Enduro Bearing Comparison
Be sure you are comparing “apples to apples” when you evaluate and choose your bearings. One of the most important features of a bearing relating to smoothness and longevity is the ball size and the quantity of them. Below are 3 scale drawings of our Enduro Bottom Bracket bearing, a competitors’ standard Bottom Bracket bearing and a really sub-standard design of Bottom Bracket Bearing we purchased from another website. While the static capacity of our bearing is 726 lbs. and the sub-standard bearing is only 229 lbs., if this is not enough to convince you of ours, consider the fact that the larger balls of the Enduro bearing will roll easier and with less energy loss than the smaller balls in the other bearings. The Enduro balls will spin about 1/2 as many times for 1 crank rotation, and, because of the deeper ball groove they sit in, will stay in alignment of the ball path and with less friction during the high torque forces exherted by a typical crankset. A deeper ball groove also lends to the lateral strength of a bearing. The groove or ball paths in our bearings are the deepest possible, cupping the bearing to the maximum height and support; see the Side Profile Illustrations:

Grease:
At Enduro we utilize several types of grease depending on the projected application of the bearing.

For Enduro Ceramic Hybrid Bearings, we use Kyodo Yushi PS-2 for its protective interface between ceramic balls and metal races and for it's high speed properties and minimum rolling resistance. Speed and Protection for high precision bearing systems.

For Enduro MAX type bearings, we use CRC Sta-Plex Marine Grease. This grease will not wash out or break down under any extreme conditions including power washing, salt water intrusion from the salted roads, or even dirt getting into the rolling areas. The High Pressure properties of this grease provides a cushion for the sharp blows that suspension pivots will endure. Tough and Tenacious for high impact and extreme conditions.

For Enduro ABEC 3 level precision Enduro Bearings we use Mobile HP 222 which is another high pressure grease for maximum protection and constant lubrication. This synthetic grease holds up under all conditions and will not break down. We also use the Kyodo Yushi PS-2 as mentioned above depending on the application, such as the ABEC 5 level precision bearings.
