The Dura-Ace WH-R9270-C60-HR-TL wheelset by Shimano including wheel bag


The Shimano WH-R9270 wheelset, here in the version with a wheel bag, has 60 mm deep carbon rims. It is the perfect complement for your Dura-Ace R9200 road bike groupset with centre 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 cup & cone bearings are durable and easy to maintain.

Technology:

D2 Rim
The shape of the Shimano D2 rims has been optimised with regard to both frontal winds and crosswinds. Extensive studies in the wind tunnel and on the road have shown that a wide rim profile with a deep rim well and flow angles of 0 to 15 degrees reduce drag the most. At the same time, this rim shape increases the lateral stiffness of the wheel and improves its vertical compliance, which provides more control, comfort and durability.

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.

Direct drive (Direct Engagement)
The Shimano Direct Engagement freehub is a ratchet freehub, which has the advantage of a much larger contact area compared to pawl systems. This leads to more drive rigidity. Thanks to its spiral shape, the outer and hub ratchet also engage firmly. This results in highly efficient and reliable energy transmission.

OPTBAL
Shimano OPTBAL is an asymmetric rear wheel lacing pattern that uses more spokes on the drive side than on the non-drive side. Symmetrical 1:1 lacing in combination with modern, wider-dimensioned cassettes can lead to uneven spoke tension, which puts excessive stress on the right-hand spokes. Spokes are more likely to break or nipples to come loose. OPTBAL counteracts this, balances the spoke tension and thus increases the stiffness, stability and durability of the wheel.

Habe die Laufräder im Austausch für meine DTSwiss ARC 1400 62mm gekauft. Ich muss sagen, es war eine gute Entscheidung. Die Laufräder machen am Rad richtig was her und laufen super geschmeidig. Seitenwindanfälligkeit ist subjektiv auch etwas weniger. Wirklich ein toller Aero Laufradsatz mit super guten Laufeigenschaften. Wirklich zu empfehlen.
