The largest bike bags in the world are also available in wear-resistant, waterproof material made of polyester. The remaining features are identical to those of the Back-Roller Pro Plus: additional front pocket, proven roll closure, and ingenious QL2.1 system for a super convenient and secure attachment to virtually all commercially available bike racks. Those who hesitate owing to a lack of stowage space to venture off on a bike tour around the world, a European bike vacation or a multi-day tour with the family will definitely no longer have any excuses! Time to pack up and take to the road!
