Rotor’s Ovalized Chainrings
FRIEDRICHSHAFEN, Germany – Rotor claims its product is completely different from the gone but not forgotten Biopace chainrings. A decade ago, they debuted courtesy of Shimano but didn’t last.
Now Rotor is bringing back ovalized chainrings and they do is differently. The Spanish parts maker’s Optimum Chainring Position (OCP) allows varying the point where the ring resistance is bigger; adjusting to the moment when the rider applies the maximum strength.
Rotor offers Q-rings and QXL for road that have 5 OCP regulation points while MTB rings have only 3. QXL are Q-rings with greater ovalization, a complementary option for those already using Q-rings.
