The way you exert power throughout a single pedal rotation varies in force, even more when you are seated, standing, sprinting or pacing. Manufactured in Spain from 7055 aluminum through state-of-the-art CNC-machining, the INpower 3D+ 130 BCD features sophisticated metrics to interpret your data through user-friendly software and advise you when to turn up the pace, ease off the pedals, do another interval or call it a day. Seamlessly integrated inside a compact crank axle, the INpower 3D+ 130 BCD is protected from shocks, crashes and outside contaminants, plus it allows you to maintain your bike’s sleek, elegant aesthetics.
