absoluteBLACK Premium Shimano 110/4 BCD compatible oval chainrings are designed for new types of Shimano cranks Dura-Ace 9100, Ultegra 8000 and 105 R7000 only. These are the finest oval chainrings on the market in terms of shifting, smoothness of pedaling and manufacturing quality. (They can be also retrofitted to 9000 and 6800 cranks). 10/11/12spd compatible.

Size (Mass +/-1g): 34T (31g), 36T (37g), 39T (42g), 50T (120g), 52T (137g), 53T(139g)

BOLTS: For Outer chainring please order "Long bolts" from us OR Bolt Covers. Changing Inner chainring to oval only? use original bolts.
Material & Finish: cnc machined 7075 Txxx Aluminum. Long-lasting construction. Physical Vapour Deposition
Ovality: Optimized to each size separately. 34T- 6.5% ; 36T, 38T, 39T- 11.4%, 50/52/53T - 10-11.2% ; Timing of 108 -110.5deg after TDC (top dead center) - Ideal for road climbing. Patent Pending.

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