Handlebars are for your hands! Our machined aluminum Handlebar Stub allows you to carry most bar-mounted accessories directly on The Handlebar Bag. Each bag accepts two Handlebar Stubs via the M5 threads on each side of the bag. Install notes Recommended torque: 6-8Nm, using a square-end, 3mm hex key. Align wings on the Handlebar Stub with the slots on the Accessory Rails.
