    REI Members get back an estimated $ 3.00 on this item as part of their annual member refund.

    The REI Member Dividend

    The REI dividend is a unique benefit of membership in the REI co-op. It's comprised of your member refund—typically 10% back on eligible purchases—and/or your REI Visa® card rebates.

    Each March, active REI members and REI Visa cardholders who earned a rebate receive a refund in the form of an annual dividend notice.

    Only active members receive annual dividend notices. To maintain your active status as an REI member, you need to make net merchandise or shipping purchases of at least $10 per year, unless you joined that year. Member numbers are issued in one name and only that person receives the member refund. Your number can be used by others in your family, but it cannot be transferred to someone else.

    Shimano UN55 Square Taper Bottom Bracket - 68mm is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Solid UN53 replacement My son's touring bike (Surley Long Haul Trucker) was in a bike-car accident where the frame and back wheel were bent. The old bottom bracket, a UN53, had a cracked sleeve nut because it was made of plastic, otherwise it was fine. This new one has a reasonable cost, fits exactly the same as the UN53, and the sleeve nut is aluminum instead of plastic. It is working fine and should last a long time.
