Crupi Tiramic Outboard BB

Crupi Tiramic Outboard BB

The Crupi Tiramic Outboard BB 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

*  Arguably the lightest weight external bottom bracket offered today

*  Compatible with all 24mm race cranks designed to be used with external BB's.

*  Available with both standard sealed bearings or our Titanium coated ceramic bearings we call, Tiramic.

Weight = 3.24oz

The Crupi Precise External Euro BB works great on any 2-pc style crank with a 24mm spindle.  Features the TBT bearing made with Ceramic Balls and Titanium Nitrade coated  races for very low rolling resistance and long-lasting performance.  We call them Tiramic bearings!
