EXP-R Trillium Top Tube Bag

The EXP-R Trillium is designed with a streamlined, aerodynamic profile specifically to minimize knee contact. Its shape is optimized for gravel riding, ensuring it stays out of the way even when you are out of the saddle.

It mounts using TPU-coated webbing straps, which provide a secure, non-slip grip on your top tube. These adjustable straps are designed to keep the bag stable on rough terrain without damaging your bike's finish.

The bag features weather-resistant zippers and durable 1000D Cordura nylon, which will keep your gear protected during light rain or road spray. However, it is not fully submersible or waterproof, so you should keep sensitive electronics in a dry bag if you expect heavy downpours.

Yes, the bag is designed for one-hand operable zipper access. This allows you to grab nutrition or small tools quickly without needing to stop or take your eyes off the trail for long.

The four-way stretch mesh pockets are perfect for stashing items you need to access instantly, like empty gel wrappers, a multi-tool, or small trash. They keep these items separate from the main compartment so you don't have to dig around for them.

The bag features a universal front triangle fit, meaning it is compatible with most standard bicycle frames. Because it uses adjustable straps rather than a bolt-on system, it offers significant flexibility for different top tube shapes and sizes.
