CZR i30 Carbon Rim

CZR i30 rims were designed to handle it all, which is why they feature a strategically reinforced carbon layup, 5mm of asymmetric spoke offset, reinforced spoke beds, a hookless bead and Solid Strip integration. The enduro-approved 30mm inner rim width optimizes the tire volume and profile of 2.4-2.6" tires, which allows riders to run lower tire pressures which translates to improved traction and comfort.

Solid Strip & TCS Tape

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 internal with offset asym profile

Asymmetrically offset spoke holes help equalize the spoke tension of a wheel build, while the symmetrical outer profile distributes impact forces throughout the entire rim rather than absorbing them by one side more than the other. CZR i30 rims feature asymmetrical spoke offset of 5mm. Pairing the 30mm inner rim width with a 2.4-2.6" tire increases tire volume and sidewall support compared to traditionally narrower rims. The increased volume also allows riders to run lower tire pressures which translates to improved traction and comfort.

3-cross lacing and nipples

Too many companies are trying to save weight by offering "enduro" wheels with 2-cross lacing patterns and inadequate alloy nipples. While those are suitable for XC and light trail usage, there's no replacement for the longterm reliability of a 3-cross lacing pattern with our standard nipples holding it all together.

Frequency Hub

The world’s best carbon rims deserved to be paired with high-quality hubs that further improve the performance of a lightweight, dependable carbon wheelset. Frequency hubs feature a low-drag, 6-pawl design that alternates contact between two sets of 3-pawl groupings to provide a responsive 5 degrees of freehub engagement.

Heavy Duty Pawl Springs

CZR i30 wheels feature heavy-duty pawl springs that engage with greater force to counteract the additional torque caused by sudden cranking on steep trails. We also offer a Light Pawl-Spring Kit that can be purchased separately for CZR i30 riders who prefer a quieter hub with lighter pawl engagement.

PRODUCT TECHNOLOGY

TCS (Tubeless Compatible System) is our industry-leading tubeless rim/tire system designed to international ETRTO and ISO standards.

WTB carbon components are designed to provide a perfect blend of stiffness and compliance while also proving to be nearly indestructible.

Additional carbon at each spoke bed improves overall rim strength and durability while also minimizing weight in areas where less strength, and therefore material, is needed.

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.

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.

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.

Freehub ratchet system quickly alternates between two groups of three pawls each to provide quick engagement and trusted durability.

Why Choose CZR i30?

CZR i30 carbon wheels are for riders who demand a carbon wheel that won't let them down. CZR i30 wheels were designed to handle it all, which is why they feature a strategically fortified carbon layup, reinforced spoke beds, and are hand-built using double-butted spokes, brass nipples and our high-engagement Frequency hubs that use top-tier bearings and oversized freehub seals to establish themselves as wheels that simply won’t quit. We even sent the rims to an unbiased third-party lab to conduct destructive testing against what we considered to be the best carbon rims available during CZR development. In the end, our CZR i30 rims proved to be 10% more impact resistant than their direct competition.

Ride With Confidence Guarantee

If you break our CZR carbon rim while riding, we'll send you one for free. No exceptions. Didn't see that sharp rock until you were mid-air? Was the huck-to-flat a little flatter than you anticipated? Do you simply ride like a freight train without brakes? As long as you are the original owner and were riding your bike when it happened, we'll replace it for free. Your friends may judge for your poor line choice, but we won't. We also provide the option for us to rebuild the wheel and send it back to you with fresh spokes and nipples.

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.

15MM END CAPS ON FREQUENCY HUBS?

All CZR i30 front wheels feature hubs with 15mm end caps, but CZR i23 front wheels are assembled using Frequency hubs with 12x100mm front wheel spacing. However, we also sell a 15mm end cap kit on our Replacement Hub Parts page for riders with forks that require the use of a 15mm axle, such as Lauf forks. Swapping the end caps does not require any special tools.

WHY DO CZR i23 WHEELS HAVE A HOOKED BEAD WHILE CZR i30 ARE HOOKLESS?

CZR i23 rims feature a hooked bead because doing so provides a more dependable connection between the tire and rim when running a tire at the higher air pressures that are common with adventure road and gravel riding. CZR i30 rims feature a hookless bead because the smooth bead surface allows for more material to be used in an area when strength is incredibly important. Both CZR i23 and CZR i30 rims are compatible with any tires that comply with ETRTO standards.

ARE THERE TRICKS TO INSTALLING A TIRE ON AN ASYMMETRICAL RIM?

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.
