5 Introduction
Thank you for choosing a power2max NGeco power meter. Your power2max NGeco is a quality
product that has been developed and manufactured with great care by the power2max Team. It
offers you precise and reliable power measurement in all weather conditions while being simple and
intuitive to operate. Please read the user’s manual carefully before using and observe the directions
for correct use of your power2max NGeco power meter.
We wish you plenty of enjoyment and success with your power2max NGeco!
5.1 Warning
Please read the user’s manual before installation and operation! Improper installation can lead to
accidents. In case of doubt, consult a professional bicycle mechanic. Observe the indicated torque
values when installing screws and bolts. Screws and bolts that are too tight or loose can damage your
power meter.
Before going on a ride, get to know the functions and operation of your power meter.
Get a checkup from a sports physician before starting your training program.
Pay attention to traffic and road conditions before checking or controlling any data from your head
unit.
6 Scope of delivery
Your power2max NGeco power meter system is made up of:
A specific power2max NGeco power meter (corresponding crank version and bolt circle diameter)
Quickstart Guide with inspection certificate
Packaging
Optional:
Lockring tool to install the power2max NGeco power meter to the crankset
Crankset, bottom bracket, chainring set, chainring bolts as ordered.
IMPORTANT:
Please check that delivery contents are complete and correct.
7 Operation and installation
IMPORTANT:
It is necessary to observe indicated torque values during installation.
You can also find these values in the download area of power2max.com. Screw and bolt connections
that are torqued too heavily or weakly could damage the power meter and impair the function.
In the case of bicycle frames with a BB86 or BB386EVO bottom bracket standard, the compatibility
between the power meter and frame must be tested before installation.

7.1 Necessary tools
In the case of models with lockrings like FSA BB386evo, a specific lockringtool for installing the
crankset to the power2max NGeco power meter is needed.
Depending on the model: medium-strength threadlock (e.g. Loctite 243).
Optional: bench vice to fixate the lockring tool during installation.
7.2 Operation
Your power2max NGeco power meter has an LED indicator light to control its function. This enables
you to easily test functionality and operate the system in a quick and uncomplicated way.
1. Remove the isolation strap by pulling it out of the battery compartment. Check if the battery cap is
in the correct position.
2. Now, the LED indicator light flashes green for approximately one minute.
3. Connect the power meter to your head unit (observe manufacturer’s instructions). As long as the
green LED indicator light blinks, the power2max NGeco power meter is emitting signals that can be
received by an ANT+ enabled head unit. Pair your power meter-compatible head unit with your
power2max NGeco power meter. Observe the respective manufacturer’s manual. Pairing your head
unit is only necessary when operating the power meter for the first time. Numerous power2max
NGeco power meters on different bicycles should be put into operation one after another to avoid
unwanted connections between different power2max NGeco power meters and head units. You can
repeat the pairing of your ANT+ enabled head unit at any time. To do so, you just have to activate
your power2max NGeco power meter by turning the crankarm. Your power2max NGeco power
meter then signalizes its availability for pairing by blinking its green LED indicator light for one
minute.
You need an ANT+-compatible head unit that supports the power-only profile (PWR). For example,
suitable head units are:
CYCLEOPS: Joule 2.0 and 3.0
GARMIN: Edge 500/510/520/800/810/820/1000, Forerunner 310XT/910XT
O-SYNCE: navi2coach, Macro X and Macro High X
You can find a current list of compatible products at the ANT+ Alliance:
http://www.thisisant.com/directory/power2max-road-rotor-3d-plus-bcd-110-or-130/
The data for power and cadence are calculated and transmitted via ANT+.
7.3 Installation
1. First install the chainrings on the power2max NGeco power meter. In the process, take care
that they are aligned correctly and solidly attached in accordance with the respective
manufacturer’s specifications. Guide the large chainring from above onto the power2max
NGeco power meter.
2. Align the holes for the bolts.
3. After you have guided the small chainring onto the power2max NGeco power meter from the
rear, tighten everything with the dedicated chainring bolts.
IMPORTANT:
Observe the torque values prescribed by the manufacturer.
Pay attention to the alignment of the chainrings and bolts. Please adhere to the
manufacturer’s specifications.
4. Then mount the right crankarm to the power2max NGeco power meter. Guide the right
crankarm from the front through the opening in the power meter. Pay attention to the
alignment and the correct fitting of the crankset to the power meter. For models with
lockrings like FSA BB386EVO: place a few drops of medium-strength threadlock (e.g. Loctite
243) on the inner side of the lockring and tighten it with the help of the lockring tool.
IMPORTANT:
Please pay attention that the lockring is correctly seated on the threads.

