This cap closes the hole in the bottom bracket on a CAAD12 bike after performing an eTAP or Di2 conversion. These new models have slightly longer tabs, and are made from a tough, slightly textured, Nylon material.
We now offer versions in green, red, or textured black. These models have a smoother finish that is polished and painted by hand using tough enamel.
