    Featuring hookless rim design and optimized carbon layup to ensure a robust yet lightweight structure, contemporary wider inner width, as well as low friction hubs offering low rolling resistance and Dynamic Balanced Lacing (DBL) technology to maintain maximum power efficiency, the SLR 1 42 Disc brings outstanding versatile performance at no compromise.


      • Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight
      • Optimized carbon layup features high tensile strength carbon fiber placed at the most crucial points to provide stiff and lightweight wheels
      • Low friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance and minimizing power loss
      • Dynamic Balanced Lacing (DBL) ensures spokes are set for optimal tension when pedaling, resulting in enhanced durability and transmission efficiency
      • The enlarged DBL hub flange increases spoke bracing angles, boosting overall torsional/transmission and lateral stiffness for better power transfer
      • 42mm deep all-round rim profile with an updated inner width offers better support for today’s higher volume road tires
