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.

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.

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.

Internal pockets help keep your gear safely stored and ogranized, on even the bumpiest routes, while the external pockets keep your gear within reach at a moment's notice.

If for any reason you're not satisfied with a Bontrager or Trek aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.
