While Ti springs certainly are light, they are poor performing. BetaC which is the most common spring wire used, requires the manufacture to over correct for the materials characteristics when winding. This makes the spring have a tremendously progressive spring characteristic with rates from spring to spring being all over the place.
Our HyperCoils are the latest available without compromise in either performance or durability. While there are lighter steel springs, the fine print will tell you that they need to be replaced each season or less depending on how much you ride.
