We understand that not all frames can fit a left side crank arm power meter. But the good news is…you still have options…
Right Side Crank Arm Power Meter
Stages Cycling makes a right side crank arm power meter for Shimano Ultegra R8000 and 8100 as well as DURA-ACE 9100 and 9200.
With right side units, frame clearance is not an issue so you would be good to go with these. These cost a bit more than the left side power meters, but they also come with a brand new set of chainrings.
Pros: Affordable, easy to install, don’t have to change crankset
Cons: Measures right leg power only
Other Power Meter Options
In addition to the right side units above, we have some crankset and pedal options for Shimano that you can find in our article here: I have a Shimano road crankset. What power meter will work for me?
Please note, at the top of the article there are left side crank arms but if you scroll down, you will see the other options we are referring to.
