The all-new SLR 0 WheelSystem offer maximum all-day efficiency for climbing, sprinting, and descending. With wide and durable hookless rims, the SLR 0 40 offers confidence-inspiring handling, all at a super-light weight.

Features
Hookless rim design enhances durability and allows a wider inner rim width without adding weight.
Optimized carbon layup uses high tensile strength carbon fiber at key stress points for stiffness and lightweight performance.
Wind-tunnel-proven 40mm hookless rim profile delivers aerodynamic advantage.
Dynamic Balanced Lacing (DBL) technology creates a stiffer, more efficient wheel with superior power transfer. Enlarged DBL hub flanges increase spoke bracing angles, boosting torsional and lateral stiffness.
Wider 2.8mm rim bead width improves rim bead stiffness and tire support during cornering.
Designed for modern high-volume road tires, the 22.4mm inner rim width increases the tire contact patch for improved traction, impact absorption, and ride comfort.
Giant low-friction hub with precision-machined internals reduces bearing load, friction, and rolling resistance for minimized power loss.
High tensile-strength aero carbon spokes reduce lateral flex, enhance acceleration and climbing efficiency, and feature an aero profile for excellent stability in crosswinds at minimal weight.
