    Good seals. Spins nice and quietly

    Bought this to replace the BB on my 2021 Specialized Rockhopper. This unit is by far better quality than the one that came on the bike. It has more seals to keep grime out. It spins so smoothly and unlike the one Iā€™m replacing is ultra quiet.

    Replacement Bottom Bracket

    The BB was the same type as the one originally in the bike, so it is a perfect replacement.
