The Crupi Precise External Euro BB places the bearings outside of a Euro bottom bracket shell, allowing the use of much larger and more durable bearings. Precision sealed bearings, precision fit with no more plastic dust seals and Precision performance! A much upgraded bottom bracket that features machined tool slots so the tool will not scratch your BB, modified low friction alloy seals with less drag and is the lightest weight external bottom bracket offered today resulting in a Precision ride! Compatible with all 24mm race cranks designed to be used with external BB’s.
Available in Silver, Black, Red, Gold, Blue and White and also available with Tiramic bearings!
