absoluteBLACK Premium Shimano 110/4 bcd compatible oval chainrings are designed for new type of Shimano cranks Dura-Ace 9100, Ultegra 8000 & 105 R7000 only. These are 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), 38T (41g), 39T (42g), 50T (120g), 52T (137g), 53T(139g)

Ovality: Optimized to each size separately. 34T- 6.5% ; 36T, 38T, 39T- 11.4%, 50/52/53T – 10-11.2% ;

Timing of 108 -110.5ﾰ 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 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.

Occasionally, without notice, manufacturers change product design and/or specifications.
