Transition to oval.
The outer ring gets all the attention with its aero design and flashy style, but you can't complete the transition to ovals without a Rotor Shimano Inner Q-Ring. This little ring proves that the quest for improved pedaling efficiency expands beyond the high-speed gear mashers, garnering benefits on small ring recovery days and long, grinding climbs alike to eek a few extra watts out of every pedal stroke.
- Complete your ovalized chainring setup with this inner chainring
- Aluminum construction balances low weight and stiff power transfer
