Stages Rival Wattmåler

Stages powermeter for the SRAM Rival crankset. The Stages powermeter is pre-assembled in the non-drive side crank arm, which is mounted as a substitute for your original crank arm. The Stages Rival crankarm also fits other models such as the SRAM Force or Red (GXP 24mm axle). As the powermeterunit can only be installed in aluminium crankarms, the Stages powermeter is not available as original carbon crankarm of SRAM Force or Red.

The Stages power meter measures the transferred power accurately(± 2% deviation) The power meter is very lightweight and small because this unit is mounted in the crank arm. In comparison to a normal crank arm it is only 20g heavier. That is why the Stages unit is the lightest power meter on the market, with a difference of 33-185 g compared to competing powermeters and all of that for the best attractive price.

The data transfer uses ANT + and Bluetooth Smart technology, which makes all your favorite head units compatible, and upgrades your firmware wireless using your phone.
The cadence is measured wireless and without additional sensors, using the intern accelerometer. The data that is displayed is without a filter, the competitor does have to add a filter to display accurate data.

Mantel only has the new production batch of the Stages Powermeter. Problems due to bad batterycovers belong to the past.

Note: check if your powermeter is compatable with your direct mount rear break, underneath your bottom bracket.
