Description of Enduro Bearings B543 2RS - ABEC 3 MAX - Headset Ball Bearing - 1-9/16x2x9/32"

Headset ABEC 3 MAX ball bearing with 1-9/16" inner diameter, 2" outer diameter, 9/32" thickness and two-sided rubbing rubber sealing. Spare bearing for Cannondale bearing type HD169.

Enduro Bearings don't mess around with inexpensive headset bearings, it's simply not worth it. While many headset makers will offer you Cr-Mo or standard steel headsets for your carbon road bike, steel cross bike, or full suspension mountain bike, they feel that's like putting bias ply tires on a rally car. Enduro Bearings don't offer the entry level for headset bearings. Instead they begin with chromium steel, Black Oxide finish A/C type and then offer full 440C stainless steel at the top. They are always engineered with the largest balls possible and dual lip seals riding in a micro groove for ultimate protection against sweat and the elements. They are filled 90% with high pressure water proof grease, so you don't have to ever guess if there is grease inside.

MAX bearings have 35-40% more load capacity than standard radial bearings. They accomplish 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 and headsets. Seals give maximum protection against the elements, while keeping the 90% fill of Almagard Extra High Pressure Grease inside.

ABEC 3 bearings use grade 10 Chromium Steel Balls and 52100 High Carbon Chromium Alloy Races.
The high precision balls are within 10/1.000.000″ round, twice as round as the industry standard, at it's highest level.
The alloy races are made from a 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-3 precision and noiseless movement. The riveted Steel Retainer stands for toughness, ABEC-3 tolerances and noise tested, C-3 or C-N Internal Clearance.
