Our new shipment of chain stays are ready for delivery. With this order from Reynolds, we have tweaked the design to give builders even more design flexibility than ever before. Not only does the new stay offer builders a much wider range of stiffness adjustability than any other chain stays on the market, but it is considerably lighter than all but the most flexible stays available. Working with Reynolds, we were able to start the swaging process with a thinner taper gauge then other mills use, giving us a final small end gauge which meets the specification of a single taper gauge. In most other cases, builders are stuck with extra thickness and weight where they don't want it and less stiffness where they need it most. We considered ordering the stays in 531 material because of its excellent notch hardness properties, but the weldability of the material would have suffered.
