Designed for lightweight off-road bikes, the GRT718 panniers have a 15 litre per side capacity and don’t require any mounting brackets – simply throw them over the rear of your seat and secure them with the straps provided. Made from light-weight and durable 840D Nylon, with a TPU coating, these bags are tough enough to take off-road abuse, while the roll-top closure system ensures waterproofness to IPX5. External straps make it easy to attach other items, like the GRT717 tool bag, and the hi-viz interior makes it easy to find your things in low-light situations.
