Shimano 105 5800-L 53T 110mm BCD 11-Speed Chainring - Compatible with 53/39T Crankset - Black - Perfect for Road Biking & Performance Cycling Upgrades

Both the inner and outer chainrings were returned in the same packaging but I have only been refunded for the inner chainring.Unfortunately, the outer chainring was not compatible per cycle store. I thought various combinations of chainring sizes were compatible with Shimano 105.
