Key Features: WH-R9100 CL carbon clincher wheel, designed to meet pro road race criteria Full carbon / alloy 21 mm deep 20.8 mm wide rim Low rim weight is achieved by reducing the alloy wall thickness from 1.3 mm down to 0.7 mm, then a patented phosphoric acid anodizing process is used to bond the carbon fibre to the alloy giving an excellent combination of low weight, strength and rigidity Carbon reinforced spoke eyelets increase durability Alloy clincher rim maintains high braking performance with standard brake pads in all conditions 16 stainless steel butted (2.0-1.5-2.0) and bladed straight pull spokes Elbow-less spokes make for a strong yet compliant wheel High lateral rigidity is produced with a wide flange spacing Labyrinth double-contact sealing effectively shuts out water and dirt Alloy cone with integrated steel Borozon treated bearing races - super mirror finish reduces friction Quick and easy to maintain digital click bearing adjustment Cold forged, machined aluminium hub shell and oversized 7075 alloy axle keep the wheel weight to a minimum 700C clincher compatible Supplied with Q/R skewer Average weight 585 grams
