Unquestionably one of the finest producers of quality components for the discerning cyclist, Extralite is the go-to company for gram conscious builds. Responsible for some of the absolute lightest hubs available, Extralite is a company constantly pushing the envelope for what may be possible.
The insanely light CyberRear SPD tips the scale at a mere 144 grams, making it perhaps the lightest disc road hub available to date. Utilizing a 17 mm wide axle, the CyberRear SPD proves to not only be an incredibly handsome hub, but also a surprisingly stiff one. In an effort to shave as many grams as possible, while still creating a reliable road hub platform, Extralite chose to use a specially crafted 2 pawl road specific freehub body, mated to an oversized titanium ratchet ring. Doing away with the temperamental freehub bushing, Extralite has added a fourth bearing to the freehub body, making it not only more durable, but additionally much more smooth.
All Extralite components are proudly manufactured in Italy.
Due to the lightweight nature of the Extralite CyberRear SPD hub, it is imperative that a frequent service schedule be adhered to. Simple to perform, all service to the CyberRear SPD can be accomplished using basic hands tools. A detailed manual for service can be found here. We recommend Slick Honey for proper and effective lubrication of the seals and freehub mechanism.
