Full Description

Design & Action

Tired of your tools rattling around loose or buried at the bottom of a pack when you need them most? The Frame Bag Large Bikepacking Bag is a waterproof frame bag built to lock 3.4 liters of gear inside your bike's triangle and keep it there through mud, rain, and rough terrain. This large frame bag for gravel bike and mountain bike setups uses three elastic rubber straps inspired by moto luggage plus three Velcro straps to clamp tight against your frame without rattling or shifting. The aerodynamic profile hugs most frame geometries, keeping weight low and centered where it belongs while you're hammering through singletrack or grinding out long distance rides.

Tech & Specs

Diamond Ripstop 420D TPU & Hypalon construction: Waterproof shell that laughs at rain and mud while taking a beating on rough trails.
3.4L capacity: Swallows tools, snacks, spare tubes, and layers without turning your frame into a cluttered mess.
Six-strap attachment system: Three elastic rubber straps plus three Velcro straps lock the bag to your frame for zero rattle and maximum security on rough terrain.
160g weight: Light enough to forget it's there until you need what's inside.
Aerodynamic profile: Fits most frame shapes without interfering with pedaling or water bottle access.

Fit & Kit

Mount the Frame Bag Large by wrapping the three elastic rubber straps around your top tube, down tube, and seat tube, then cinch the Velcro straps for extra security. Adjust strap tension to eliminate any movement and ensure the bag sits flush against your frame. The waterproof zipper keeps contents dry when the weather turns nasty, and the durable TPU coating wipes clean after muddy rides. This bikepacking frame bag works with most gravel bikes, mountain bikes, and touring setups, giving you organized storage for multi-day trips, endurance rides, or ultra cycling events without adding bulk to your back.
