How do Power2max powermeters work?
Our power meters work in the same manner as other crank-based systems on the market. Power2max replaces the spider between the crank arm and chain rings with a unit that measures torque, and thus power. The Power2max spider uses strain gauges to measure torque and transmits data wirelessly via ANT+.
Can I also view torque?
With the Type S we directly transmit the power value and not the torque, since the torque value varies across the rotation of a crank. However, with the new NG, torque values are now transmitted via Blue Tooth and ANT+.
How often will I need to change the battery?
Typically speaking, batteries will need to be replaced every 300-400 hours of use depending on the temperature. Click here to see a video of the Type S battery installation. NG power meters have an expected charge life of 150 hours before needing to be recharged.
Which values do Power2max powermeters measure?
Type S power2max measures power, cadence and left-right balance and transmits the values to ANT+ compatible head units. The NG transmits all of the same values as the Type S as well as torque and pedal smoothness.
What kind of software can I use to analyze my data?
There is a large number of solutions available on the market. You can use the software that comes with your bike computer (e.g., Garmin Connect), you can use a third party desktop software (e.g., WKO+, GoldenCheetah), or an online program (e.g., www.trainingpeaks.com).
Does Power2max need a magnet to determine cadence?
power2max power meters don’t need a magnet to calculate cadence as the power meter calculates it internally.
Can I clean the sensor with a pressure washer?
Cleaning with a pressure washer or steam cleaner is not recommended. We generally recommend cleaning with warm soapy water.
Is my frame compatible?
The compatibility of your frame depends primarily on your bottom bracket. Typically speaking, if your frame has a threaded BB, BB30, or PF30 bottom bracket you choices are fairly unrestricted. On certain frames with BB86 or BB386EVO bottom brackets the sensor may collide with the frame so only the BB386EVO power meters will work. If you are unsure which power meter is best suited to your bike, please find out what kind of bottom bracket the bike has and then contact us. You can also check the bottom bracket standards page to see how you can test this.
Can I use my existing crank?
You can use your existing crank if it has a removable crank spider and if we have a compatible sensor for it. For road bikes we have sensors for the following cranks:
– Cannondale Hollowgram
– Rotor 3D, 2D, 3D30, 3D+, 3D Flow, and 3DF
– Specialized S-Works and FACT
– SRAM S90, S950 and Force22
Please also see our five-step guide for more details.
What is a removable spider?
Photos coming soon.
I have a Specialized FACT crank, which power meter should I choose?
Specialized recently changed the design of their FACT cranks. Due to an increased width, Specialized S-Works and FACT cranks made in 2016 and after are compatible only with our NG power meters (Newer cranks are pictured on the left versus older cranks on the right).
Can I use power2max with 11-speed drive trains?
Yes, power2max power meters are compatible with 11-speed drive trains. All you need are 11-speed compatible chain rings for your power2max.
Please note that original Campagnolo chain rings are only compatible with Type S Campagnolo models.
What kind of bike computer do I need?
For the Type S you need an ANT+ compatible computer that reads power data. In our shop we have a number of options that includes the Garmin Edge 520 and 1000. If you’re not sure what you can use, check out this reference and look for the function PWR. The NG is both ANT+ and Bluetooth compatible so you can also use your smart phone or Polar computer.
Is Power2max Bluetooth compatible?
Our NG power meters are Bluetooth compatible though our Type S are not. For a partial list of compatible head units please see above.
Can I re-use my FSA chain rings?
This is a question that we get asked a lot and sadly the answer is no. Even though you may be getting an FSA crank, the OEM chain rings that come with your original crank (FSA, Cannondale, and Vision) will not work with after-market cranks. In fact, sometimes even the after-market FSA rings won’t work with after-market cranks…The issue is with the small chain ring, when you try to install it you’ll find that the chain ring deforms and does not sit flush with the power meter. As the rings are engineered to work as a closed system it’s not something you can substitute for another brand either, which makes the big ring useless as well.
How accurate are Power2max powermeters?
We calibrate our power meters using a custom built torque sensor that has an accuracy of ±0.1%. We achieve, and guarantee, precision of ±2% or better throughout all environmental influences with the Type S and ±1% with our NG power meters.
Do I need to recalibrate my power2max if I change the crank or chain rings?
Changing cranks or chain rings does not affect calibration. You can also use oval chain rings (e.g., Rotor Q-Rings, Osymetric, etc). Please note: compact (110 mm) aero chain rings (such as Rotor aero Q Rings) are only compatible with Type S and NG models, not power2max Classic models.
How can I calibrate my Power2max myself?
There are two important values for the precision of crank-based power meters: zero-offset and slope. The zero-offset is the value that the power meter reports when there is no torque, i.e. when you are not pedaling and there is no tension on the chain. The slope indicates how much the measured value changes as torque increases.
power2max power meters automatically update the zero offset when you stop pedaling. Anytime you stop pedaling long enough (approximately 3 seconds or more) power2max updates the zero offset. You can also update the zero offset manually through a compatible head unit.
The slope does not need to be calibrated by the user. Other systems require calibration in two cases:
1. When you change chain rings
2. Due to aging of the materials of the power meter
power2max power meters have been designed in such a way that you can change chain rings without having to recalibrate the unit. Calibration remains unaffected by the choice of chain rings and chain bolt torque. We do however, recommend tightening chain bolts to the prescribed torque.
Furthermore we have constructed power2max power meters in a way that aging of materials is not an issue. You don?t have to worry about the calibration of your power2max.
If you want to verify the calibration of your power meter anyway you can send it in for calibration. However, we don?t see this as necessary.
Another possibility is to conduct a dynamic calibration yourself: you can compare the values from your power2max with a CYCLUS 2 professional ergometer. This ergometer also has a known precision of ±2%. Please contact us for a comparison test protocol if you wish to conduct this test.
The power values on my Power2max seem low compared to other power meters I use. Do I need to send the unit in for calibration?
As the inverse relationship between the cost of power meters and the number of competing manufacturers continues to grow, the accessibility of data is far more available to the average rider. However, with power values varying from one platform to the next, it’s hard to know which power meter’s data to rely on.
While the simple solution is to stay within one brand or, to a higher degree of extremism, rely on the values of one power meter, this isn’t realistic given the different training requirements of athletes. And, though the root function of all power meters is to measure the power output of the rider, it’s important to remember that different power meters arrive at that number in different ways. That is to say that we expect the values to differ to some degree.
At the foundation of the Power2max philosophy is the concept that force vectors vary depending on the situation, in much the same way that the aerodynamics of a wheel vary over the course of a ride. Therefore it is our belief that dynamic calibration is the only true test of accuracy. To that end we’ve created a dynamic calibration device that measures power outputs in ascending and descending value. A procedure that is done with every Power2max power meter sold. We do appreciate your concern and are happy to escalate our investigation into your power meter’s accuracy if needed. However, to minimize the amount of time you are, or might be, without a power meter we’ve developed a test that you can do to determine if your power meter’s power values are outside where we would expect them to be.
Here’s what you’ll need:
- The weight of you and your bike (in kg)
- A hill at least 1.5km long and 5-6% in grade
- The actual length of the hill
- The height difference (altitude gain)
- And total time
Once you’ve conducted that test 3 times and collected that information visit this site.
Insert the values where indicated and press “Calculate Power”
The “total power (due to 98% efficiency)” should give you a value that is +/- 10 watts from the value given by your Power2max power meter. If it is, breathe easy, all is well. If not, you’ll need to contact us further as we’ll need to send the unit to Germany for further testing.
