SECURE ATTACHMENT: Thanks to the QMR 2.0 system, each pannier can be easily adjusted and securely fixed to either side of the rear pannier rack. ECO-FRIENDLY: The cycle panniers are made from 100% PVC-free material and have been waterproofed without the use of harmful fluocarbons. WELDED WATERPROOF: The tarpaulin material of each cycling bag features welded waterproofing to keep all of your belongings completely dry and free from water-damage. POCKET STORAGE: Each of these waterproof panniers features an extra inside pocket so you can store your items separately and safely. CUSTOMISABLE CAPACITY: Each bag has dimensions of 33 cm x 30 cm x 17 cm and a capacity of 14L. However, the roll closure system means that you can customise the size of the bag and seal it so it remains water tight.
