Shimano Dura-Ace FC-R9100 Inner Chainring

Anodized and with a durable aluminium construction, this chainring attaches to your crankset using a 110mm bolt circle diameter and uses a 4-arm asymmetrical setup for supreme rigidity and stiffness. Compatible with 11-speed setups and for use exclusively in 34/50 tooth chainset systems, this is a neat and precision engineered option for taking on the road ahead.

A Hollowglide construction for vastly improved weight savings, the tooth shaping on this chainring assures you of a quick engagement and a neat pickup, allowing you to forge ahead with the assurance that your replacement part will work at the same rate as your original part.
