    Description

    SHIMANO ULTEGRA 600 Bottom Bracket. BB-7400. NEW NOS
    Boring normal Ultegra 600 bottom bracket, NEW in box. Early 80s as they
    made so many versions of this BB, this looks early due to spindle. It is 113mm
    and has ground races but YST-3J markings. ENGLISH threads. All rubber
    seals are there. No BB plastic sleeve, it walked off. Just use tons of grease
    and the seals will do their job keeping out water/dirt. The smaller seals go on
    easier when assembling the BB. Larger seals press into cups one way and it
    is obvious. These things last forever if BB shell is prepped correctly and lots
    of grease. I use auto wheel bearing grease as this turns low rpm speeds.
    Weighs 12 oz. For normal 68mm BB shell width, 113 spindle. JIS taper for
    Japanese cranks, not for Campy style crank arms.
