Crupi Precise Tiramic External Euro Bottom Bracket (Black) (24mm)

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!

• Machined tool slots so the tool will not scratch your bottom bracket
• Modified low friction alloy seals with less drag
• Arguably the lightest weight external bottom bracket offered today
• Compatible with 24mm race cranks designed to be used with external bottom brackets
