Redline researched and considered many different materials for Project 79. After much deliberation it was decided that carbon fiber would be the ultimate choice for this frame. Carbon Fiber gave engineers and designers the ultimate flexibility in design and a great strength to weight ratio. Redlines Carbon fiber manufacturing process also allows us to add or subtract the amount or type of fibers in certain areas of the frame. This allowed Redline to fine tune the weight, stiffness and the ride quality of this frame. With test data from labs and real life feedback from the top riders in the world Redline
