Rotor 3D+ Power Cranks (175mm 130BCD 527g)
Praxis WORKS – LEVATIME 53/39 Chainrings

ROTOR’s patented POWER meter crankset will improve your training quality and experience. Measuring both cranks arms individually ROTOR Power is able to provide information that other power meter cannot.
The crank is the result of combining the technology of two reliable and proved products: ROTOR 3D+ cranks and AIP’s measurements system MEP.
ROTOR Power is not just another power meter, in fact it is 2 power meters in one. Adding only 30 grams to the standard 3D+ MAS crank, is the lightest power meter in the Market.
Compatibility with ANT+ devices, easy battery replacement, UBB30 axle and MAS spider are also benefits of the ROTOR Power.

The UBB (Universal Bottom Bracket) system allows ROTOR 24 and 30 mm axle cranks to be installed in almost any frame in the market.

MAS stands for Micro Adjust Spider and in Spanish means “MORE”. And this is all about, ROTOR MAS Spider offer even more adjustability options of our Q-Rings. Thanks to its extra holes, ROTOR OCP system is multiplied by two giving the rider more precision to adjust his ROTOR Q-Rings.

ROTOR’s Twin Leg Concept was created with the idea of a balance crank set. What is the point of an ultra-rigid right crank if the left one is not that stiff? By designing a crank set as a “real set”, not just as two individual crank arms, TLC creates the most blanced crank sets in the market.

ROTOR’s CNC crank arms are stiffer than the competitors’ products due to their Trinity Drilling System. This process drills three full-depth holes from axle to pedal, leaving behind a box- trellised structure, similar to bridges structures. This gives their crank arms superior stiffness without adding more weight to the cranks getting an exceptional stiffness-to-weight ratio.
