Precision engineering brings the new Z1 Hubs to the next level. Larger TFT bearings, wider flange-to-flange placement, tool-free end caps with non-contact labyrinth design, hard-anodized dura-aluminum axle, the Z1 hubset has excellent functionality and unparalleled aesthetics, and is user-friendly. With all excessive spoke-hole side openings eliminated, the new Z1 hub shell not only looks elegant but also holds spokes much more securely.
