HyperGravel HC From 995g

Hard-Core Gravel-specific tools

Impact tested as for MTB standards Toray T800 layering with individual reinforcements at each nipple fitting

Wide rims with beefy side walls

HyperSmart3+ F offers the same axle stiffnes both if TA12 or QR15 featuring on both versions a Ø17mm axle and beef 6803-2RS bearings Equipped with 17-26mm corrosion resistant stainless bearings on an oversized axle that is multi-shaped and individually lapped to micro tolerances

HyperSmart3-R offers the max spoke camber for MTB lacing and self-adapts when equipped with road-gravel freewheels

Micro-tuner ensures a very precise bearing setting: minimum bearing friction with highest bearing durability and no play at the rim Additional external Soft-Touch O-ring seals keep dust and moisture away from the 2RS bearing seals promoting bearing longevity

Super adaptive, yet incredibly light and precise Fully convertible in all standards

Wide and beefy disc flange reduces spoke stress under braking Lightweight rims reduce angular moment enhancing acceleration and minimizing the unwanted gyroscopic effect

Equipped with superb Berd spokes or HyperLite, the highest possible quality choices

Berd spokes are made from an advanced polymer called ultra-high molecular weight polymer that has 12 times the strength-to-weight ratio of steel (floats on water)

Really stiff, strong and light

Bearing Options

All Extralite hubs and wheels are offered with a choice of ready installed bearings among the best available today.

All bearings feature low-friction rubber seals on both sides.

Hyper hubs, that are specifically designed for off-road use, feature an additional external O-r seal that protects the bearing seals.
Internal bearing selection
Each bearing unit is individually selected by Extralite staff, we check seal drag, rolling smoothness then select and divide them 3 different fitting classes of internal diameter, each class is 2 microns by the next one.
Despite all our bearings come directly from very high quality manufacturers our staff individually checks each unit for rolling smoothness and bore dimensional tolerance.
Extralite staff checks rolling smoothness and seal drag resistance first, then all the units passed are selected and divided in 3 different fitting classes of internal bore, each class is 2 microns by the next one. All that allows our famous truly perfect axle to bearing fitting that together with our precise bearing preload offers very high mileage with minimal rolling resitance.

Read well these basic info before ordering the parts.
Bearing replacement is not an easy operation as it may seem.
Additionally the installation of any kind of Ceramic bearings requires a very good specific expertise.
Extralite offers complete tool-sets for hub maintenance: the Pro-tool kit 1 and Bearing-sitter includes bearing inserting tools in every bearing sizes used on UltraHubs / HyperHubs / CyberHubs.
If your hub was originally equipped with standard bearings it will probably require micro-tolerance adjustments to axle and bearing fittings, this
to allow proper bearing rotation and durability (these operations are for real experts only). Alternatively send your hub to us for this servicing.

Read well Bearing Tips before attempting a bearing replacement.
