Description

The ALUGEAR AERO chainring pair is designed for Shimano 2x12-speed road drivetrains equipped with an asymmetric 110 mm 4-bolt BCD. It is compatible with Shimano FC-R7100, FC-R8100 and FC-R9200 cranks, as well as their versions featuring a power meter.

Made from 7075-T6 aluminium, the chainrings benefit from CNC machining, enabling a lightweight and precise design. Their specific tooth profile, combined with ramps and shift aids, promotes fast and smooth gear changes, even under load.

The surface treatment by industrial anodisation improves resistance to mechanical impacts and ensures a durable finish. The RAMPED & PINNED design contributes to the reliable operation of the double chainring. The optimal combination of ALUGEAR chainrings is recommended to guarantee the announced shifting performance.
