The SLR 1 65 Disc WheelSystems are lightweight, aero carbon wheels that deliver premium aero gains to all riders. Featuring a 65mm deep rim profile with a contemporary 22.4mm inner width, SLR 1 65 WheelSystems not only provide aerodynamic benefits but also better support for todays higher volume tires. With hookless rim design and optimized carbon layup to ensure robust structure with minimal weight, as well as low friction hubs and Dynamic Balanced Lacing technology to maintain maximum power efficiency, the SLR 1 65 Disc offer riders maximum aero efficiency with no weight penalty.FEATURES:Hookless rim design enhances overall durability and offers a wider inner rim width without adding weightOptimized carbon layup features high tensile strength carbon fiber placed at the most crucial points to provide stiff, compliant and lightweight wheelsLow friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance and minimizing power lossDynamic Balanced Lacing (DBL) ensures spokes are set for optimal tension when pedaling, resulting in enhanced durability and transmission efficiencyThe enlarged DBL hub flange increases spoke bracing angles, boosting overall torsional/transmission and lateral stiffness for better power transfer65mm deep aero rim profile with a 22.4 inner width offers better support for todays higher volume road tires and minimizes aerodynamic lossSPECIFICATIONSRim Material: CarbonRim Type: Hookless ClincherTubeless: Giant Tubeless System(rim tape and valve kit included)Rim Height: 65mmRim Outer Width: 26mmRim Inner Width: 22.4mmETRTO: 622-22Rear Hub: Giant Low Friction Hub, Ratchet Driver 30T, CenterlockHub Compatibility: Shimano HG 11/12, SRAM 11Bearing: Sealed CartridgeRear Axle: 142x12 Thru AxleSpokes (Rear): SAPIM CX-RayLacing (Rear): 24H, DBL DiscNipple Type: AlloyWeight (Pair): 1639g
