General classification hope Andy Schleck (RadioShack Leopard Trek) is riding a prototype Bontrager saddle, dubbed the Serano, at the 2013 Tour de France.
BikeRadar have been told that the model is super light and based on the American company’s current range-topping inForm Team Issue. The principal differences between the two saddles appears to lie in the shape and material choice. The Serano has a full curved back as opposed to a cutout V. Underneath, a reinforced carbon shell and carbon rails replace the titanium stays used on the Team Issue.
Given the shape and curved nose, the Bontrager Serano seems to have been designed for riders with a high degree of flexibility. While the all-white prototype is mounted on Andy Schleck’s competition Trek Domane, his spare bike carries the production model of the saddle.

A release date and exact weight are still to be confirmed by Bontrager.
