QR Code Link to This Post I thought I would use this pack on a recent bike tour but did not need it. It is a remarkable pack and I love the way it can clip into a pair of rear Back Rolller panniers so there is no need for bungees and it stays extremely secure. Bottom line, Ortlieb has created a really efficient pack system.Note that this pack is also used by many on their motorcycle. Here is a link to the product which tends to sell between $100-$115. https://ortliebusa.com/product/rack-pack/
