Rotor Vegast24 Crank Arms

ROTOR crank arms VEGAST for road bike

The Rotor VEGAST crank arms offer a low-cost alternative to the ultralight ALDHU aluminum crank arms. In homage to the successes of the Rotor Pro-Tour riders in the big country tours, the name VEGAST is made up of 3 legendary Grand Tours passes (VEleta-GAlibier-STelvio = VEGAST).

For the greatest possible adaptability, the VEGAST crank system has a modular design. Thus, the chain line for disc and rim brake hubs can be adjusted via 2 different shafts and the 110 mm 4-hole Spider can be exchanged for ROTOR's new Direct Mount chainring combinations. For optimum adjustment of the oval ROTOR Q-Rings chainrings, the OCP system (Optimum Chainring Position) has been further refined. Through a combination of different positions of the crank arms on the crankshaft and a fine-styled Spider recording the position of the chainrings can be adjusted in 1-degree increments. For the adjustment and assembly of the chainrings and the crank, only a 10-millimeter hex key is necessary.

The crank axles are 30 mm outside diameter BB30 and can be driven via corresponding bottom bracket in frames with BSA, BBright (Cervélo) and BB30 bottom bracket.

NOTE: Contrary to the illustration, only the crank arms are supplied. Matching chainrings and crank axles can be found in our shop.
