Details

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.

Assembly

We recommend that wheels with Extralite hubs be built by an experienced wheelbuilder. We are happy to provide this service, and can provide helpful suggestions in rim and spoke selections. Please contact us directly or submit a form for a custom wheelbuild here.

Service

Extralite hubs feature carefully designed rubber o-ring seals and lightweight ratcheting mechanisms which require frequent service to ensure long life and maximum performance. This service is easily performed with simple hand tools. An instruction manual for the HyperRear Disc hub is provided here: http://www.extralite.com/Manuals/HyperRear.pdf

Extralite strongly recommends the use of their Alugrease Super 1 when lubricating the HyperCamber's o-rings, bushings, and drive rings.
