The brand new Racing SpeedTM XLR with carbon rim for 80mm clinchers are been designed in our wind tunnel and developed with the precious indications of professional athletes. The result is extraordinary.
The aerodynamic design allows for top speed, acceleration and manoeuvrability even with cross winds; the smoothness levels exceed expectations: the CULT ball/bearing system is 9 times smoother than that of standard bearings!
But the Racing SpeedTM XLR does not need an introduction: a name which has been long associated with countless victories and today becomes the wheel of reference for triathlon or road races.
Behind this project is the exclusiveness of Cronitect® steel; using “Advanced by FAG” technology by Schaeffler Group employed for the bearing races. This is steel which takes resistance to corrosion to the highest level; to the point that, no grease is necessary for lubrication, just a small amount of oil.
The top quality ceramic balls, thanks to the absence of lubricating grease and the precision machining of the cup/cone, allow to drastically reduce the friction coefficient and thus increase the smoothness of the wheel by as much as 9 times compared to standard bearings. An outstanding result achieved by using cutting-edge technologies in the field of materials processing.
The test performed involves spinning the wheel to 500 rpms then letting it decelerate. The test results are amazing: the wheel equipped with CULT™ ball bearings continues its motion for a full 45 minutes, i.e. nine times longer than standard bearings.
