Chris Froome made his season debut at the Herald Sun Tour this week, and while the event’s defending champion got off to an underwhelming start, he won the race to be the first WorldTour rider to compete with a full Shimano Dura-Ace Di2 9150 groupset.

While Froome did not participate in the Tour Down Under, opting for a training block instead, his Sky teammates debuted the new Pinarello Dogma F10 at the WorldTour opener. The F10s were equipped with parts of the latest Shimano Dura-Ace Di2 9150 groupsets, but due to a shortage of chainrings and wheelsets, the majority of the team used Dura-Ace 9070 cranks and 9000 series wheels.

At the Herald Sun Tour, Chris Froome’s Pinarello has the full 9150 groupset, Osymmetric chainrings and 9100 series wheels, making him the first rider to compete with the full complement of the new component group.

The non-Shimano 52-36 chainrings look similar to the Osymmetric chainrings Froome usually races on. However, they feature a unique step-down design. Froome opts for 175mm cranks with a Stages power meter on the left crank. The bike also has the latest 9100 series pedals from Shimano.

Froome rides on the new Dura-Ace wheelset. Danny Van Poppel was the first high-profile rider on the 9100 wheels, placing fourth on the 60mm hoops at the final stage of the Tour Down under. The new wheels come in 24mm, 40mm and 60mm rim depths, with the 60mm quick-release carbon road tubular wheelset weighing in at a claimed 1,400g. Team Sky has also been racing the 9100 wheels this week at the Dubai Tour and Volta a la Comunitat Valenciana.

Shimano unveiled the new groupset at the 2016 Tour de France, and while more than six months have passed, only Team Sky (full groupset and wheels), FDJ (crankset, power meter) and Bahrain-Merida (front brake) have been seen using the new components.

Team mechanics during the Tour Down Under suggested they expect to fully equip their teams with the groupsets in time for the spring Classics, though it remains to be seen whether all of the 14 WorldTour teams that use Shimano components will receive the groupsets and wheels from the component giant.
