Description
The Shimano WH-R8170 wheelset has 60 mm high carbon rims and is the perfect complement for your Ultegra R8100 road bike groupset with Center Lock disc brake. Unlike Dura-Ace R9200 wheelsets, its steel pawl freehub is compatible not only with 12-speed but also with 11-speed cassettes. The model scores with top aerodynamics for high speeds, tubeless compatibility and stiffness. The rims have a jaw width of 21 mm for tires up to 32 mm wide and feature the wind tunnel-tested D2 design. They were each fitted with 24 double butted stainless steel spokes, with a specific lacing pattern used on the rear wheel to balance the spoke tension. At the center of the wheels rotate 12 mm thru-axle hubs with E-Thru technology for more torsion resistance. Cone bearings ensure durability and ease of maintenance.

- flat aerodynamic D2 profile, tested in the wind tunnel
- increased efficiency thanks to tubeless compatibility
- rear wheel with 2:1 lacing to compensate for tensions
- full compatibility with 12- and 11-speed cassettes
- hubs with internal grease coat
- polished bearings, CBN-finished, contact seals
- aluminum axles
- lacquered rims, anodized hub body
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 optimizes the stiffness-to-weight ratio and ensures easy handling via its reliable internal cam mechanism. It is characterized 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.
