Z-WHEEL

AR1 WHEEL KIT FRONT / REAR TRAIL

SPECIFICATIONS:

- A wheel kit assembled with the same specifications as the AR1 WHEEL for competition bike.
- By combining Z-Wheel made R50 aluminum rim, ASTELIGHT HUB, and an Aluminum nipple spoke set, compared with stock, a light weight and high strength wheel is acheived.

[ Astelight HUB ]
By precision CNC machining, high-strength cylindrical aluminum to 1/10th in weight, the design emphasizes strength, light weight and a beautiful appearance.
[ R50Rim ]
R50 rim is racing specification for MX / ED race use. The rim uses A7050 T6 Aluminum to pursue a cross-sectional surface designed to balance contradictory conditions of strength versus weight.
[ Aluminum Nipple & Stainless Spoke ]
Z-WHEEL uses high strength aluminum nipples that provides weight reduction compared to stock steel nipples. Z-WHEEL uses high strength stainless steel spoke set which provides a balance of strength and reduced weight by increasing the wire diameter.
