Cyclingnews has discovered that several FDJ riders at the Tour de France are using the new Shimano power meter that was presented by the Japanese brand on the eve of the race along with the new Shimano Dura Ace disc brake mechanical and Di2 electronic group set. The devices Cyclingnews spotted are a final prototype without any kind of Shimano logo on them. The final product is expected to arrive on the market later in the year.
Cyclingnews spotted four riders with a prototype model of the power meter on their Lapierre bikes as they carry out final testing in the extreme race conditions of the Tour de France. However, FDJ team leader Thibaut Pinot is not one of them. FDJ is sponsored by SRM this season and the French team does not want to risk any problems with Pinot’s bike during the Tour de France.
Pinot will continue to use a SRM power meter.

The Shimano power meter is built into the new Hollowtech II Dura Ace crankset that again has a chunky four-arm design. The power measuring ‘brain’ sits between the arms of the cranks, much like the Pioneer power meter used by the LottoNL-Jumbo team.
Another measuring device is on the left crank, with the two connected via the hollow bottom bracket.
Power output can be determined individually from each leg, as well as information on cadence, giving what Shimano says, its the "truest measure of performance, isolated from external factors such as gradient, road surface and wind".
