Included hardware provides seamless, bolt-on integration for both the Checkmate SLR and Checkpoint SL Gen 3 gravel bikes — giving riders secure storage mounting and a clean asethetic. Plus, finding the right bag size for your bike is easy with our compatibility guide.
04Made to maximize your hydration
The Trek Adventure Triangle Bag was designed to maximize the space you need to store your water bottles, so you can stay hydrated for the ride ahead.
05Designed with smaller frames in mind
Optimize your on-bike storage with a bag created with smaller frames in mind. The 1.0L triangle bag lets you store your ride essentials, without sacrificing the space needed for water bottles and other gear to keep your adventures going.
06Find the right size, right at home
With our printout sizing options guide, you can easily find the right bag size for your bike, hassle-free. Simply print the guide from a standard printer and place it on your bike's frame to find the best size for your ride. If the bag measures between two sizes, choose the smaller size for optimal integration.
