Rotor Vegast Modular 30mm Crank Arms

When dreaming up the new Vegast cranks, we thought it only appropriate to pay tribute to ROTOR's racing heritage and commemorate our three historic victories of the Grand Tours — Tour de France (2008), Vuelta España (2011) & Giro Italia (2012). Honoring three of the highest climbs of these iconic races, the Vegast is named after the Veleta, Galibier, and Stelvio, with an understanding of the sheer power and stamina needed to take on the steepest climbs of cycling.

Much like our new Aldhu crankset, the Vegast is designed with a modular system, that allows you to select each crank component based on your unique bike setup and physical characteristics and includes both Road and Track versions. Choose your set-up from ROTOR’s one-piece Q RINGS® or Round Direct Mount chainrings or classic spider plus oval or round chainrings.

Our Direct Mount technology features a proprietary spline interface connecting the crank arm, axle, and chainring allowing you to easily assemble and disassemble your crankset with only one bolt. Combined with Q rings, OCP mount technology allows you to adjust your Optimal Chainring Position (OCP) to within one-degree increments to precisely configure your unique OCP to maximize power output to your distinct pedaling style.

- Crafted using expert CNC processes, Vegast includes our Trinity Drilling System, with three internal holes from axle to pedal, giving the dual benefit of an exceptionally light crank with superior stiffness to take on the most challenging rides.
- Modular forged 6082 aluminum arms with an exceptional stiffness-to-weight ratio
- OCP direct mount rings allow the rider to configure to their optimum chainring position for maximum power transfer
- Axle spindle spacer DM rings (1x/2x) and bottom bracket options available separately
