absoluteBLACK Round Premium Shimano Dura-Ace/Ultegra Chainring - BLACK

absoluteBLACK Premium Shimano 110/4 BCD compatible ROUND chainrings are designed for new and old types of Shimano cranks like Dura-Ace 9100, 9000, Ultegra 8000, 6800 & 105 R7000 and more.
These are the finest round aftermarket chainrings in terms of shifting, stiffness and manufacturing quality. 10/11/12spd compatible. Made in EU

Important
Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38, 53/39T
If you wish to use other configuration it will also work, but shifting will be slower and may require more "adjustments" of front derailleur to be acceptable. Also remember that front derailleur can only accept max 16T difference between 2 chainrings - this is how Shimano and SRAM designed them.
Absolute Black always recommends using a new chain when fitting new chainrings
