Extralite CyberRear SP-2+ Road Rear Hub

$549.00
Availability: Out of stock

The Extralite CyberRear SP-2 Road Hub refines one of the world’s lightest rear hub platforms with upgraded 2.8 mm straight-pull spoke holes, ensuring improved fit for high-tension aero or reinforced spokes while maintaining the same sub-135 g weight.

CNC-machined in Italy from 7075 TXX aluminum with a Grade 5 titanium freehub, the SP-2 employs a dual-pawl 32-tooth drive ring for quick engagement and efficient power transfer. The straight-pull flange geometry optimizes spoke tension balance and reduces fatigue, while Extralite’s Micro-Tuner preload system allows precise bearing adjustment.

Available with ceramic bearing upgrades (HDC or XD15) and freehubs for Shimano / SRAM 11-speed, SRAM XDR, and Campagnolo N3W, the SP-2 continues Extralite’s pursuit of absolute minimalism and flawless function.

SERVICE

Due to the lightweight construction of Extralite hubs, it is recommended that service be performed at frequent intervals to ensure proper function and the longest possible wear life of the internal components. Detailed service instructions can be found here. We recommend Extralite's Alugrease or Buzzy's Slick Honey for proper and effective lubrication of the seals and freehub mechanism.
