Our front hubs have been engineered to provide maximum lateral strength and stiffness of the built wheel, and to minimize bearing drag. This allows for the wheels to be built with fewer spokes, further reducing overall drag.

The front hub flanges are placed as close to the dropouts as possible while still allowing for a conventional cross pattern build. This creates an extremely wide "base" for the wheel. In addition, the bearings are placed as close to the dropouts as possible (3 mm), which increases the stiffness of the built wheel, effectively eliminating axle flex and reducing loaded bearing drag. Most conventional hub designs position the bearing 10-15 mm away from the dropout, creating a span of axle between the bearing and dropout. Under load, this span acts as a lever and causes the axle to flex. This produces two adverse effects. First, it allows for more lateral movement of the rim due to side loads. Second, it increases loaded bearing drag as the axle flex forces the inner race of the bearing to become misaligned with the outer race.

Front hubs feature our threaded axle assembly which makes it easy to service the hub. Proper bearing adjustment is achieved with a "spacer lock" system. Each hub is adjusted at our factory so that the adjusting cap tightens against the axle. This makes it impossible to over tighten the bearings, which is the primary cause of bearing drag, wear and premature failure. This also allows the end cap to become a rigid extension of the axle, which improves overall axle stiffness.

Enduro Bearings

Our hubs ship standard with Enduro ABEC-5 bearings.


High precision balls are within 5/1,000,000″ round, twice as round as the industry standard, at its highest level. Vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-5 precision and noiseless movement. Nylon with graphite retainers are virtually friction-less while providing constant lubrication.

The bearing seals are dual lip, groove type seals rather than standard 2RS types that other manufacturers use; one lip to keep the dirt out and the other to keep the 90% grease fill inside. Bearings are filled both sides with Mobilgrease XHP 222 mineral oil based grease for the best protection and long lasting set up. Another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.
