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
Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38, 53/39T
If you wish to use other configurations it will also work, but shifting will be slower and may require more "adjustments" of front dérailleur to be acceptable. Also remember that front dérailleur 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.
One of a kind look
Super stiff design due to thicker, 5mm construction
Bespoke Absolute Black 4 / 6 point ramp and recess shifting design shifts as crisp as original
Finest design that provides excellent strength to weight ratio
If you are only changing the inner chainring - use the original bolts that came with your crank. If you are replacing a pair of rings, you will need a set of regular ‘double’ chainring bolts or our set of Bolt covers (buy bolt covers that are right for your crank model). Tighten all four bolts with a force of about 5-7Nm. Mount your crank back to the bike. If you were changing the outer ring size - you need to also adjust the front dérailleur.
