WTB’s had carbon rims before but they were nothing like their new CZR rims. These rims are designed with a bit of flex to help you maintain trail connectivity, have reinforced spoke holes, utilize TCS 2.0 tubeless technology, and are available in i23 and i30 inner widths for gravel or MTB riding.

Specs:
-Reinforced spoke beds, proven 4D angled spoke hole drilling and an asymmetrical design…all the necessary ingredients of an incredibly durable rim.
-Two internal width options… 23mm for the gravel-centric and 30mm for the mountain-focused.
-When compared to the competition, lab tests proved our CZR carbon rims to be overall lighter, stiffer and more impact resistant. To be precise, our CZR i23 rims were 38% more impact resistance than their direct competition while our CZR i30 rims were 10% more impact resistant.
-Original owner benefits from a Limited Lifetime Warranty against manufacturer defects in additional to a No-Questions-Asked crash replacement policy which offers a replacement rim at 50% off MSRP.
-Retail $569.95
