The Selle San Marco REGALe was created from the well known REGAL that was used by the worlds greatest riders. This saddle uses a special injection that allows the shell to gradually deform to fit your riding style without compromising structural integrity or performance. This saddle also uses Carbon Fiber Reinforced Plastic to allow for the ultimate mix of comfort and strength. The CFRP also allows the shell to keep its shape while the injection moves around it. To top it off Selle San Marco has given the REGALe Carbon Fiber rails to further reduce the weight.
