Compact Triangle Frame Bag

The ROCKBROS triangle bag weighs 0.35 lb and provides 1.2L of storage beneath the top tube. It is built for road, mountain and commuter cyclists who want tools, phone and nutrition within reach without a bulky pack.

Check Frame Clearance Before Buying

Verify that your top tube and down tube leave enough open triangle space for a bag of this volume. The three strap mounts must wrap cleanly around the tubes without interfering with cables, bottle cages or a front derailleur.

Three Strap Mounts and Layered Shell

Three sewn-on straps lock the bag in place on rough terrain. The shell combines a PU-polyester outer, 5 mm foam middle and polyester inner liner to protect contents from vibration and road spray.

Questions about this item

What comes inside the ROCKBROS Bike Frame Bag package and what extra items must I buy separately?

The package contains the triangle frame bag with three pre-sewn mounting straps; no tools, phone mounts or additional hardware are included and none are required for installation.

How do I decide which capacity version of this bag to choose?

This model is offered in a single 1.2L size, so there is no capacity choice to make; select it if the stated volume matches the gear you need to carry.

What does the 1.2L capacity mean once the bag is mounted on my bike frame?

It provides a single main compartment plus a mesh pocket large enough for a phone, keys, nutrition and small tools while fitting neatly under most road, mountain or commuter bike triangles.
