OPTIMIZED SPINDLE: MORE POWER TRANSFER AND RELIABILITY
The spindle of the new CARBON BLADE has been completely redesigned. It is built around an oversized axle and spindle that pass through internal roller and needle bearings located directly under the pedal platform. This new construction allows a gain of approximately 2 to watts at 100 rpm.
The distance between the roller and needle bearings has been increased by 25%. This provides more rigidity along the entire length of the spindle, and as a consequence, improved power transmission.
Special attention has also been given to ensure that it is water resistant. Weather resistance has been improved by 120% for even more reliability and longevity. To accomplish this, the new spindle received an updated endplug with an o-ring washer and has also been equipped with an internal, double-lipped seal.
LOOK axles are only approved after a rotational test of 2 million cycles at 100 rpm with a load of 90 kg on the center of the pedal and an eccentric rotation (which creates stress on each revolution). This is equivalent to a sprint by André GREIPEL of 1700 watts at 100 rpm for 333 hours! This test is much more demanding than the current standard, the EN14781.
