ROTOR’s Twin Leg Concept boasts the stiffest possible crankset by balancing the cranks’ left-to-right stiffness. There is no point in making an ultra-stiff right crank arm if the left crank arm doesn’t
measure up. By designing the cranks as a real set — not just two individual arms, TLC offers the most-balanced cranks possible.
Hydraulic Smart – By using hydraulics in a smart way, benefits gained include frictionless, smooth shifting activation, lightweight, and low maintenance.
Technology applied – Science added to help the rider
EU product – EU cycling and manufacturing expertise
Precision – Gear indexing is placed where it makes the most sense
Computer Numerical Control (CNC) machining provides a precise and consistent manufacturing process. This is especially important when it comes to crafting bike components in order to ensure
flawless funcionality with respect to all the parts working together. Equipped with the latest CNC resources, ROTOR parts are precisely machined to within a hundredth of a millimeter.
7075 aeronautic-grade aluminum alloy offers superior physical properties with which to craft
components like our signature Q-Rings, REX 3 and 3D24 cranks.
To build the best cranks, we start with the best materials
7055 combines the superior physical properties of a 7000 alloy series with incredible fatigue resistance. Every single bar of raw material is checked by ultrasonic inspection to guarantee it free of internal
defects. 7055 is used to craft our 100% CNC machined cranks, like the FLOW, the 3D+, and the REX 1.
Bluetooth® Smart (LE) is the power-and-application-friendly version of Bluetooth that was built for the Internet
