CNC Storm Drains
If your original Monocrome Bottom Bracket was purchased without CNC Storm Drains it is never too late to have us machine these drains into your bottom bracket. You can purchase this service along with your replacement bearings.
The CNC machined drainage channels allow any water to escape before it can enter the bearing. A necessity for those who ride in the wet or through rivers and streams. The CNC Storm Drains greatly increase bearing life and reduce maintenance requirements.
