For nearly three decades, Terry has been working with all levels of riders to solve all types of saddle comfort issues. Introduced in 1999, the Italian-made Butterfly represents the best in all that research and development. The Butterfly Carbon is the lightest of the Butterflies thanks to the addition of carbon rails. It's wider in the rear than typical saddles for good support of a woman's sit bones. The Butterfly Carbon's low profile, flat top and a complete cutaway through the center are designed to provide pressure relief and support in the right areas. Injection-molded foam is used to provide the right balance of softness and stiffness so you won't sink into the saddle the longer you ride.
