This third iteration of Extralite's road disc rear hub makes several notable improvements over the previous design while maintaining the same incredibly low weight of 146 grams for the Shimano freehub version. The non-drive side flange now uses a cross-laced straight pull design for hassle-free wheel building and spoke replacement (the SPD-2 used a radial spoke design which required removal of the axle for spoke installation). Additionally, the CNC profile has been reworked with improved spoke bracing angles for more equalized spoke tension, while allowing a higher maximum spoke tension.

The CyberRear SPD-3 is by far the best option available to build an incredibly lightweight road disc wheel. The straight-pull flanges will accommodate standard 14 gauge spokes, as well as Pillar's incredibly light X-Tra Lite Titanium 13 gauge spokes. The design of the spoke flanges increases the stiffness of the complete wheel for reduced lateral flex under hard efforts, and better braking response. Each Cyberhub is equipped with a convenient micro-tuner to allow perfect bearing preload adjustment for low bearing friction, and zero play at the rim.

The CyberRear's freehub system features dual pawls with a 32t engagement ring, with options for Shimano/Sram, Campagolo, and Sram XDR freehub bodies. This system is incredibly lightweight and strong, though Extralite does not recommend running gear ratios lower than 1:1.

Each CyberRear hub is expertly machined from military-grade 7075TX aluminum, with an attractive aesthetic that Extralite is known for. These hubs are specifically designed for use on road disc bikes only, and have been carefully engineered for this application with an impressive rider weight limit of 200 pounds. 

The CyberRear SPD-3 from Extralite is 100% manufactured in Italy.
