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.

Other Versions to Consider
power2max 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 Road Power Meter.
power2max NG Complete Crankset: If you would like to purchase the power meter plus crank arms, we have the power2max NG ROTOR Road Power Meter Crankset.
Cranksets: The power2max NG ROTOR 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.
The 110 BCD 4-Bolt version is compatible with all Shimano 4-bolt chainrings, including Shimano 12-speed 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.
