SRM SRAM S975 System

The SRM S975 power meter is available in BSA/GXP or BB30 crank arm combinations. The power meter incorporates the SRAM S900 series crank set made exclusively for power meter devices. Combined with SRM's accuracy and durability, the SRM S975 power meter delivers world-class performance for serious cyclists!

Each individual SRM power meter is exclusively manufactured upon order in Jülich (Cologne), Germany, resulting in a delivery period of approximately two weeks.


As its predecessors the PC8 is reduced to the need of the athletes and does not come with usless gimmicks.

The PC8 also features GPS (for recording). The backlight as well as the GPS can be turned off in order to prolong battery lifeup to 45 hours. With a storage capacity of 500 MB, the PC8 has the ability to record about 4,000 hours of training. A built-in motion sensor turns the PC8 on automatically when riding.

Since many users have several bikes with power meters, it is now possible to define four bicycle profiles and select the respective before departure. The previously necessary pairing before departure is not required any more.

The display is user configurable. The shell is made of anodized aluminum, which is available in three different colors: red, black and titanium.
