Advice From Our Staff:

This power2max is a great way to add power to a ROTOR or VEGAST crankset. It measures power from both legs, is accurate and very reliable. We believe the price also represents a good value for what you get (even for this more expensive NG version). We highly recommend power2max power meters and use them on many of our own bikes.

 

Options For This Power Meter

BCD: This power meter is available in the following BCDs in order to fit your choice of chainring sizes:

  • 110 5-Bolt | 130-Bolt | 110 4-Bolt | 110 4-Bolt SL

Note – The SL (super light) 110 BCD 4-bolt version is 30 grams lighter than the regular 110 BCD 4-bolt version.

 

Other Versions to Consider

ALDHU NGeco Version: While the NG version you are viewing here features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics, we also sell the more affordable power2max NGeco ROTOR ALDHU Road Power Meter.

NG ALDHU Complete Crankset: If you would like to purchase the power meter plus crank arms, we have the power2max NG ROTOR ALDHU Road Power Meter Crankset.

Compatibility

Cranksets: The power2max NG ROTOR ALDHU Road Power Meter is compatible with all 24 mm and 30 mm ROTOR ALDHU and VEGAST cranksets.

Chainrings: The power fits 110 BCD 5-bolt, 130 BCD 5-bolt or 110 BCD 4-bolt 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 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.

    Only had it about a month but I am very pleased. Previous power meter dropped out all the time. This one has been solid. The install was also very easy.
