Technology: TDS, UBB System, INPower

Manufacturer’s Notice: Only use the included crank bolts with INPower crankarms. The bolts for other crankarms without INPower have a longer thread, which leads to damage to the electronics.

Features:

– power measurement electronics and battery integrated into the axle
– data transmission protected against dirt and impacts, waterproof to IPX7 standard
– tool free battery change
– firmware updates
– warning when battery is almost empty
– connection of the crank to the PC via USB ANT + stick (Garmin 010-01058-00 or other ANT + dongles)
– installation requires 8 mm and 2 mm Allen wrenches

Information on system requirements and how to use with the Rotor software can be found in the Rotor INPower user manual.

Technology:

TDS
Rotor´s CNC-machined cranks feature the Trinity Drilling System, which is a process that drills three full-depth holes along the axis of the crank. This allows them to remove excess material from the crankarm resulting in a lighter crank without compromising its exceptional stiffness-to-weight ratio.

UBB System
Rotor’s “UBB” is a super-standard that encompasses all BB standards. It allows installation of almost any 30 or 24 mm axle crank from Rotor on the bike you have, regardless of its BB type.

INPower
Multi-discipline power meter integrated inside the crank axle where it is protected from impact and external contaminants. Because power is measured in the left leg through two sets of opposing strain gauges placed in the axle, cyclists who already own a current set of Rotor cranks can purchase the left crank arm independently. Proprietary metrics TORQUE 360 and Optimum Chainring Angle combine with ANT+™ protocol metrics including cadence, torque effectiveness and pedal smoothness to provide precise data about your power output. INpower uses a standard AA battery, which can be easily replaced without tools wherever AA batteries are sold.
