The Extralite CyberRear SPD-3+ is Extralite’s ultralight straight-pull rear road disc hub, designed for premium disc brake wheel builds where low weight, fast engagement, and serviceability matter. Machined in Italy from high-strength 7075 aluminum with Grade 5 titanium components, it delivers a refined balance of minimal weight and long-term performance.
The straight-pull hub shell uses a cross-laced spoke layout with 2.8 mm spoke holes for improved spoke support and wheel stiffness. A 32-tooth dual-pawl freehub mechanism provides quick engagement, while Extralite’s Micro-Tuner bearing preload system allows precise adjustment for smooth, play-free rotation.
Available with stainless steel, HDC ceramic, or XD15 ceramic bearing options, the CyberRear SPD-3+ is built for custom road disc wheels where every detail is selected for efficiency, weight, and reliability.
Service & Maintenance
Regular inspection, cleaning, and lubrication help maintain smooth bearing performance and reliable freehub engagement. Extralite hubs are built with extremely close tolerances, making routine service especially important for long-term performance.
Detailed service instructions are available in the CyberRear SPD-3+ service manual.
For lubrication, we recommend Extralite Alugrease or Buzzy's Slick Honey.
Compatible Freehub Bodies
The CyberRear SPD-3+ accepts Extralite CyberRear freehub bodies for Shimano HG, SRAM XDR, Campagnolo 11 / 12-speed, and Campagnolo N3W cassette standards. Replacement freehub kits are available separately for drivetrain conversions or routine freehub service.
Wheel Building
The CyberRear SPD-3+ is designed for lightweight custom road disc wheels using straight-pull spokes. Proper spoke selection, tension balance, and lacing technique are critical for achieving the intended stiffness, durability, and ride quality.
