Description of Rotor 3D24 Track 144 BCD Crank

The 3D24 Track crank is featuring a striking aero spider design with light reinforced structure increases stiffness and improves aerodynamics. The crank arms of the Rotor 3D24 Track are made of 100% cnc machined, 7075 T6 aluminium which have been trinity drilled for a further weight reduction. Rotors axle systems has been specifically developed for multiple BB systems. In addition Rotor has extended the compatibility of the 3D24 Track because now it's featuring an improved ultra stiff 24mm aluminium UBB axle.

Please note: The Rotor 3D24 Track 144 BCD crank is only compatible with the also available Rotor BB Track Steel Bottom Bracket Cups!

This crank is manufactured using an improved version of Rotor´s 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.

The 3D24 Track crank can be used with Rotor Q-Rings (not included in delivery) and also with any chainrings with 144mm bolt circle diameter.

The hight specified justage of the cup pretension is achievable because of an compression ring with nut.

Q-Factor: 147mm, Chain line: 43.5mm
