The Entity SB15 Saddle Bag is big enough to carry essential tools, your mobile phone and a spare tube under your saddle. The 0.3-litre saddle bag is made of a tough and water-resistant fabric that keeps your contents clean and dry. Outside, a reflective band improves visibility on the road and allows you to clip a rear light to it. The SB15 clamps onto the saddle via 3 independent, tool free, hook and loop straps that are designed to stop the saddle bag from swaying when you go on a hard sprint. Weighs only 50 grams 0.3 Litres capacity Tool free installation Reflective strip and logo Rear light mount strap Tough, water resistant construction Slim design won’t rub on your legs when you pedal
