You have a couple of options for your RS510 crankset as outlined below.
Left Crank Arm Power Meter
While there isn’t a specific RS510 crank arm power meter, you could absolutely use the R7000 power meters made by 4iiii and Stages as the R7000 uses the same interface (Hollowtech II) as the RS510.
Please note, the color of the crank arms won’t be exactly the same (a cosmetic issue only), but most customers are ok with this.
You swap out your current left crank arm for the new power-equipped one and you are good to go.
Please note, whenever you are installing a left side power meter crank arm, you need to confirm you have 10mm of clearance between the left crank arm and the chainstay in order for the sensor to clear. Please see the image below.
Pros: Affordable, easy to install, don’t have to change crankset
Cons: Measures left leg power only
Power Meter Pedals
Power meter pedals can be installed on any crankset. We have several models to choose from.
Pros: Easy to install, works on any bike, can move from bike to bike, don’t have to change crankset
