DURA ACE 7850 CARBON/CLINCH RR

WH7850 CL carbon laminate wheel, designed to meet pro road race criteria
Clincher rim maintains high braking performance with standard brake pads
Low rim weight is achieved by reducing the alloy wall thickness from 1.3 mm down to 0.7 mm, then a patent pending 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 under high loads
20 rear stainless steel butted and bladed straight pull spokes with a 2x lacing pattern improve lateral and torsional rigidity
Elbow-less spokes make for a strong yet compliant wheel
High lateral rigidity is produced with a 3 mm offset asymmetric rim and wide flange spacing
Improved Freehub with quick pawl engagement (125% faster than previous Dura-Ace) for instant power transfer
Labyrinth double-contact sealing effectively shuts out water, mud and dirt without affecting rotational smoothness
Borozon treated bearing races - super mirror finish reduces friction
Cold forged, machined aluminium hub shell and oversized 7075 alloy axle combined with a titanium freewheel body keep the wheel weight to a minimum
8,9 and 10-speed compatible rear wheel
Supplied with Q/R skewer and wheel bag
