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. - Black leather with gloss butterfly graphic and patent leather rear - Signature Butterfly cutaway through the center of the saddle for pressure relief - Length x width: 262mm x 155mm - Weight: 218 grams; 7.7 ounces - Rails: lightest weight Carbon 10mm H (+/- .5mm) x 7mm W (+/- .5mm) note: check seat post for compatibility as it may require an adapter kit (available from some seat post manufacturers)
