A new and specifically designed polyurethane lip seal enhances the protection of freewheel mechanism.
The new "twin-Life" hub-shell features a second additional row of splines for the floating ring.
The second fitting position allows to rebuild the hub back to brand new conditions in case it get badly worn out by a neglected maintenance.
29"(and 27.5") wheel owners will surely appreciate the benefits of extreme spoke camber.
Drive spokes lace closer to right dropout than on any other hub on the market, see the sketch:
HyperCamber system offers a 10% gain of spoke angle (compared to the already optimized HyperRear).
This translates into healthier and stiffer wheels.
Straight pull spokes increase wheel reactivity under sprinting.
They appreciably reduce lateral flex and increase torque transmission reactivity. All this with a slight weight reduction too!
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.
Sturdy, precise and incredibly light: no shortcuts taken in our quest to reduce weight.
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.
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.
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 minimum frictional resistance.
Oversized front engagement freewheel offers a much wider teeth engagement surface upon which to spread the transmission torque.
And it handles over a half-ton of chain pull.
It is a true racing assembly sensibly 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 higher than conventional pawl systems, however the wearable parts can be easily replaced.
