Weighing just 74 grams, the Extralite HyperBoost3 F hub is the lightest Boost front hub in the world!. It's a straight pull hub with flanges for 24 or 28 spokes and is made entirely of 7075Txx aluminum with refined CNC machining, equipped with a 17 mm diameter axle optimized with variable thickness. Comes with two 6803 2RS stainless steel bearings but as an option is possible to get ceramic or ceramic hybrid bearings and the oversized disc side bearing (6903 2RS). There's an external regulator ring for adjusting the axial bearing pre-load and side play. Disc brake rotor attach is 6 holes International Standard. The hub is compatible with Boost forks (110 x 15 mm). Black anodized finish with laser graphics. The HyperBoost3 F is 100% Made in Italy.
The Extralite HyperBoost3 F is a light and refined front hub for MTB use (XC, Marathon, All Mountain, Trail, Enduro) equipped with the Boost standard, therefore compatible only with forks equipped with a 110 mm width and 15 mm diameter thru axle. The brake disc rotor attachment is the classic 6-hole International Standard.
It is a hub equipped with Straight-Pull flanges for straight pull spokes which guarantee greater wheel stiffness, less lateral flexibility and greater reactivity in transmitting the drive torque. It is possible to choose between 24-spoke or 28-spoke flanges. The sizing of the hub body is such as to ensure the best possible balance of the spoke tension on both sides of the wheel and allows the use of spokes of the same length on both sides of the wheel and on both wheels.
The hub body is entirely machined from solid through sophisticated CNC numerical control machining from a special 7075Txx aluminum bar, shapes and thicknesses are optimized to provide the best compromise between strength and weight with a truly captivating look. With the same material and philosophy are also made the axle which has an oversize diameter of 17 mm and variable thickness and the external end caps. The hub body has a black anodized finish with white laser graphics, while the axle end caps have an hard anodized finish to ensure greater durability and resistance by being in direct contact with the fork.
The HyperBoost3 F hub rotates on a pair of sealed bearings 6803 (17x26x5 mm) with 2RS double protection, on request it is possible to have the oversized disc side bearing 6903 (17x30x7 mm) with a total weight increase of about 8 grams. The bearings fitted as standard are excellent ABI 440c stainless steel with great resistance to corrosion and consequently suitable for MTB use, especially in severe conditions with water and mud. As an option, it is also possible to mount Hyper Ceramic bearings or the Enduro XD-15 ceramic bearings. The table below summarizes the advantages and disadvantages of the different solutions:
Whatever the type of bearing chosen, Extralite pays great attention to the coupling between bearing, hub body and axle, selecting the components based on tolerances in order to guarantee the best smoothness and durability. There is also an external adjustment system of the axial play and pre-load of the bearings which allows to maintain the best smoothness and to extend the life of the bearings as they wear. The HyperBoost3 F hub is also equipped with a protection system against dirt and external agents thanks to the o-rings that further protect the bearings despite the fact that they are already equipped with double sliding protection. These precautions allow an excellent life of the bearings despite the reduced size and weight.
With a weight of only 74 grams (with 6803 bearings), the HyperBoost3 F is the lightest MTB Boost hub in the world, it allows a considerable weight saving, but it does so without compromising reliability and performance, thanks to the precautions adopted and the great build quality and materials used. The series of Extralite HyperBoost hubs has been present on the market for years and with its continuous evolutions it maintains what is a primacy not only on the scale but also in technology. These are the hubs we use to assemble our lightest custom wheels (you will also find rear hub and Lefty front hub on our webshop) so do not hesitate to ask us for further information or quotes, even for complete wheels solutions that you cannot currently find on our website.
