I have a Shimano road crankset and can’t fit a left side crank arm power meter. What are my options?

Well 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 R8000 and DURA-ACE 9100.

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

 

Crankset Power Meter

There are several great power meter cranksets we recommend for Shimano users.

This is a new crankset (power meter spider, crank arms and spindle), excluding chainrings. power2max makes wonderful power meters. They measure both left and right leg power, are reasonably priced and are as good as it gets in terms of reliability. If you select the 24MM spindle option, it will fit your current bottom bracket exactly like your Shimano crankset (no need to change bottom brackets). In addition, if you select the Shimano 4-Bolt spider, you can even use your Shimano rings on it.

ROTOR INspider ALDHU Road Power Meter Crankset

This too is a new crankset (power meter spider, crank arms and spindle) and can be purchased with or without chainrings. The INspider measures both left and right leg power, comes in a variety of crank arm lengths and can be set up in a 1X or 2X chainring configuration. This power meter can also be purchased with a 24MM spindle so it will fit your current bottom bracket without any changes. You can use your current Shimano chainrings on it or buy new ROTOR rings.

Like the power2max above, this is spider-based crankset and it’s a wonderful option as well. You would purchase the DFour Power Meter spider as well as Quarq DZero DUB crank arms. At $595, this is quite a bargain for a high-end power meter and carbon crankset. Unlike the power2max however, you must change your bottom bracket. Specifically, the DFour requires a SRAM DUB Bottom Bracket. They are relatively inexpensive, but it does make installation a bit more involved.

The power meter is designed for use with Shimano DURA-ACE 9100 chainrings. Shimano Ultegra R8000 and 105 R7000 rings also work. However, they don’t match the color of the power meter as nicely.

Pros: Moderately priced, VERY reliable, measures both legs
Cons: None

 

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
Cons: None
