Popular Rotor VEGAST Crankset w/ Chainrings, 4-arm, Q-Rings, 110 mm BCD

Made for the steepest climbs: the VEGAST Crank by Rotor

With the VEGAST crank, Rotor commemorates the three historic victories of Rotor athletes in the Grands Tours – Tour de France 2008, Vuelta a Espa帽a 2011 and Giro d’Italia 2012. The name is composed of the highest climbs of these legendary tours: VEleta – GAlibier – STelvio. With VEGAST, you can face the steepest mountains.

The innovative modular system of the VEGAST crank allows you to adjust every single component to your bike setup and your physique.
Direct Mount technology consists of a special interface that connects the crank arm, axle and chainring, so that you can easily mount and dismount the VEGAST with only one bolt.

In combination with Q-Rings, the OCP Mount technology allows you to adjust the optimal chainring position (OCP) in 1-degree increments, allowing you to precisely set your individual OCP. Maximise your performance while respecting your riding style.

The VEGAST crank features the Trinity Drilling System with three internal holes from the axle to the pedal. This gives it a particularly low weight and at the same time superior stiffness. With VEGAST you need not shy away from any challenge.

Technology:

TDS
Rotor CNC cranks are stiffer than competitive cranksets thanks to 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 the stiffest possible crankset by balancing the left-right stiffness of the cranks. 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 contributes to the best balanced cranks available.

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.
