SRM Shimano 7950 Powermeter: The SRM Shimano 7950 Powermeter was designed for Shimano 7950 series 10 speed users and more specifically, Di2 Electronic users. Electronic shifting systems make gear changes faster and virtually eliminate missed shifts, but the forces on the chain rings are much higher than with mechanical derailleurs.

With this in mind Shimano developed the Dura Ace 7950 chain rings which are 20% stiffer than previous rings. This not only benefits the shift, but also in power transfer from the crank arm through the spider and into the drivetrain. If you ride Shimano Dura Ace 7950 mechanical or Di2 electronic, you will benefit from increased power transmission!
