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.

Wider in the rear than typical race saddles for good support of a woman's sit bones; completely cutaway through the nose and mid-section, making it flexible and comfortable against soft tissues; low profile, flat top with injection molded foam that's stiff enough to give you more power for pedaling. - Debossed butterfly graphic - Textured leather cover - Signature Butterfly cutaway through center of saddle for pressure relief - Length x width: 262mm x 155mm - Weight: 248 grams; 8.7 ounces - Rails: ti-316
