This hydration system is the XLab Delta 200 with the carbon fiber gorilla bottle holder cage. It is custom designed to mount directly to the back of the BiSaddle Chrome-moly and Titanium base frames using our rear bracket (included). (Does not work with the previous full BiSaddle Carbon Base Frame. Will work with updated 2023 carbon frame.)
The BiSaddle X-Lab System is ideal for longer training rides or Century rides, where an extra bottle is necessary so you can have your favorite mix with you at all times.
