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.
Wheel rotates on 2 heavy duty bearings (6903-2rs) that can handle 250kg each in the worst static condition.
Now equipped with corrosion resistant stainless bearings.
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, offers 36 quick engagement positions for a precise feel and a minimal friction resistance.
Oversized front engagement freewheel offers a much wider teeth engagement surface upon which to spread the transmission torque.
It
is a true racing assembly
which is sensibly
stronger and lighter than conventional pawl systems.
As minor
trade-off its coasting sounds a bit more loud.
Wear and tear of freewheel parts is also higher than conventional pawl systems, however the wearable parts can be easily replaced.
You
can count on beefy and properly dimensioned bearings coupled with highly engineered
axle, body and parts.
And
it handles over a half-ton of chain pull.
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.
Here you will find pre-calculated spoke lengths, spoke patterns and wheel building tips.
