Rotor VEGAST 24 Crank Arms

Item number: 82939

The Rotor VEGAST road crank arms for 24 mm axle diameter can be combined with oval or round single or 2-speed chainrings, where mounting is done either via Direct Mount or via a Spider. The name VEGAST is made up of three legendary climbs from the great Vuelta, Tour and Giro races: VEleta - GAlibier - STelvio. In combination with Q-Rings, OCP mount technology allows you to adjust the optimal chainring position (OCP) in 1-degree increments, allowing you to precisely set your individual OCP.

Technology:

TDS
Rotor CNC cranks have a particularly high stiffness due to the Trinity Drilling System (TDS). In this procedure, three full holes are drilled from the bottom bracket to the pedal. This creates a box-like grid, similar to a box girder bridge. This makes the cranks extremely stiff while at the same time reducing weight, resulting in an excellent stiffness-to-weight ratio.

Twin Leg
Rotor's Twin Leg Concept (TLC) offers particularly stiff cranksets by balancing the left-right stiffness of the crank arms. A super stiff right crank arm is of little use if the left crank arm cannot keep up. By designing the pedal cranks as a set instead of two separate crank arms, TLC offers the best possible balanced cranks.

OCP Mount
The exclusive Rotor technology OCP Mount stands for biomechanical optimisation of the pedal stroke when using Q-Rings. OCP Mount allows you to adjust the alignment of the chainring on the crank in 1 degree increments. The shape of the axle allows independent positioning of the crank arms and Spider or Direct Mount chainring, changing the relative position so that the optimum setting can be found for the user.
The multiple positioning possibilities of OCP Mount allow a super fine adjustment of the OCP (Optimum Chainring Position). This makes it possible to prevent or eliminate knee problems, to optimise the effectiveness of the crank rotation or to improve the traction on the MTB and cyclocross.
Position your chainrings with Rotor's OCP Mount System to get the most out of your ride.
