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.
Wheel owners (especially 29ers) will appreciate the extreme spoke camber. The drive spokes lace closer to right dropout than on any other hub on the market. This translates into healthier and more rigid wheels.
Straight pull spokes increase wheel stiffness under sprinting. They appreciably reduce lateral flex and increase torque transmission reactivity. All this with a slight weight reduction too!
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, and offers 36 quick engagement positions for a precise feel and a minimal friction resistance.
The oversized front engagement freewheel offers a much wider teeth engagement surface upon which to spread the transmission torque, and handles over a half-ton of chain pull.
It is a racing assembly sensibly which is appreciably stronger and lighter than our conventional pawl systems, with the minor trade-off that coasting is a bit noisier.
Wear and tear of freewheel parts is also lower than conventional pawl systems, however 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 and no play at the
rim.
FEA:
every single cubic mm receives hours of Finite Element Analysis. HyperRear
axles, body and mechanism have been designed to handle the abuses of X-C and
marathon racing and more.
Here you will find pre-calculated spoke lengths, spoke patterns and wheel building tips.
