absoluteBLACK Oval Premium 110BCD 5 Bolt Double Chainring

Our Premium Shimano 110/5(bolt pattern) oval chainrings are designed for pre 2014 cranks like Shimano Dura-Ace FC7900, Ultegra FC6750, Shimano 105 -5750 and many more with 5 bolt fitting. 

These are the finest shift-able oval chainrings on the market. Both, inner and outer oval chainrings are optimised with smooth shifting in mind. This is why the back of the Absolute Black Oval road chainring does not feature cutouts, like other oval products on the market. Instead, we design smooth angled surfaces, to help chain to slide quickly and precisely between chainrings. Absolute 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 we use a CNC machined "ramp and recess" solution. Special raised ramps work in conjunction with the tooth recesses to stabilise the chain when shifting.

Our oval chainrings DO NOT require any modification to the (standard) front derailleur in order to work properly.
