Product Description
Our flagship CZR i23 carbon rims minimize rotational weight so you can break away early and stay ahead of the pack. Fine-tuned carbon compliance makes you feel at one with the terrain while also reducing rider fatigue throughout long rides. Reinforced spoke holes increase reliability and allow grams to be shaved elsewhere, while subdued decals provide a svelte look that matches their scant weight. CZR i23 is the gravel rim of choice if you're looking for the best strength-to-weight ratio for big gravel days.
Usage: Adventure Road • Gravel • Cross-Country

1
Reinforced Spoke Beds
Additional carbon thickness around each spoke bed improves overall rim strength and durability while also minimizing weight in areas where less strength, and therefore material, is needed. CZR i23 rims feature 3mm of asymmetrical spoke offset to help equalize spoke tension on both sides of a built wheel and provide a stronger overall wheel.
2
23mm inner width
Gravel bikes with tires ranging from 36-45mm are best suited for the 23mm inner rim width of our CZR i23 rims. This strategically chosen width provides the most optimal air volume and sidewall support for the widest range of gravel tires without adding the unnecessary weight of a wider rim.
3
Weight-Optimized Layup
Designed to minimize weight while blending stiffness and compliance to maximize power transfer and increase comfort during the longest rides of the year. Carbon thickness was fine-tuned throughout the CZR i23 rim to reduce weight, improve radial compliance, reduce rider fatigue and increase overall comfort.
4
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.
5
24mm section depth
CZR i23 rims feature a 24mm section depth to maximize energy transfer, reduce weight, improve vertical compliance, and reduce rider fatigue while a hooked bead also improves tire retention with high pressure adventure road and gravel tires.
Why Choose CZR?
CZR carbon rims provide an unbeatable strength-to-weight ratio. Reinforced spoke beds, proven 4D angled spoke holes and an asymmetrical design provide all the necessary ingredients for an incredibly durable carbon rim. Add in the Solid Strip integration of our TCS system and you now have a system that is not only easier to set up tubeless, but also nearly impervious to losing pressure in the event of a broken spoke. We even did third-party testing against the competition, and found CZR i23 rims to be laterally stiffer and more impact resistant to those within the same weight category. To be precise, our CZR i23 rims proved to be 38% 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 have quite enough pressure in your tires for that surprise stretch of chunky gravel? Didn't see the softball-sized rock until it was a bit too late? Did your gravel ride accidentally end up on a downhill track? 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.
