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.
