The CZR i30 wheels have been designed to handle the roughest terrain, so they feature a strategically reinforced carbon layer, reinforced spoke bed and are hand-spliced with double-butted spokes, brass nipples and high-quality Frequency hubs with top-tier bearings with perfect sealing.
Our CZR i30 rims have proven to be 10% more impact resistant than their direct competition in an independent lab test.
If you break our CZR carbon rim while riding and you are the first owner, we will replace it for free. No exceptions!
