Good quality bottom bracket that helps provide the optimal chainline for the Wabi crankset. Shimano's core square tape bottom bracket provides good all-around value and quality. Features a hollow spindle. Fixing bolts not included. In general, we recommend the 107mm as a replacement for current Wabis. 110mm is recommended if you are going to 50T chainrings or larger or you are looking for a standalone option for the Wabi crankset for other frames.
