Lightweight two-part handlebar bag for true globetrotters, made from a lightweight, waterproof pack sack with roll closure and compression valve on both sides. The handlebar bag is made of durable material with an elastic compression cord and material loops on the top, allowing for quick loading and unloading during spontaneous stops. The bag holders can remain on the bike while the pack sack can be taken along. The sturdy straps can be adjusted to fit a variety of tube diameters thanks to the Velcro, preventing twisting, and the included spacers are also suitable for carbon bikes.
