Rotor Bike Components has been known to push drivetrain technologies, like their 13-speed, hydraulic shifting system, but their newest chainring development opens up chain compatibility via a "Universal Tooth Pattern".
These 7075 alloy chainrings are compatible with any 11- and 12-speed chains from KMC, Shimano, SRAM, and most other major manufacturers. The idea comes at a suitable time, since sourcing brand specific 12-speed chains could be tough due to supply constraints. A laser-etched logo on the back of the chainring identifies the Universal Tooth Pattern.
Universal Tooth Pattern Chainring Details
