Co-Pilot Stem Bag

Sold Out

Whether you need another water bottle position for longer rides or quick accessibility to hydration, the Roadrunner Co-Pilot Stem Bag is what you're looking for.

Co-Pilot mounts on either side of your stem and features a very nifty, truly one-hand operated drawcord that opens and closes the bag to keep your bottle in place over rough terrain.

The bag includes three high-quality velcro strips that eliminate sway and sag and can be mounted universally on any bike.

Designed and manufactured in the USA by Road Runner Bags of Los Angeles.

Nice!

Works great for a water bottle, snacks, a small camera! Easy close and open.

Simple and awesome!

Great way to add beverage carrying capacity to your fully frame bagged rig! A plus for easy one-handed operation and plenty of places to dangle your other belongings if you desire. Love it!

Should have known

I have seen this type of bag on so many bike nerd bikes, I figured there must be something to it. Turns out, the nerds are right, this bag is super convenient. I like the three well-placed straps. Did a long day of fire roads and blue MTB trails on my gravel bike and the bag stayed put. Even found myself rotating water bottles so I always had a full one in the bag. Going to try two bags up front next.
