Description

The ALUGEAR AERO Mono Chainring 12V is designed for road, time trial and gravel drivetrains in 1x12 speed. Its compatibility with Shimano cranks with 110 BCD asymmetric 4-arm spacing allows fitting on Dura-Ace R9200, Ultegra R8100 and 105 R7100 models.

Made from 7075-T6 aluminium, this chainring benefits from optimised CNC machining to minimise weight while maintaining appropriate strength for its intended use. The anodised surface treatment provides protection against mechanical impacts and a durable finish.

The Narrow Wide tooth profile, specifically designed for single chainring setups, promotes excellent chain retention, reduces noise and minimises wear. Compatible with Shimano HG+ 12V, SRAM Flattop 12V and KMC chains, it is used exclusively in 1x setups without a front derailleur.
