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 & Track versions. Choose your set-up from ROTOR’s one-piece Direct Mount Q RINGS® or Round chainrings, or classic spider with oval or round chainrings.
Our Direct Mount technology features a proprietary spline interface connecting 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 eight-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.
When to use the Offset Axle: The Offset axle is recommended for use with Shimano GRX drivetrains, particularly GRX front derailleurs. Other than in the case of GRX drivetrains (which have a chainline slightly outboard of most other groups) the Offset axle is typically reserved for disc-brake drop-bar bikes with tire clearance over 50c.
NOTE: Price is for VEGAST crank arms only, and will require an axle and chainrings. Every crankset is custom in its modularity -- make it yours!
