Only the best bearings go into our hubs. We use bearings by Enduro which are world class bearings specifically made for bicycle use. They use 52100 High Carbon Chromium Alloy Races with heat treating followed by cryogenic treatment. The balls are Grade 3. That means that the ball is 3/1,000,000” tolerance of sphericity. And because bicycle bearings turn at a relatively slow speed, they are then filled with more grease then normal which helps provide all rolling surfaces with a fresh supply of an extra high pressure grease, Mobil XHP 222, which is an excellent and clean rolling grease. All our bearings are sealed on both sides with light contact rubber seals.
15mm bearings: High Flange Front, High Flange Rear, Fhub,1998-2015 Disk-FHUB, 1998-2015 Disc-WORD, WORD, and Fixed-Disc-Word
17mm bearings: Disc-WORD and Boost Disc-WORD
20mm bearings: Disc-FHUB, Boost Disc-FHUB, and pre-summer 2015 Thru-Axle Disc-FHUB
Confused as to which bearing fits your hub by description? Measure the outer diameter of the old bearing, or the inner bearing bore of the hubshell itself.
From Enduro: “Bearings should never be installed by pressing on the inner race. Always press on the outer race with a pilot brushing or similar tool, which will only make contact with the metal side of the outer race. A bearing press or similar should be used to exert the force needed to press the bearing into the housing. Care needs to be taken that the bearing is started straight and not at an angle to the housing.”
