Description
Lightweight and tough carbon trail rim
WTB / Double-TB's carbon rim CZR i30 is suitable for a wide range of applications from trail to enduro.
The CZR i30 is a high performance model that combines the high rigidity and suppleness that only carbon can offer.
Strategically designed carbon layup ensures lateral rigidity and radial compliance that absorbs impact moderately. It creates a stable riding feel with less burden on the body, even on rough surfaces, without going off line.
The wide design with an inner width of 30 mm is compatible with 2.4 to 2.6 inch tires and is designed to increase traction and comfort even at low pressure. In addition, the asymmetric construction optimizes spoke tension balance, improving durability and wheel rigidity.
The reinforced spoke holes and TCS 2.0 + Solid Strip construction also make tubeless setup easy and reliable. From hard trail riding to enduro racing, this carbon rim can be used with confidence.
