Revelate Designs Tangle Frame Bag The Tangle from Revelate is the go to weather-resistant frame bag for travelling cyclists, turning unused space within the bike frame into efficient and easy to access storage. This frame bag is super useful for carrying tools, spares, food and tent/tarp poles. The Revelate Tangle bag is handily split in half and coloured white/yellow internally for improved visibility. The right-hand side offers a large space running the entire length so is handy for long / larger items?Çö like pumps (the bag now includes clips to hang a pump) whilst the left-hand side is smaller and has an inner compartment for managing smaller items. Many kilometres of riding on and off-road have gone into finding the best solution to fixing these bags securely and ironing out the features. Once the frame bag is strapped within the frame using the easy to fit/adjust reinforced velcro top tube straps and coated cam-lock attachments, the bag is super stable; barely noticeable on the bike. Inner Frame measurements are essential prior to purchase. Measure the inside length of your top tube to check the length, as well as the inside height of the head tube to check the depth.
