The Salsa EXP‑R Series Trillium Top Tube Bag keeps your most important ride items exactly where you want them: close at hand, easy to reach, and never in the way. Designed for gravel and mixed‑terrain riding, it opens one‑handed so you can grab snacks, your phone, or a battery bank without slowing down. The 1000D bluesign‑approved Cordura nylon body adds durability and weather resistance, while the streamlined shape fits cleanly into almost any front triangle.

With smart pocketing, molded‑tooth zippers, and a universal fit, Trillium is a simple upgrade that makes long days in the saddle smoother and more organized.

Why this bag works

Trillium solves the classic gravel problem of needing quick access without adding bulk or knee rub. The one‑handed zipper is perfect for mid‑ride fueling, the mesh pockets keep tiny items from disappearing into the main compartment, and the Cordura body stands up to heat, dust, and long‑term use. It’s a small bag that makes a big difference in ride flow.

• Gravel riders who want fast access to snacks, electronics, or tools
• Long days where organization and efficiency matter
• Bikes with limited frame‑bag space
• Riders who want a durable, low‑profile top tube bag that won’t interfere with pedaling
