The Rotor 3D Plus Road Crank is compatible with BBright, BB30 and BB30 pressfit framesets. It is supplied with chainring nuts and bolts, two 11.5mm spacers and one 1mm spacer. Use one 11.5mm spacer on each side for BB30 installations. Use one 11.5mm spacer on the drive side and the 1mm spacer on the non-drive side for BBright installations. Complete directions are included.
The Rotor 3D Plus 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 30mm alloy spindle reduces weight and enhances rigidity. The laser-etched graphics give a nice look. The 3D 110 BCD cranks are compatible with any 110mm bolt circle diameter chainrings.
Please note: chainrings and bottom bracket bearings and seals not included
