    StarStarStarStarStar Excellent Upgrade

    Product: Enduro Ceramic BB90/BB95 Kit for Shimano Cranks
    Ownership: two weeks
    Tech Knowledge: average


    Purchased these bearings to replace the stock bearings that wore out in my Trek Madone. Easy to install (thanks to press fit bottom-bracket design), whisper quiet and smooth. Very happy to have made the upgrade - especially at such a low price point.


    Should have switched to Hess bearings sooner.

    Great product, fit well, right price

    StarStarStarStarStar Did not work for me

    Ownership: several months

    Less than 500 race miles and need to be replaced. One is very grainy. Both slide in and out too easily.

    Other Thoughts

    One of the bearings is grainy after less than 500 miles. They slip in and out so easily that they appear to be undersized. The bottom bracket clicks and creaks and has to be repacked with grease every 100 miles or so. Was not a good purchase.

    The bottom bracket shell width is the width, in millimeters, of the frame where the bottom bracket is mounted.

    Bottom brackets must fit the frames interface type. For example, an english threaded bottom bracket can only be installed on a frame that accepts english threading.

    The spindle interface type must match with the crank arms.
