Grade 10 Chromium Steel Balls:
52100 High Carbon Chromium Alloy Races:
Riveted Steel Retainer for toughness, ABEC-3 tolerances and noise tested, C-3 or C-N Internal Clearance
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.
Grade 5 Chromium Steel Balls:
52100 High Carbon Chromium Alloy Races:
Graphite/Nylon Ball Retainers
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.
Enduro Angular Contact (A/C) cartridge bearings are specifically designed for hubs, bottom brackets and headsets. In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction, and minimize wear. Wheel play can be adjusted out of the hub, to giving a more stable wheel, making it easier to adjust disc brakes, while still spinning freely

Because of the internal ball path design, all of the balls are engaged 100% of the time lending even maximum support through the entire pedal stroke. Filled with Rheolube special synthetic grease formulated in the USA, the balls are micro-coated with long lasting protection from friction. "LLB" dual lip groove seals and another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration. We back them up with a 1 year warranty.*
Enduro Ceramic Hybrid bearings have Grade 5 ceramic balls with ABEC 5 chromium steel races. Bearings are made from pure Silicon Nitride material with extreme high density from uniform compaction, the micro-structural development of this material during manufacturing is second to none.

The ZERØ ceramic bearings have ceramic balls and steel races. The balls are Grade 3, Silicon Nitride (Si3n4). These are the roundest balls you can buy without a military license. The races are treated with a black oxide coating, which helps prevent rusting in the bearing. The races are then reground to a mirror finish after this treatment. Finally, they are cryogenically treated for strength before assembly. We also use Silicone VV seals, which is the lightest drag seal available on the market.
Si3N4 balls with 52100 High carbon Chromium Alloy Races with Cryogenic Treatment: Cryogenic treatment takes the races down to minus three hundred degree Fahrenheit to normalize the crystalline structure of the material so the races will resist the hardness of the ceramic balls and get the maximum wear potential. "LLB" dual lip groove seals and another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration. We back them up with a 1 year warranty.*
Designed specifically for suspension pivots, Enduro Bearings pioneered MAX type bearings almost 20 years ago for bicycles to address the challenges associated with mountain bike pivots. These bearings have 35-40% more load capacity than standard radial bearings. Enduro accomplishes this with a special design where the maximum number of balls are inserted into the bearing. The race grooves are deeper on these bearings for more lateral support for the twisting and multiple forces associated with mountain bike pivots. LLU seals give maximum protection against the elements, while keeping the 90% fill of Almagard Extra High Pressure Grease inside.
