The Co-Pilot bag is a universal stem bag designed to fill a need and space! Use this bag on your bars, carabiner, belt, or saddle. What makes this bag special is our specific three-point mounting system, which creates minimal sway and sag.

This bag can be mounted on either the right or left side of the bars/stem. With its one-handed closure system, tug up on the cord end to close the collar and secure your items inside. Need a size up? Check out our Auto Pilot Stem Bag.

Rosa Sewing at the Road Runner Bags Workshop
Rosa has been with our team since 2019 and is one of the seamstresses responsible for assembling your bag. Each bag is crafted using the finest materials made in the USA.


1. Mount the stem strap, which runs vertically and is permanently attached to the bag.

2. Attach the handlebar strap, which runs vertically and is removable for attachment on either side of the stem. 

3. Strap the headtube strap which runs horizontally. This creates a third mounting point and gives the bag zero sway or sag.

Love these little bags

I'm a big fan of the co-pilots! They're a great place to stash a bottle when running a full frame bag or an excellent place to put snacks and quick access goodies at other times.

5 Years and still awesome!

My Co-Pilot has been awesome, have used it many days for commuting and bike packing. 5 years old a little washing occasionally and it still is in great condition. I have used for keys, snacks, and or any small gear I need to stash like gloves. Great stem bag you won't regret buying!

Great little bag!

This Road Runner bag is one of the most adaptable pieces in my collection. It can carry everything from my phone and camera to snacks. Truly, it's a bag that does it all!
