Komet Butterfly II.  The Butterfly II saves weight with an aluminum ring attachment point which travels freely on the fully replaceable bridge. The belt and leg loops buckle with a smooth-action quick release. It is a fully modular saddle, meaning you can replace the leg loops with the optional batten seat to turn this Butterfly into a Dragonfly saddle. The bridge is also easily replaced. The Butterfly II features two small steel rings and three nylon gear loops. Complies with CE and ANSI standards. Weighs approximately 4 lbs.
