Description

Front hub HyperFront 74g

Material: special 7075TXX
Standard: Front 9x100mm or QR15
Available Drillings: 24, 28, 32H
Sealing: external Soft-Touch OR, 2+2 RS
Micro-Tuner: easy to set external bearing preload system
Axle construction: multishaped 17mm rectifyed to micro tolerances
Bearings: 2x17-26 2RS sealed ABEC-5 stainless cartdriges (option 17-30)
Finishing: "hart-coat" sides, black anodized body
Graphics: laser etched.
Weight: 74g

Sturdy, precise and incredibly light
Now equipped with corrosion resistant stainless bearings
Micro-tuner: easy to set external bearing preload system integrates external Soft-Touch Or seals.
Precise hub bearing setting ensures low bearing friction and no-play at the rim.
Hi-tech rarely combines with maintenance easiness, not here!
Straight pull spokes increase wheel stiffness under sprinting. They sensibly reduce lateral flex and increase disc braking torque transmission. All this with a slight weight reduction too.
FEA: every single cubic millimeter of material receives hours of Finite Element Analysis. HyperFront axles, body and mechanism have been designed to handle the abuses of X-C and marathon racing and more.

Optional: HDC-Hybrid F hybrid-ceramic bearings.
Optional: 17-30 2RS bearing on disc side for heavy duty use.

HyperRear2 QR12-XD (standard 142, 142+, X-12) Sram XX1 XD-Drive compatible.

Optional: "HDC-Hybrid R" hybrid-ceramic bearings.

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. And it 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.
You can count on beefy and properly-dimensioned bearings coupled with a highly engineered axle, body and parts.
FEA: every single cubic millimeter of material 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.
