Vegast Cranks
*Only crank arms are included. If you also need the spindle choose it here.
The ROTOR Vegast Cranks are our best value to upgrade the drivetrain of your road, gravel or triathlon bike. Forged in 6082 aluminium and CNC machined, these cranks will help you to decrease the weight of your bike. Besides they feature Trinity Drilling System® technology, which lightens the crank arms through three longitudinal hollow holes alongside of the crank arm. Thus we get rid of raw material excess to deliver an extraordinary stiffness-to-weight ratio.

TDS® — Engineered differently
The Trinity Drilling System (TDS®) is ROTOR’s exclusive machining technology that transforms our aluminium crank arms through a precision triple-drilling process. The result is a crank arm that is lighter and stronger, but above all delivers unmatched stiffness. Superior to any aluminium or carbon crankset on the market and only comparable to the very best titanium cranks.




Outstanding durability and anti-corrosion protection alloy
These crank arms are manufactured from 6082-T6 aluminium alloy, offering an excellent balance of strength, durability and corrosion resistance. Designed to withstand high pedaling loads, they provide reliable performance in all conditions and are particularly adequate for high humidity environments.




Spindle options: compatibility or performance
Vegast cranks stand out by giving you a choice of spindles. Choose the 24mm steel spindle for seamless compatibility with Shimano® bottom brackets. Or, step up to our 30mm spindle: made of 7075-T6 aluminum, its thicker design makes it both lighter and stiffer. Select the perfect option for your setup.
