The WTB CZR Carbon i30 is WTB's flagship 29-inch carbon rim, built specifically for riders who want the feel of premium carbon without the fragility anxiety. The 30mm internal width is dialed for 2.4 to 2.6-inch tires, and third-party lab tests showed these rims are laterally stiffer and more impact resistant than the competition in the same weight class. At around 484 grams per rim, they hit a sweet spot between trail-tough durability and the snappy, compliant ride feel that carbon does better than anything else.
WTB packed the CZR i30 with serious engineering: reinforced spoke beds, 4D angled spoke hole drilling, and a 5mm asymmetric spoke offset work together to equalize spoke tension and keep the wheel true over the long haul. The hookless bead design lets WTB put more material exactly where impacts hit hardest, and the integrated Solid Strip in the TCS 2.0 tubeless system protects the seal even if a spoke breaks mid-ride.
Multiple real-world reviewers across six-month-plus test periods report these rims staying straight and true through bike park laps on lava rock trails, enduro stages, and big-mile pedals. The CZR i30 is backed by WTB's Ride With Confidence Guarantee: break a rim while riding as the original owner, and WTB replaces it free, no questions asked.
Punch into a rock garden at full send and you will feel the difference a stiff, compliant carbon rim makes under you. Whether you are building up a dream enduro rig or upgrading worn-out alloy hoops on your trail bike, the CZR i30 gives you that confidence-inspiring locked-in feel without the fear of binning an expensive rim, because WTB literally replaces it for free if you do. This one is made for riders who ride hard, ride often, and are done babying their gear.
