Profile Design RML System

The RML System is designed to mount directly to standard saddle rails. It is compatible with most traditional rail designs, but it may not fit on some proprietary or integrated saddle rail systems found on certain aero road bikes.

Yes, the system is flexible and can be configured to hold either one or two bottles depending on your hydration needs for the ride.

Because the RML System occupies the space directly behind the saddle, it may limit the use of traditional strap-on saddle bags. However, the system includes integrated straps specifically designed to secure a flat repair kit or other small essentials in that same area.

The system is designed to work with standard bicycle water bottles. For the most secure fit, especially on rougher roads, we recommend using bottles with a pronounced groove for the cage to grip.

By tucking the bottles behind the saddle, the RML System minimizes the frontal surface area compared to frame-mounted cages. This placement is generally more aerodynamic, as it hides the bottles in the rider's draft.
