Bontrager Serano RXL Carbon Road Saddle

Model 433183

The throne of the world's fastest

Serano RXL utilizes inForm BioDynamics achieving the optimal combination of fit and efficiency for aggressive road riding or riders with a high degree of flexibility. Oversized carbon rails and a carbon-composite shell keep it ultralight and supportive.
