The 38mm deep Kinlin XR-380 is Kinlin's deepest niobium-aluminum alloy rim and among the deepest aluminum rims available from any manufacturer. The XR-380's 38mm depth and 20mm width provides lateral stiffness, high-strength and durability.
The Kinlin XR-380 features a lightweight semi-deep aero rim section that weighs in at only 550 grams. The XR-380's 38mm depth dramatically increases cross-sectional stiffness, which allows reliable wheels to be built with low spoke counts.
