QO Bike Chainrings are built for efficient power transfer, precise shifting, and long-term reliability across road, gravel and MTB setups. Though QO is a newer name in drivetrain components, its founders – Pablo Carrasco and Ignacio Estellés, the engineers who created ROTOR – bring decades of experience developing some of the most advanced chainring systems in cycling. Their new brand continues that work with updated materials, tighter tolerances and performance-driven design.
More QO Bike Chainrings Info
Each QO Bike Chainring starts from a precision-machined alloy blank to deliver minimal flex under load and consistent engagement with the chain. The RACE series adds aero shaping for improved airflow and higher-speed efficiency on road bikes, while carefully profiled teeth keep front shifting smooth under power. The GRAVA and ROCKS chainrings use narrow-wide tooth designs to retain the chain in 1x systems even on rough terrain. Both mount directly to QO or ROTOR crank interfaces for a clean, lightweight setup that keeps chainline optimized and installation simple.
Product Families
- RACE – Double chainrings for road riders who want quick, precise front shifts and efficient pedaling at high cadence.
- GRAVA – Single chainrings designed for gravel conditions, balancing mud clearance with strong wear resistance.
