Kleos Rd 62Mm Tubeless Wheels

This 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 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. **The Aero System** The careful study of the rim's aero profile together with the clever differentiated thickness lamination of the high- and medium-module fibre mix make for a balanced wheel with absolutely superb stiffness and responsiveness. This design has made it possible to lighten the rim thus reducing rotational inertia, achieving a weight of 1560g. The mixed profile combination of the 50 mm front wheel with 21 mm inner well and 62 mm rear wheel with 23 mm inner well produces a wheelset that couples a reduced weight of just 1500g with the most advanced concepts of aerodynamics. **Spirit Becomes Style** The elegance of the racing grey paint meets a new graphic identity. After being applied, the water transfer decals undergo heat treatment. This eliminates the step effect, increases resistance and makes it possible to transfer the lettering and colours to the rim. **Ultimate compatibility** Three freewheel bodies available: Shimano HG, Campagnolo (Classic and N3W) and SRAM XDR. Made from Ergal 7075 T6, they feature a three-nipple pawl carrier in titanium. **These wheels are covered by a Crash Replacement Scheme offered by Chicken Cyclekit.
