The SLR 1 50 Disc WheelSystem combines aerodynamic efficiency and minimized power loss in a lightweight package designed for versatile road performance. The SLR 1 50 features 50mm aero rim profiles for efficiency on the flats and a dynamic ride quality on hillier roads. Hookless rims with a broad inner width offer greater support for high-volume tires along with enhanced sidewall stiffness for better grip and cornering.FEATURESWind-tunnel-proven 50mm Hookless Aero Rim Profile provides a maximum aerodynamic advantageHigh tensile strength carbon fiber is placed at only the most crucial points to provide optimal stiffness and class-leading weightHookless rim design saves weight and creates a broad 22.4mm inner rim width for increased actual tire contact patch, resulting in better traction and complianceA thick rim bead of up to 3.8mm on each side enhances rim bead stiffness, offering increased support for better corneringDynamic Balanced Lacing (DBL) technology makes a stiffer, more efficient wheel as a wider hub flange increases spoke bracing angles for outstanding power transmissionLow friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance and minimizing power lossSPECIFICATIONS FRONTRim Material: CarbonRim Type: Hookless ClincherTubeless: Giant Tubeless System (rim tape and valve kit included)Suggested Tire Size: 700 x 25C 700 x 32CRim Height: 50mmRim Outer Width: 30mmRim Inner Width: 22.4mmETRTO622-22Front Hub: Low Friction Hub, CenterlockBearing: Sealed CartridgeFront Axle:100x12 Thru AxleSpokes(Front): SAPIM CX-RayLacing(Front): 24H, DBL DiscNippleType: AlloyWarranty: 2 yearsSPECIFICATIONS REARRim Material: CarbonRim Type: Hookless ClincherTubeless: Giant Tubeless System (rim tape and valve kit included)Suggested Tire Size: 700 x 25C 700 x 32CRim Height: 50mmRim Outer Width: 30mmRim Inner Width: 22.4mmETRTO622-22Rear Hub: Low Friction Hub, 30 Tooth Ratchet Driver, CenterlockHub Compatibility: Shimano HGBearing: Sealed CartridgeRear Axle:142x12 Thru AxleSpokes: (Rear) SAPIM CX-RayLacing: (Rear) 24H, DBL DiscNippleType: AlloyWarranty: 2 yearsWeight(Pair): 1518g, (Front) 703g, (Rear) 815gWheelSystem Weight Limit: 285 lbs / 129 kg
