Product Description:

Left INpower crank arm as an upgrade kit for all Rotor Flow cranks with 30mm Axle.

Define your optimal pedal performance, whether you're a climber, sprinter, pacer, or all three.
The way you exert power throughout a single pedal rotation varies in force, even more when you are seated, standing, sprinting or pacing. Define your pedal performance with INpower's TORQUE 360 and OCA pedal analysis and then apply it to Q-Rings to commit to your full potential.
Sophisticated metrics 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. Inconspicuously integrated inside the crank axle, INpower is protected from shocks, crashes and outside contaminants plus it allows you to maintain your bike's sleek, elegant aesthetics.
OCA Knowing your OCA (Optimum Chainring Angle) will allow you to align Q-Rings' maximum gear ratio with your maximum force output.

UBB. Universal Bottom Bracket. INpower cranks are compatible with almost every bike frame in the market.

NEW features optimized for Q-Rings. TORQUE 360 and OCA (Optimum Chainring Angle) help cyclists precisely and accurately analyze force variations in their pedal stroke.

User-friendly software. INpower software features different modules to optimize cycling performance.

Integrated electronics inside. Electronics and battery are integrated inside the axle, making INpower shock and contaminant resistant, and waterproof with cleaner data transfer.

Tool-free battery replacement. INpower uses a standard AA battery that typically lasts 300 hours when fully charged. A rechargeable AA battery can also be used.

Compatible with all ROTOR 30 mm cranks. INpower's axle-based technology offers a wide range of cranks for both road and off-road riding.

 

It's aero shape has been specifically designed from a purely functional perspective in performance and not just aesthetics using the Computer Fluid Dynamics (CFD) Design. CFD is a software program that can simulate an actual wind tunnel test and allows Rotor to isolate a specific part of the bicycle in motion. The rigidity of the Rotor Flow is not compromised, as it is 10% stiffer than most aero cranks on the market.

The aero profile of the crank arms has been optimized according to the varying airflow the crank encounters from the axle to the pedals, throughout the 360° pedal stroke. The crank arms and the spider are designed separately in order to acquire a maximum advantage of the crank's aero profile.

The crank arms of the Rotor Flow are made of 100% cnc machined, 7075 T6 aluminium which have been trinity drilled for a further weight reduction. Rotor's axle systems has been specifically developed for multiple BB systems. In addition Rotor has extended the compatibility of the Flow because now it's featuring an improved ultra stiff 30mm aluminium UBB axle.

This crank is manufactured using an improved version of RotorŽs proprietary "Trinity Drilling System" technology during manufacture. Due to the larger axle-crank contact area of a BB30 crank, all three holes can be drilled from the axle side of the crank arm, allowing further optimization of wall thicknesses. It improves both the weight and the weight-rigidity ratio of the crank arm.
