The Topeak TriBag Frame Bike Bag (Medium) is designed for cyclists who demand quick, efficient access to their ride essentials without sacrificing aerodynamics or comfort. Perfectly mounted on the top tube near the stem, it allows riders to grab nutrition, tools, or electronics on the go—ideal for triathlons, endurance rides, and daily commutes. The bag features a padded main compartment to protect delicate items and two mesh side pockets for additional organization. Built from rugged 600 denier polyester with a waterproof 70D ripstop nylon inner lining, it stands up to rain, dirt, and sweat. The nylon strap mounting system ensures a secure, wobble-free fit on most frame geometries, while reflective detailing adds low-light visibility. Compact yet surprisingly spacious, the TriBag is the perfect balance between accessibility, protection, and sleek design for performance-focused riders.
