While his teammates are almost all aboard the Scott Foil, Orica-Greenedge‘s Esteban Chaves is one of a small group of featherweight climbers within the peloton who stick with more traditional lightweight frames whatever the terrain.

Esteban Chaves’s choice is the Scott Addict. A size 54cm version of this frame weighs just 800g, putting it among the lightest bikes on the market. However, Chaves rides an extra extra small 49cm bike with a frame that weighs significantly less than that, meaning that if the team mechanics built it up in the same way as they do the rest of the team’s bikes, it would come in significantly under the UCI’s 6.8kg weight limit.

To make the bike heavy enough for their man to not fall foul of the commissaires, the mechanics have used an aluminium stem and matching handlebars, but have also been forced to put weights in the down tube in order to add a little bit of extra ballast.

As Orica-Greenedge is sponsored by Shimano, Esteban Chaves is using Shimano Dura-Ace Di2, with sprint shifters on the inside of the deep classic round Pro handlebars to help the Colombina change gear when riding in the drops. The wheels are also from Shimano, being Dura-Ace C50s that are used by a number of teams in the WorldTour peloton.

We haven’t seen hide nor hair of Shimano’s new power meter since spotting it at Challenge Mallorca early this year, so Chaves is wired up with an SRM power meter. The only other bits of kit that stray from the Shimano theme are the Continental Competition Pro Ltd tubular tyres and the Fizik Antares saddle.
