This is the Terry Butterfly Cromoly Saddle. The ultimate bike seat for women, ridden and universally loved around the world. For two decades, Terry has been designing and testing saddles with female athletes, distance riders and recreational cyclists. Introduced in 1999, the Italian-made Butterfly represents the best in all that research and development. Wider in the rear than typical race saddles for good support of a woman's sit bones; completely cut away through the nose and mid-section, making it flexible and comfortable against soft tissues; low profile, flat top with multi-density injection molded foam that's a bit stiffer in the rear for more power while pedaling; ti-nox rails are super light and super strong; textured leather wears beautifully over time and keeps you in position. Black or white leather with gloss butterfly graphic and patent leather rear.
