Bontrager's Paradigm R saddle is a win-win. It's light, supremely comfortable, and actually adds to higher sustained performance. Does that make it a win-win-win? The inForm BioDynamics optimize your natural movement and reduce thigh chafe to make you more efficient. To dial in the fit, Bontrager built the Paradigm in three different widths with size specific curvatures that provide a custom fit for your sit bones. With ergonomic features like multi-density foam and a Contour Relief Zone that relives pressure on sensitive areas, you can focus on going flat out fast.
