Description


The cranks are CNC machined from a block of aluminum.
Three holes are formed in each of the cranks to obtain a lighter pedal among the market . With this special manufacturing process, named " Trinity Drilling System" , the ROTOR engineers have managed to get a very light pedal while retaining excellent stiffness .
 
3D + has a shaft diameter 30mm aluminum bottom bracket that provides increased rigidity.
The more refined cranks and lighter than 3D also improves rigidity.
The assembly system was also reviewed here since the coupling nut is on the side of the transmission.
On the other side , a nut adjusts perfectly to the game to get a perfect rotation of the pedals.
 
3D + crank aero differs from standard 3D + by the star MAS makes the most aerodynamic pedals, and allows a perfect setup Q -Ring allowing setting half position , not on the stars ( flanges ) classics.
Star Micro Adjust Spider ( MAS ) and offers more positions for the Q-Rings to meet the requirements and needs of each rider.
 
OCP (optimal position of the plate ) to this star has a setting for every 2.5 degrees of adjustment between positions ( unlike conventional + / star - 5 ° position).
The Q -Ring alone offers five positions and now with MAS , there are 5 more .
 
MAS allow the Q -Ring to be possible in the most comfortable position , whether you are sitting or dancer , rib or a sprint.
