HyperHubs FAQ Page

Here you find pre-calculated spoke lengths, spoke patterns and wheel building tips.

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.

Boost adapted version available

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.

The oversized front engagement freewheel offers a much wider teeth engagement surface upon which to spread the transmission torque.
Handles over a half-ton of chain pull.

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.

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.

Hhubs are not supplied with skewers/QR.
