The dual-side power meter features a small unit on the spider of a Shimano Dura-Ace R9100 crankset and is adorned with the iconic 'S' of Specialized.
On the non-drive side, a strain gauge sits on the inside of the crank in a similar style to other leading power meters.
Interestingly, Sagan's bike had a 4iiii power meter on his non-drive side crank, while his teammates are equipped with both sides of the power meter from Specialized. Although the Bora-Hansgrohe mechanic assured us that this was due to time constraints ahead of a training ride. 4iiii provided the Bora-Hansgrohe team's power meters during the 2017 season.
Specialized have long been rumoured to be producing a power meter and join component giants Shimano in introducing its meter to the WorldTour for the 2018 season.
Shimano claim that six WorldTour teams will be using their power meter this season, eclipsing the formerly prominent SRM and replacing Stages and Pioneer for Team Sky and Sunweb respectively.
Bora-Hansgrohe have opted to pair the new Specialized power meters with Wahoo Elemnt Bolt head units, and use K-Edge out-front mounts.
Last weekend, new S-Works shoes and an updated aero helmet were seen at the Australian national road race championships in Ballarat.
The majority of the Bora-Hansgrohe team were all equipped with the new shoes from Specialized in an eye-catching fluoro orange to yellow fade, and some riders also opted for the new aero helmet in Bora-Hansgrohe colours.
BikeRadar has contacted Specialized for a comment regarding their new power meter and will update this story with their response.
