Giant SLR1 50 DB 28" rear wheel, 12x142 mm, CL, Shimano HG lockring
SLR 1 50 Disc WheelSystem braided wheels designed for versatile use deliver low weight, excellent aerodynamic efficiency and top power transmission. 50 mm high rims with an aerodynamic profile ensure excellent efficiency on straight sections and dynamic ride quality in hills. Hookless rims with a larger internal width offer more support for wider tires along with increased sidewall stiffness for better grip and cornering.
Features
- 50 mm high hookless aero rims proven by wind tunnel testing provide maximum aerodynamic advantage
- high tensile carbon fibers are placed only in the most important places to ensure optimal stiffness and at the same time a light weight that is the best in its class
- hookless rim construction saves weight and creates a larger 22.4mm internal rim width for more actual tire contact area, resulting in better traction and compliance.
- rim bead with a thickness of up to 3.8 mm on each side for increased rigidity and greater support for better cornering
- Dynamic Balanced Lacing (DBL) technology creates a stiffer and more efficient stringer as the wider hub flange increases the angle of the spokes for superior power transfer
- low-friction hubs with precision-machined internals eliminate excessive bearing stress, reducing bearing friction, reducing rolling resistance and minimizing power losses
