Building on what it learned with its Gen 2 Version, Stages has developed its technology even further for this latest model. Built on to a Shimano Dura-Ace R9100 crankset, it measures the power output of each of the rider's legs and the crankset is individually calibrated to ensure its accuracy. Stages produce power meters that both avid amateurs and professionals at the top of their game can trust. Reliable Readings In All Conditions To ensure consistency of measurement, Stages introduced a world-first feature to its power meters. This feature is called “Active temperature Compensation” and it is built in as standard to account for sudden temperature changes, which if not accounted for, would result in false and inaccurate data. Stable Connection Stages have made additional improvements to the Bluetooth and ANT+ transmitters and the accelerometer. This ensures a stable and powerful connection with your cycle computer is maintained and a faster sampling rate for more up-to-date feedback on your performance.
Simple to use Auto Zero: every time you stop pedalling for 3 seconds or more your power2max "re-zeros", no need to re-zero manually. No cadence magnet needed: you dont need to install a cadence magnet on your bike. Your power2max calculates cadence precisely using its internal accelerometer. Batter change: when the time come to change your battery - after 300 to 400 hours of use (6,000 to 12,000km) - you can do it yourself. ±2% Precision Power2max power meters deliver state of the art data: they achieve an accuracy of ±2% or better including all environmental influences. power2max power meters achieves this accuracy through a refined design and high quality manufacturing processes. Designed, engineered and made in Germany Power2max manufactures the power meters in Germany with the highest quality production standards. ANT+ Power2max power meters use the ANT+ standard to transmit data wirelessly to your bike computer. The ANT+ standard guarantees reliable transmission and offers a large number of bike computers to choose from. Bluetooth ready Power2max FSA power meters are Bluetooth ready and can be upgraded to transmit the data wirelessly not only with ANT+, but also via Bluetooth communication (with purchase of firmware upgrade). Upgradeable Power2max FSA power meters can be upgraded to have the software feature of left-right balance

The Hollowglide construction ensures high rigidity while its hollow structure cuts down on weight yet maintains strength. This provides better power transfer and quicker and more precise front shifting performance. Hollowtech II Forged Crank Arms A lightweight crankset not only reduces the bike’s weight but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the HOLLOWTECH crank. Just like high-quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight. The Best Balance of Stiffness, Strength and Weight The concept of Hollowtech II technology is focused on producing a superior crankset that will maximize a rider’s power transfer. The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedalling stability, allowing for more efficient power transfer.
