The BiKASE Long John takes top tube bags to the next level. Need more space than the Trifly but really don't want a full-fledged frame bag? Then the Long John is the perfect option for you. With multiple mountain straps and positions, the Long John can be mounted like a traditional top tube bag, or... flip it over and use it like a frame bag. With side zippers, it doesn't matter how you mount it... your gear always remains in reach! - Can be mounted above or below the top tube - Side zippers allow the rider to access their gear at any angle - Multi-position straps with elastic to mount firmly on top tube - Works with bikes with limited space between top and down tubes
