The Topeak Fastfuel Tri-Platform Bag is an innovative platform mounted on the top tube (just behind the bike's handlebars) designed for storing gels, allowing the cyclist quick access to them and the ability to replenish calories without distractions during the ride. To prevent losing supplies during races, it can be secured with elastic cords. The Topeak Fastfuel Tri-Platform Bag is mainly made from durable polymer and easily attaches to the bicycle using nylon straps.
