Options

BCD: This power meter is available in either a 110, 130 or 110 4-Bolt Shimano BCD in order to fit your choice of chainring sizes.

There is also an SL (super light) version of the 110 BCD 4-bolt Shimano which is 30 grams lighter than the regular 110 BCD 4-bolt Shimano version.

Crank arms: You have the option of either ROTOR ALDHU 24 mm crank arms (uses a 24 mm spindle) or ALHDU 30 mm crank arms (uses a 30 mm spindle). In addition, each of these cranks comes in a wide range of crank arm lengths. (We also offer this power meter with ROTOR carbon crank arms for an additional $149.)

Please note – this power meter ships with a Black decal. Please let us know if you would like us to include a different color instead (Red, Blue, White, Green).

 

Professional Assembly (Optional)

We are happy to professionally assemble your power meter crankset if you select this option when ordering. This ensures your crankset is correctly built and saves you time. Professional assembly includes:

  • Mount the power meter to the cranks and tighten to factory specifications
  • Apply multi-purpose bicycle grease where necessary
  • Install chainrings on the power meter (if chainrings are ordered)
  • Apply power2max decal

Please note – while we tighten everything to factory specs, it is still your responsibility to routinely check your power meter crankset to make sure all bolts and nuts remain securely fastened.

 

Tools Needed for Installation

You will need the following tools for installation of this product. You can purchase many of these commonly used tools in our store.

  • 10 mm Allen key

Compatibility

Chainrings: The power fits 110 BCD 5-bolt, 130 BCD 5-bolt or 110 BCD 4-bolt (Shimano) chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.

Please note, the 110 BCD 4-Bolt (Shimano) version is compatible with all Shimano 4-bolt chainrings, including Ultegra 8100 and DURA-ACE 9200 chainrings.

What is BCD?: BCD (bolt circle diameter) is simply the diameter of a circle that passes through the centers of the bolt holes in your chainring. The BCD is usually stamped right on the chainring as either 110 or 130. It is important to know what BCD your crankset is because assuming you want to use your existing chainrings on your new power meter, you need to order the correct BCD.

Bottom Bracket: This power meter fits 24 MM or 30 MM bottom brackets, depending on the version ordered. If you are ordering the same size as you currently have on your bike, you should be able to re-use your existing bottom bracket. However, if you are chaining spindle sizes, you will need to replace your bottom bracket. Please contact us with questions, we are happy to help.

  1. Tyler Coquelin (verified owner)

    been using this unit for about a month now and not only does it look amazing it also works amazing as well. I’ve had a handful of other brands powermeters on my rig and this one is far and away the most reliable and accurate I’ve had to date. I’m not sure when I’ll get a new meter again. Also, love the easy ability to change crank arms if I wanted or needed different lengths for any reason. This unit has it all. If you have any questions about it DM me and I’ll do my best to answer anything you have.

      Awesome! Thank you for the follow-up review, Tyler! Looks like you are enjoying them! Good luck on your rides and if there is anything else we can do, please let us know!

    There are plenty of places to go for reviews about how well these P2M NG and NGeco power meters work so I won’t repeat all that. I’ve had an NGeco for a while now, and that’s part of why I went with this one. They just work, and the Rotor ALDHU cranks are well made, easier to install than just about anything else out right now and available with 24 or 30mm spindles.

    Pulled my Shimano crankset and this slid easily into place. There’s a quick youtube video from P2M covering this and showing just how easy it is. Just slightly out of date but nothing significant, the Rotor cranks now say 35nm vice the 40nm in the video. And the preload collar now takes a 2mm vice the 2.5mm used in the video, or vice versa, I’ve already forgotten.

    Power Meter City as always provided great customer service through good communication, quick order processing and handling. I’ve done business here before and will continue to do so as power meter are a not insignificant investment and it helps to buy from someone with good service.
