The Sky team has switched its trademark color from blue to green to bring attention to the Sky Rainforest Rescue Project, which aims to save a billion trees in the Acre region of Brazil.

The new Pinarello Dogma2: as swoopy as ever
Sky and Movistar's Pinarello Dogma2 machines retain their unmistakably curvaceous personalities but undergo a number of changes that are said to make this new version a little more aerodynamic and lighter, too.
The key structural change is a move to a 1 1/8-to-1 1/2in tapered front end from the previous version's 1 1/4in lower steerer diameter. The fork crown has been beefed up accordingly and it also flows more smoothly into the similarly enlarged – and notably lower – down tube. Taken in total, Pinarello claims a 19 percent boost in stiffness under braking.
In addition, many of the original Dogma's pronounced ribs have been toned down in the interest of improving airflow. Changes in the lay-up schedule supposedly beef up certain sections subject to the most stress while still shedding 30g of weight in total.

Otherwise, Pinarello not only retains the first Dogma's uniquely asymmetrical approach to frame design but perhaps even expands on it. The driveside fork blade and seat stay are visibly puffed up as compared to their non-driveside counterparts, the chain stays are asymmetrical as usual, but even the top tube is slightly shifted over to the right with different ribbing on either side.
According to Pinarello's official marketing line, this "leads to an increase in the symmetrical pedal action of six percent".

Team Sky has also made a fundamental aesthetic change for this year's Tour de France, switching from its characteristic blue to a bright green to draw attention to the new Sky Rainforest Rescue Project. We're not just talking bikes, either – the team kit has been updated, too, as well as all of the support vehicles and online communications.
In cooperation with the World Wildlife Foundation, Sky is looking to raise 4 million Euros that will be used to save over a billion trees in a region of Brazil – and the habitats of the people, animals, and other plants that call that area home.

More clues revealed on Campagnolo's mysterious electronic group
Campagnolo still has yet to officially reveal a shred of technical information on its new electronic drivetrain and while we've been able to figure out various pieces of the puzzle by inspection, there are still many remaining – but a couple fewer now.
As we previously suspected, it appears that the system's rechargeable battery is hard-wired with the rest of the harness and indeed is not readily removable from the bike as Movistar mechanics had a web of extension cords and chargers strewn about their work area at the team hotel Friday afternoon. What does this mean to consumers? Probably not much if the battery life is as generous as Shimano's Dura-Ace Di2 but either way, potential buyers will want to make sure they've got a plug handy wherever they happen to store their bike.
We also assumed earlier that the buttons on the inner sides of the hoods were to be used as remote switches for an as-yet-unseen computer head. As it turns out, they're instead how you enter into setup mode to adjust the derailleur positions. We stood watch as a Movistar mechanic put the final touches on one team bike: push and hold down the button until the LED lights up on the display, then push the paddles to make microchanges in position.
Sorry, folks, that's all we've got. Baby steps…
Truly customized bikes for some Katusha riders
Four Katusha riders have specially customized versions of Focus's Izalco Team frame
Four Katusha riders started this year's Tour de France with starkly finished black Focus Izalco Team bikes instead of the usual – and far more colorful – white, blue, and red livery. As it turns out, these are four structurally distinct frames that Focus created at the specific request of some of its riders.
According to Focus marketing head Herwig Reus, team riders actually have their choice of five different lay-up schedules in total (with one being stock) – all using the same mold so at least on the surface, they're indistinguishable from consumer versions. Reus tells us that on average, the other four variants are about 10 percent stiffer in the bottom bracket but other parameters such as front triangle stiffness and ride comfort vary depending on preferences.
Each frame uses "10 to 15 percent" more carbon fiber to hit those stiffness numbers so the raw chassis are heavier. Since those four customized frames are only covered in decals and clearcoat, though, Reus says the finished weights are about the same (which tells us there's probably a difference of about 100-200g raw).
Reus adds that one or more of these variants might make it into the consumer channels depending on how much practical sense each rider's requests make to the general public. Stay tuned.
