On the track, you want to save as much weight as possible. This is why we make the E-Line Plastic Pivotal Saddle. The E-LIne Saddle is smaller in size than our Pro Slim Pivotal, and is made entirely of plastic with no padding. The seat easily adjusts with a 6mm Allen wrench. This is the perfect light-weight saddle for both the track and the street. For 2013, the saddle is available in Black, Clear, Clear Blue, Clear Red, Clear Purple, and Yellow.