Lock the lockring tool into a vice. This guarantees that the lockring tool is secure and stable
for further installation: tighten the lockring to the prescribed torque values. You can also find
these values in the download area on power2max.com or ask the crankset manufacturer.
5. Install the entire power meter unit with crankset to your bicycle. To do so, follow the steps in
the installation instructions provided by the crankset manufacturer. If necessary, these can
be requested from the crankset manufacturer or from a retail store. We recommend
checking the correct function of the front derailleur and, if needed, re-adjusting it.
IMPORTANT:
Observe the installation instructions prescribed by the manufacturer.
6. Initial operation and installation of your power2max NGeco power meter is thus completed.
You can go for a ride!

8 Using your power meter
Using your power2max NGeco power meter is as easy as the initial operation and installation is.
8.1 Before your ride
When your bicycle isn’t being used, the power2max NG power meter is in standby. Once the crank is
moved, the power2max NGeco power meter is activated automatically, and it begins emitting a
signal. This is shown by the blinking of the green LED indicator light.
8.2 During your ride
Your power2max NGeco power meter updates the parameters power and cadence in 1 second
intervals; they are transmitted per ANT+ protocols.
8.3 Zero-point adjustment and thermal correction
To ensure a precise power measurement, the zero-point (the measured value when no torque is
present) is automatically determined by your power2max NGeco power meter. The zero-point
adjustment compensates for influences caused by temperature variations and mechanical zero-point
shifts. It is possible to repeatedly set the zero point at the head unit, but it isn’t necessary! This is
performed by the system automatically when it is not under power. “Not being under power” means
a stop in pedaling for at least two seconds during a ride. If a de-powering as described above is not
possible, for example during a long mountain climb, then your power2max NGeco power meter
automatically compensates for temperature. Thus your power2max NGeco guarantees a reliable
power measurement.
8.4 Battery life
Battery life is approximately 400 hours. Battery life can be decreased by low temperatures and by
transporting your bicycle, for example in your car.
8.5 After your ride
Your power2max NGeco power meter independently enters standby mode approximately two
minutes after ending your ride. This reduces electricity consumption and increases battery life.
8.6 Battery change
To change the battery, remove the battery cap. Pull out the empty battery and insert a new battery.
Pay attention to the correct position of the positive pole and negative pole. Close the battery cap and
check if it is in the correct position.
8.7 Turning the power meter on and off
You can turn off your power2max NGeco power meter yourself by removing the battery. You can
turn your power2max NGeco power meter back on by inserting the battery again.
NOTE: When transporting your bicycle, the power2max NG power meter is activated. Therefore, it is
recommended to turn off the power meter for longer transports. You should generally turn it off
when transporting your bike in a plane.

8.8 After a crash
The power2max NGeco power meter was developed to have a high level of reliability. Usually, crash
forces are generally completely absorbed by the crankarms and the bottom bracket. Crash damage
to a power2max NGeco power meter is thus almost completely ruled out.
In the interest of your own security and health, you should do the following checks:
Could the cranks have sustained any damage? The cranks could suffer from hairline fractures that
you may eventually not recognize. This could, over time, result in sudden failure. Therefore,
replacement is recommended. If anything is rattling around the crankset, this could indicate
potential damage. Examine all mechanical connections.
9 Maintenance and care
The battery cap should be checked occasionally to see whether it is seated correctly and, if
necessary, it should be replaced so that it maintains its waterproof seal.
After longer rides in the rain, please examine if water has penetrated the battery cover. Should this
be the case, allow this area to dry out while having removed the battery and with the battery cap off.
You can assist in this process by using an absorbent cloth.
Do not use thinners or solvents to clean your power2max NGeco power meter. Use clear water or
soapy water and a soft sponge or rag.
IMPORTANT:
Do not clean your power meter with a high-pressure power hose!
