SDG Formula FXR Saddle With Ti/ Alloy Rails: The Formula FXR is a solid & versatile saddle. This model continues to impress both the MTB & Road sets. After a two-year product development process, our designers crafted a slightly longer shell than many leading saddles & as a result the Formula series offers plenty of room to manoeuver in the cockpit. All of the Formula saddles rely on D2 Edge Flex to ward off discomfort on longer rides. In addition, the Edge Flex eliminates any sharp edges, so the legs wont lose power & maintain smooth spinning motion. Its relatively flat profile features an ample rear section for all body types & its one-piece, embossed micro fibre cover is both durable & stylish alike. Sleek, ergonomically shaped for comfort & performance Nylon fibre composite base with D2 Edge Flex One piece, seamless microfibre cover with embossed graphics Ti alloy rails Dimensions: 285mm x 140mm Weight: 265g
