Great showing by Columbia this tour and entire season (High Road) for that matter.
The stages of the TdF so far are as though they were designed for the strengths of their riders - rolleur stages with a flat sprinter stage thrown in Cavendish/Ciolek to do their thing. Plus their absence of a true GC contender gives their riders the freedom to really go for it in these stages (i.e. they dont need to hold things in reserve, as much as the teams with GC prospects).
Those kits are very fred though.
