Details about the ROTOR INSpider Powermeter:

The CNC milled AERO orifice offers the possibility to use the ROTOR cranks with Aero chainrings as closed Aero cranks for 1- and 2-speed drives. 
The ROTOR INSpider can be placed between the 2INpower and the Inpower. The Spider is mounted on the crank using the ROTOR OCP Direct Mount System without special tools and only with a 10mm hex key. 

The INSpider measures the joint performance of both legs using 4 opposing strain gauges. This provides very accurate data on the performance and clearly shows potentials for improving the pedaling performance. The strain gauges are arranged in opposite directions and the Spider has a temperature measurement and compensates independently for measuring deviations due to temperature.

After each assembly or change of the chainring and at least once a month, it must be recalibrated.

Customer Reviews
Check your frame before you buy
Interference between spider and bottom bracket is severe.
If your frame's BB is bb86 or 386 and gentle tapered around BB, I think it is difficult to install with standard axle. Better to use offset axle.
I can't install to my FOCUS IZALCO MAX DISC with standard axle because of the interference. So I have to use offset axle.
