Rotor 3D Aero TT Crankset

The Rotor 3D Aero TT crank features an aero spider design that creates an awesome look when paired with Rotor Aero Chainrings (sold separately). They are compatible with all 130 bolt circle diameter chainrings and of course both Rotor Q and round rings.

Third generation DTT technology and "Closed System Concept" design lets Rotor manufacture their crank clamps in the closed position reducing stress risers and structural strain. This significantly improves clamping integrity.

The Rotor 3D Aero TT crank is made from an extruded aluminum bar and then CNC machined with three internal chambers running the length of the crank. This Trinity Drilling System allows excess aluminum to be removed from the core while still maintaining structural strength. This design is much stiffer and a significant improvement on earlier Rotor cranks. A 24mm steel spindle enhances rigidity and laser-etched graphics give a nice look.

    I like this crankset so much I want one for my other bike now. I set it up with q rings on my TT bike and noticed I was faster. I also noticed that I had less knee stress and the pedal stroke feels more natural.

    Pros: Better biomechanics, highly compatible, coodesign

    Cons: The q rings are pricey
