Seemingly no stone has been left unturned in a bid to save precious watts for Rigoberto Uran at the Giro d’Italia. The first thing that strikes you is seriously cool matte black finish with berserker green logos. This isn’t just fashion – save for a single thin layer of laquer, the paint has been removed in order to lower the frame weight by over 200g.
Cannondale are not sponsored by Shimano, but the bike is fitted mostly with Dura-Ace Di2. The lack of sponsorship means that the team is able to use non-Shimano components where they like, without upsetting the Japanese brand.
For example, Uran is using a waxed chain, that is said to save around six watts and an aero burner cage with oversized jockey wheels, that is estimated to save something in the region of 1.5 watts.
To save weight, the cranks are the super light, but very stiff Cannondale Hollowgram SiSl2 with an SRM power meter on the bottom bracket, while the chainrings are 56-44t. This is to maximize chainline efficiency when in the 56-17 gear and make sure that Uran is not spinning out on any descents.
Cannondale told us that Uran has done a lot of testing in the off season riding around velodromes and in wind tunnels, looking at his position to really optimize and lower his drag coefficient.
