ROAD Cranks

 

ROAD

Cranks

Combine the cranks arms with different types of spiders, chainrings and axles. Looking for a power meter? Then choose the INspider, or you can also add it in the future; this is the main advantage of the the modularity of ROTOR cranksets.

 In short, a solution that will adapt to your needs without having to replace the complete set.

If you are one of those who already enjoys one of our ALDHU or VEGAST cranksets, their modularity will allow you to upgrade them to ALDHU Carbon in a very simple way. 

You will only need to purchase the ALDHU Carbon crank arms, since the rest of the components are compatible with our current range of ROTOR road cranksets. 

ALDHU Carbon

 

Lighter, modular and made of Carbon! 

These were the targets for developing the new ALDHU® Carbon cranks. The most loyal fans of our brand had been demanding a carbon crankset for years. ROTOR accepted the challenge with a single goal: We had to improve in all aspects what we had manufactured to date. 

The result? Crank arms that are 100 grams lighter than the ALDHU® aluminum model, leaving the total weight at only 544 grams (170 mm & 50/34t DM chainrings). At the same time, we managed to increase its absolute vertical and horizontal stiffness by  respectively 11% and 36.1%.

ALDHU 

 

Introducing the ALDHU cranks, ROTOR’s lightest cranks ever. The innovative modular structure, together with axles and different chainring options, makes each component individually available to accommodate the current spectrum of riders and bike standards.

The ALDHU incorporates OCP Mount technology, which enables the rider to fine-tune the orientation of ROTOR’s oval Q RINGS. The ALDHU® proprietary, patent-pending design is based on the modularity of each crankset component.

VEGAST

 

VEGAST is the perfectly balanced lightweight yet stiff crankset with similar design features to ALDHU.

VEGAST benefits from ROTOR’s innovative proprietary drive-train features of modular design, OCP Mount for Q RINGS and Direct Mount technologies. Combined with our one piece Direct Mount chainrings which are machine CNC’d from single blocks of aluminum, VEGAST achieves the perfect balance of lightweight and stiffness to take on the most challenging of mountain climbs.

Aesthetics matters

We already know that you want to enjoy your bike and show off with your friends.

Thanks yo our award-winning modular system you can performance your bike with the newest and more innovate chainrings.

Modularity allows you to select the perfect crank, chainring, axle or spider combination and easily install or switch out elements with a simple assembly system.

Q RINGS,

the perfect choice

We love Q RINGS oval chainrings and that is because we care about our health looking for a minimum fatigue and less stress on the knees.

As a cyclists, we also want to improve our performance and our oval chainrings bring us the possibility to adapt our crankset to our pedal stroke, virtually decreasing the gear ratio in the dead spot and increase the gear ratio in the power phase where the rider exerts the most force.
