Inspider, Inpower, and 2INpower: 3 variations of Rotor powermeters. Inpower for discovering power measurement, Inspider for versatility and mounting performance, 2INpower for absolute precision
Vegast INspider, Aldhu INspider, Aldhu Carbon INspider... Make your own Rotor INspider crankset with the features that you need. INspider is a spider powermeter that measures power in the spider. The accuracy is excellent and can be compared to a dual sided powermeter. The only difference with a dual sided is that balance is calculated and not measured. Balance is less precise on INspider than on 2INpower. However the large choice of arms, arm lengths, arm materials, 24/30mm spindles and chainrings make this technology the best seller of the Rotor Powermeter line.
INpower is a competitive powermeter with a single side measure, left only. That's enough to manage your pace during a ride, a climb. You get the access to the whole choice of Rotor chainrings for a reasonable price.
2INpower & 2INpower SL powermeters. They have both 4 pairs of strain gauges, a 30mm spindle and and internal battery. SL is lighter.
