Can I install a Quarq or power2max power meter on my Shimano road crankset?

This is a question we get frequently and unfortunately the answer is no. Shimano road cranksets (image below) have an integrated spider. Or said differently, the drive-side crank arm and spider portion of the crankset are one solid piece. This means, it would be physically impossible to install a spider-based power meter on these cranksets.

However, for Shimano users, we suggest the power2max ROTOR ALDHU Road Power Meter Crankset.

This is a spider-based power meter that comes on a ROTOR ALDHU crankset. In addition to being a great all-around power meter, here’s why it’s great for Shimano users:

1) If you select one of the 24MM ALDHU Crank sizes, this power meter will come with the same spindle size as your current Shimano crankset and will fit your bottom bracket without any changes. This makes installation a breeze.

2) In addition, if you select the 110 4-Bolt Shimano BCD option, you can also use your current Shimano chainrings on it.

 

Quarq DFour DUB Power Meter

The Quarq DFour crankset will also work, however please note:

1) This power meter requires a SRAM DUB Bottom Bracket, so you will need to install this in place of your current Shimano bottom bracket

2) The DFour is designed for use with Shimano DURA-ACE 9100 chainrings. Shimano Ultegra R8000 and 105 R7000 rings will also work, however they will not match the shape or color of the power meter as nicely. This power meter is not recommended for use with Shimano 12-speed chainrings.
