The Redshift mounting plate has a standard water bottle cage mount bolting pattern, so any standard water bottle cage can be attached to the mount plate. 

Any hydration system that attaches via a standard cage mounting pattern should be compatible. If you have a question about a specific system, send us an email at and we'll help you determine whether it is compatible.

Some hydration systems attach to the aerobar extensions themselves via clamps, velcro, zip-ties, or other means. 

While there is no problem using these types of hydration systems, please note that you typically won't be able to remove the aerobars while the hydration system is attached, since the aerobars need to slide away from one another in order to detach from the handlebar clamp.
