ROTOR Bike Components is proud to present its ultra rigid and lightweight 3D+ crankset, based on the successful 3D crank, designed to complement Cervélo’s proprietary BBright standard perfectly.

rotorbike.com

ROTOR 3D+ is a light-weight aluminium, purebred performance crank:470 g for 170/110 BCD (w/o BB and chainrings).

3D+ cranks have an improved version of our proprietary “Trinity drilling system” technology. Due to the larger, 30 mm diameter axle-crank contact area of a BBright crank, all three holes can be drilled from the axle side of the crank arm, allowing for further optimisation of wall thicknesses, improving both the weight and the weight-rigidity ratio of the crank arm.

Certified to EN 14781 standard.

Mount the assembly of the two pedal-spindle adaptors, the two cranks, the chain-wheel set, and the bottom-bracket spindle locate on its normal-production bearings. Incline the cranks at 45° to the horizontal.

Apply repeated, vertical, dynamic forces of 1 800 N alternately to the pedal-spindle adaptors of the left- and right-hand cranks at a distance of 65 mm from the outboard face of each crank for 100 000 cycles. The direction of the force on the right-hand crank shall be downward and that on the left-hand crank shall be upwards for a rearward-pointing crank or downwards for a forward-pointing crank. The maximum test frequency shall be 25 Hz.
