Extralite HyperCamber2 Rear Disc Hub

The HyperCamber2 is the latest iteration of Extralite's 29- and 27.5-specific rear disc hub. This edition features updated bearings, an improved polyurethane freehub seal, and a "twin life" hub shell that allows the floating clutch to be re-positioned after extreme wear.

The HyperCamber2 rear hub is one of the lightest disc hubs available for larger wheels. While its weight is minimal, its build strength is no slouch. The ultra-large drive side flange offers a 10% gain in spoke bracing angle, which builds a wheel that is very stiff laterally and is stronger than other hub designs. Adding to its strength are four bearings that rest upon its stout 17mm axle. Additional performance benefits include a 36 position engagement freehub body, which can withstand over a half-ton of chain pull. The hub body is 7075TXX aluminum anodized in black with laser-etched logos.

The HyperCamber2 is available in several options; with either a standard 135mm QR axle or a 142x12 axle, and either a Shimano 9/10 freehub or a Sram XD style freehub.
