tensile and fatigue strength, minimal weight, and excellent anti-corrosion properties.
Spoke holes are drilled at an angle to match the natural spoke path between a rim and hub. Eliminates binding and lateral loading of the nipples to increase wheel durability.
Rim ends are hydraulically pressed over an extruded aluminum insert that matches the inner cavity of the rim and is further reinforced by industrial epoxy.
Asymmetrically offset spoke holes create a stronger wheel by placing the holes more in line with the center of the hub and more evenly distributing spoke tension.
Vertical support within the inner rim cavity that drastically increases the strength and rigidity of our toughest rims.
Sloped rim valley allows the bead of the tire to easily and smoothly move into place during installation and inflation.
Installed between the rim and tubeless tape to prevent tape from sagging at each spoke hole and make tire inflation easier while also preventing puncture from a broken spoke.
SPECIFICATIONS: (Max spoke tension range: 110-120KgF)

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.
All of our alloy rims are best paired 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.
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. HTZ i27 rim requires 32mm TCS Tubeless Tape).
Asymmetrical rims feature a "short" and "long" side. It is helpful to always mount both sides of the tire onto the rim on the "short side" of the rim. The short side of the rim provides the shortest distance between the rim leg/bead and the valley of the rim. Once the first tire bead is completely on the rim, it can be pulled over the rubber portion of the valve and positioned at the deepest part of the rim valley. The other side of the tire can then be installed onto the rim with the least amount of resistance.
