You can count on beefy and properly-dimensioned bearings coupled with a highly engineered axle, body and parts. Wheel rotates on 2 main bearings (6903-2rs) that can handle 250kg each in the worst static condition.
It took more than a year of continuous testing to develop and fine tune the HyperRear's fully-alloy front-engagement freewheel mechanism. This new device is able to manage extremely high torque values, offers 36 quick engagement positions for a precise feel and a minimal friction resistance.
Wear and tear of freewheel parts is also higher than conventional pawl systems, however the wearable parts can be easily replaced.
Micro-tuner: easy to set external bearing preload system integrates external Soft-Touch o-ring seals. Precise hub bearing setting ensures low bearing friction, durability and no play at the rim.
