The high-profile wheel is the symbol of speed. The greater flywheel effect generates a propulsive force that helps push the entire bike forward. But it's not all that simple. There's also turbulence to consider. Testing guided by the laws of aerodynamics has allowed to analyse aerodynamic flow separation in race position. The result is the Kleos RD 62.

The Toray T1000/T700 carbon fibre rim features differentiated section profiles and a 23 mm inner well (front and rear wheel). Safety and ultimate reliability with all commercially available tubeless and clincher tyres.

The Ergal 7075 T6 hubs revive Miche RR-C (Racing Replica Ceramic) technology. Thanks to the partnership with CeramicSpeed, Miche has developed double-shield ceramic bearings taking into account every parameter: from lubrication to shields down to the thrust bearing/ball ratio for identifying the best possible solution in terms of smoothness and durability. The adjustment ring nuts present on both the front and rear hub make it possible to finely adjust the hub, when required.

The Aero Blade fairing placed on the left flange of the front wheel reduces turbulence and improves the aerodynamics.

The double-thickness stainless steel spokes with a crossed/radial 16+8 design feature different aero sections for the front and rear wheel. An innovation that, together with the Aero Blade, has been developed based on the data collected in the wind tunnel.

Kleos RD 62: designed and manufactured at the Miche factory of San Vendemiamo. Proudly Made in Italy.
