Extralite Cyber SPC-3+ Road Centerlock Disc Hubset

The Extralite Cyber SPC-3+ hubset represents the next evolution of ultralight road disc hubs, now optimized for Centerlock rotor mounting. Combining the CyberFront SPC-3+ (~61 g) and CyberRear SPC-3+ (~140–147 g depending on freehub), this hubset delivers unmatched stiffness-to-weight for elite road and gravel disc builds.

Machined in Italy from aerospace-grade 7075TXX aluminum and Grade 5 titanium, the SPC-3+ hubs feature cross-laced straight-pull flanges, Extralite’s signature Micro-Tuner preload system, and ceramic or stainless bearing options. Both hubs are EN-tested and approved for riders up to 200 lbs (90 kg).

Together, the pair weighs as little as ~214g, making the Cyber SPC-3+ hubset one of the lightest and most advanced Centerlock options on the market.

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.
