SURE FOOTED SPEED

The SLR 1 40 650b is WheelSystem built for smaller frame sizes and delivers quick acceleration, agile handling, and long-lasting efficiency—ideal for smaller riders who want top-tier road and gravel performance.

Features

  • 650b Rim Diameter - Optimized for smaller road and gravel frames
  • Hookless Rim Design – Enhances durability and offers a wider
    inner rim width without adding weight.
  • Optimized Carbon Layup – High-tensile-strength carbon fiber is strategically placed at critical points to provide a stiff yet lightweight wheel.
  • 40mm Hookless Rim Profile – Offers an added aerodynamic advantage.
  • Dynamic Balanced Lacing (DBL) Technology – Creates a stiffer, more efficient wheel with outstanding power transfer. The enlarged DBL hub flange increases spoke bracing angles, boosting overall torsional, transmission, and lateral stiffness for better power transfer.
  • 2.8mm Rim Bead Width – Enhances rim stiffness, providing better tire support during cornering.
  • 22.4mm Inner Rim Width – Designed for high-volume road tires, it increases the actual tire contact patch for better traction, impact absorption, and an improved ride feel.
  • Giant Low Friction Hub – Precision-machined internals reduce
    bearing friction, lower rolling resistance, and minimize power loss.
