The Dura-Ace WH-R9270-C60-HR-TL Wheelset by Shimano – For powerful pedalling
The Shimano WH-R9270 wheelset has 60 mm high carbon rims and is the perfect complement for your Dura-Ace R9200 road bike groupset with Center Lock disc brake. Its Direct-Engagement aluminium freehub provides increased drive efficiency, and is compatible with 12-speed cassettes only. The tubeless high-performance model with the additional designation ” HR” for ” High Rigidity” features enormous lateral stiffness, which makes it particularly suitable for powerful sprints. The rims have a jaw width of 21 mm for tyres up to 32 mm wide and are presented in the wind tunnel-proven D2 design. They are each fitted with 24 double butted stainless steel spokes, and a specific lacing pattern is used on both the front and rear wheel to balance the spoke tension. At the centre of the wheels rotate 12 mm thru-axle hubs with E-Thru technology for more torsion resistance. The stainless steel conical bearings are durable and easy to maintain.

Technology:
Cup and Cone Bearings
Angular contact ball bearings of the cup & cone type are superior to sealed cartridge bearings in terms of load carrying capacity, as they distribute lateral and vertical forces better, and thus run particularly smoothly and last a long time. They are also easier to adjust, maintain and replace.
E-Thru
E-Thru is a tool-free thru-axle system from Shimano that optimises the stiffness-to-weight ratio and ensures easy handling via its reliable internal cam mechanism. It is characterised by a high torsion resistance and thus also supports cornering at high speed. E-Thru thru-axle hubs and thru-axles are available in the corresponding over locknut dimensions for front and rear.
