power2max makes spider-based power meters for the road, MTB, gravel and track. These are some of our favorite power meters. They are accurate, durable and worry free. Many staff bikes here at Power Meter City have power2max power meters on them. You can buy these power meters as a stand-alone spider that you bolt onto your current crankset, or as a complete crankset (power meter plus new cranks). These power meters feature dual-leg power, left/right balance, Bluetooth SMART and auto-zero, among other features. power2max power meters fit virtually every crankset, including SRAM, Cannondale, FSA, ROTOR, Specialized, Easton, Race Face, Shimano, Cane Creek and more.
Additional power2max Power Meter Info:
power2max makes two versions of their power meter: NGeco and NG. The NGeco is the base version that is more affordably priced. The NG is the premier version. The NG features slightly better accuracy, a rechargeable battery, a longer warranty and some additional training metrics. Please see the chart at bottom for a full breakout.
If you purchase a power2max spider, installation requires that you remove your current crankset, replace your spider with the power2max and reinstall your crankset. In addition, for certain cranks, a power2max Lock Ring Tool is necessary to remove the spider. If you purchase a complete crankset, you simply remove your current crank and install the new one.
power2max power meters spiders weigh around 150-180 grams depending on the version and size. When buying a power meter, you should focus on added weight. Therefore, be sure to subtract the weight of your current crank spider in order to determine the added weight of the power meter. You’ll likely find the weight added by the power2max spider is minimal.
power2max power meters measure power at the spider. Therefore, they are able to measure power from both legs. In addition, they feature left/right power balance. With this, the power meter can tell you how much power is being generated by each leg. Power balance comes standard on the NG models, however it’s a paid upgrade on the NGeco models.
What really stands out for the power2max is its accuracy and durability. These power meters provide good power meter data week in and week out, which is what you want from your power meter. In addition, you can get up to a five-year warranty on the NG.
The NGeco power meters use a CR2450 battery. Battery life is around 300-400-hours, which is very good for a user replaceable battery. The NG power meters use a rechargeable battery and gets about 150 hours of battery life.
All power2max power meters have both ANT+ and Bluetooth SMART. Therefore, they can be used with any bicycle computer, smart phone or tablet. You can also use them with indoor training apps such as Zwift.
NGeco power2max power meters are accurate to within +/- 2.0%. This is in-line with the industry standard in regards to power meter accuracy. The higher priced NG power meters are accurate to +/- 1.0%. This is very accurate for a power meter.
Like most power meters, the power2max uses an accelerometer to measure cadence.
The NGeco power meter comes with a two-year warranty. The NG power meters feature a five-year warranty. The warranty covers the product from defects in material and workmanship.
