The new SLR 1 50 Disc Wheel System 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. Hook less rims with a broad inner width offer greater support for high-volume tires along with enhanced sidewall stiffness for better grip and cornering.Hook less Technology:- Hook less rim design saves weight and creates a broad 22.4mm inner rim width for increased actual tire contact patch, resulting in better traction and complianceAero Efficiency:- Wind-tunnel-proven 50mm Hook less Aero Rim Profile provides a maximum aerodynamic advantageDynamic Balanced Lacing:- Dynamic 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:- Low friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance and minimizing power lossFeatures:- Wind-tunnel-proven 50mm Hook less Aero Rim Profile provides a maximum aerodynamic advantage- High tensile strength carbon fiber is placed at only the most crucial points to provide optimal stiffness and class-leading weight- Hook less rim design saves weight and creates a broad 22.4mm inner rim width for increased actual tire contact patch, resulting in better traction and compliance- A thick rim bead of up to 3.8mm on each side enhances rim bead stiffness, offering increased support for better cornering- Dynamic Balanced Lacing (DBL) technology makes a stiffer, more efficient wheel as a wider hub flange increases spoke bracing angles for outstanding power transmission- Low friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance and minimizing power lossSpecifications:- Rim Material: Carbon- Rim Type: Hook less Clincher- Tubeless: Giant Tubeless System (rim tape and valve kit included)- Suggested Tire Size: 700 x 25C – 700 x 32C- Rim Height: 50mm- Rim Outer Width: 30mm- Rim Inner Width: 22.4mm- ETRTO: 622-22- Rear Hub: Low Friction Hub, 30 Tooth Ratchet Driver, Center lock- Hub Compatibility: Shimano HG, SRAM XDR (XDR driver sold separately)- Bearing: Sealed Cartridge- Rear Axle: 142x12 Thru Axle- Spokes (Rear): SAPIM CX-Ray- Lacing (Rear): 24H, DBL Disc- Nipple: Type Alloy- Weight: (Rear) 815gTechnology:Hook less Rim Design:- Hook less rim design enhances overall durability, offers a wider inner rim width without adding extra weight and also helps create a more round tire shape providing superior grip and handling as well as added sidewall support when cornering. Additionally, without the rim hook to push the tire bead inward, hook less rim design offers a more seamless airflow between the tire and the sidewall of the rim, resulting in less drag and improved aero performance when compared to standard hook-type rims.Dynamic Balanced Lacing:- Since its introduction in 2015, Dynamic Balanced Lacing (DBL) has been the cornerstone of Giant Wheel Systems. DBL ensures that spokes are set for optimal tension when under dynamic load, resulting in enhanced durability and pedaling efficiency. The enlarged DBL hub flange also increases the spoke bracing angles, which boosts overall torsional/transmission and lateral stiffness for better power transfer and more stable sprinting.Low Friction Hub:- Giant uses precision machined internals to eliminate the power loss that occurs through the pressure from the hub internals on the bearings, reducing friction and minimizing rolling resistance.
