This is why the back of the Absolute Black Oval road chainring does not feature cutouts, like other oval products on the market. Instead, Absolute Black design smooth angled surfaces, to help chain to slide quickly and precisely between chainrings.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan\u003eAbsolute Black outer oval chainrings have 6 up-shifting ramps, for easy and quick gear change, even under load. Each outer chainring also features 12 down-shifting points. Instead of steel shifting pins they use a CNC machined \"ramp and recess\" solution. Special raised ramps work in conjunction with the tooth recesses to stabilize the chain when shifting. Absolute Black oval chainrings DO NOT require any modification to the (standard) front dérailleur in order to work properly.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSize (Weight):\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e34T (30g)\u003c\/li\u003e \u003cli\u003e36T (36g)\u003c\/li\u003e \u003cli\u003e38T (41g)\u003c\/li\u003e \u003cli\u003e50T (122g)\u003c\/li\u003e \u003cli\u003e52T (135g)\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Shimano Dura-Ace 7900,7950, Ultegra 6750, 6700, Shimano 105- 5700, Tiagra 4650, FSA, Rotor 3D \u0026amp; 3D+, S-works and many more older cranks.
