Description
EXTRALITE hub set HyperBoost3 silver | Enduro Bearings stainless steel bearings SRAM XD 36 teeth BOOST
Stable, precise and incredibly light. With the HyperBoost3 hubs, the Italian lightweight specialists are raising the bar even higher.
With a weight of 222 grams, the HyperBoost3 hub set is one of the lightest pairs of hubs that money can currently buy. Elaborate computer simulations, countless prototypes and a long test phase under the toughest conditions guarantee you a long service life.
Despite their low weight, hubs are approved for enduro use if you drive well. The freewheel mechanism has also been optimized. The toothed disc in the hub body has lost 20% of its weight and sits in a newly developed tooth system. In addition to improved engagement speed when accelerating, this also reduces resistance when rolling. The service life and wear have also been optimized by these changes compared to the predecessor. Those who prefer a harder pace can install larger 6903 2RS bearings on the disc sides of the front and rear wheel hubs. The weight then increases by 8 grams per hub, but the hubs are significantly more durable and able to withstand higher loads.
As usual from Extralite, the hubs are perfectly finished. Minimal tolerances and high-quality materials leave no doubt as to the quality and stability of these works of art. The silver hub shells rotate on 6803 2RS deep groove ball bearings around the multiple butted axle . O-rings on each side provide additional protection against water and dirt. For a long service life of your bearings, you can use Micro-Turner to perfectly adjust the bearing play at any time.
In addition to the organic oversized shape, the modern concept of the hubs also includes the spoke flanges, which are intended for straightpull spokes. The straight spokes result in a straighter power flow and the elimination of the curved spoke head means there is one less potential weak point in the wheel.
36 teeth freewheel mechanism
The spur gear has 36 teeth. This results in a maximum idle travel of 10° when accelerating.
stainless steel bearings
Best corrosion resistance and the optimal choice if the wheel is often used in adverse conditions.
