EXTRALITE rear hub HyperBoost3 R | Enduro Bearings Stainless steel bearings SRAM XD 36 teeth 12x148 mm BOOST
Stable, precise and incredibly light. With the HyperBoost3 R rear hub, the Italian lightweight construction specialists have raised the bar even higher.
Weighing in at 148 grams, the HyperBoost3 R is one of the lightest hubs money can currently buy. Elaborate computer simulations, countless prototypes and a long test phase under the toughest conditions guarantee a long service life.
In the current version, the Italians have once again tightened the weight screw and defined the new benchmark for hubs with 148g. Despite its low weight, the hub is approved for enduro use with a good riding style. The freehub mechanism has also been optimized. The toothed pulley in the hub body has lost 20% in weight and sits in a newly developed toothing. In addition to an improved engagement speed when starting off, 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 gear can install a larger 6903 2RS bearing on the disc side. This increases the weight of the hub by 8 grams, but makes the hub significantly more durable and more resilient.
As you would expect from Extralite, the hub is perfectly finished. Minimal tolerances and high-quality materials leave no doubt as to the quality and stability of this work of art. The black hard-anodized hub body rotates on two 6803 2RS deep groove ball bearings around the multi-butted axle. An O-ring on each side provides additional protection against water and dirt, and you can adjust the bearing play perfectly at any time using the micro-turner to ensure a long service life for your bearings.
In addition to the organic oversized design, the modern concept of the hub also includes the spoke flanges, which are designed for straight-pull spokes. The straight spokes ensure a straighter power flow and the elimination of the bent spoke head means one less potential weak point in the wheel.
36 teeth
The spur gear toothing has 36 teeth. This results in a maximum free travel of 10° when starting off.
Stainless steel bearings
Best corrosion resistance and the optimal choice if the wheel is often used in adverse conditions.
