Quick Pro ER:ONE Frameset Cassette The durable construction withstands IPX7The ER: ONE road frame represents a step forward in structural engineering. To achieve the combined goals of low weight, high stiffness, and reduced aerodynamic drag, every stage of development demanded precision. Each carbon ply is strategically oriented, resin ratios are optimized for strength to weight efficiency, and tube profiles are refined through repeated simulation and testing. From layup design to functional stress analysis, every parameter
