WTB CZR i30 MTB Wheels (Black) (6-Bolt) (Front) (29") (15 x 110/12 x 148mm)

From Performance Bike

CZR i30 wheels were designed to handle it all. The rims are made with a strategically reinforced carbon layup that and are hand built using double-butted spokes and brass nipples, featuring hubs with top-tier bearings and oversized freehub seals to establish themselves as wheels that simply won't quit.
