Maximise Your Storage
Leverage your bike's triangular frame space to heighten storage capacity. Facile access from both sides coupled with internal and external pockets keeps your items orderly and in place even when the ride gets tough.

Eco-Friendly Materials
The external layer of the Adventure Triangle Bag features durable Ultragrid™ Ripstop material, sourced from recycled pre-consumer nylon waste, adding a level of eco-responsibility to your journey. It's not just about sustainability, though – the Adventure Triangle Bag is water-resistant, keeping your essentials safe and dry.

Seamless Mounting Option
Every Adventure Triangle Bag ships with a set of thumbscrews, empowering a seamless setup on compatible models. The straps included allow this versatile bag to be securely mounted on any bike frame, regardless of brand or model.

Optimise Hydration Storage
A long ride demands adequate hydration – and the Adventure Triangle Bag is ready to facilitate. The bag's design allows you to slot in your water bottles effortlessly, ensuring you have refreshments at an arm's distance at all times.

Size Guide for a Perfect Fit
To secure a snug and optimal fit, we provide a printout sizing guide. Confirm your bike is compatible, print the guide, and hold it up to your frame. Choose the smaller size if measurements fall between two options, for a seamless amalgamation with your bike. Whatever your riding habit is, the Adventure Triangle Bag by TREK is equipped to accommodate and organise your essentials, making your rides smoother and more enjoyable!
