Look Wattmeter EXAKT Dual is the result of a collaboration between two market-leading companies, Look and SRM. Although it incorporates the latest electronic system, a new generation of miniature electronic components, the pedal remains lightweight, weighing just 155 grams. The carbon body offers unparalleled stiffness, while the 400 mm² of stainless steel contact area optimizes power transfer.Spring tension can be easily adjusted from 9 to 18. All of the SRM's technological elements are enclosed in a steel axis, so sealing has been taken very seriously. The axis, which integrates an oversized ball bearing and a needle bearing, is sealed with a blue cap on the outside and a double system on the inside. The IPX6/7 certification makes the EXAKT pedal suitable for even the toughest racing conditions. ACCESS TO DATA TO MAKE YOUR PROGRESSPOWER - measuring power independent of environmental factors, allows you to effectively manage your training, define your training zone and accurately track the development of your performance. CADENCE - this is the number of pedal strokes that are made in one minute. In other words, pedaling speed. Combined with the force you apply to the pedals, it indicates the power output. TORQUE ANALYSIS - measure the left and right torque for each pedal stroke to know the maximum and minimum values, as well as the smoothness of the pedaling. BALANCE - the balance function, available on the DUAL version, provides separate power output from the right and left foot. This will give you accuracy when analyzing performance. Also measured: normalized power, torque efficiency, intensity factor, training stress score...
