How the absoluteBLACK Oval Chainrings Shift?

Показать описание
Both, inner and outer absoluteBALCK Oval chainrings are optimised with smooth shifting in mind. This is why the back of the absoluteBALCK 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. Specially 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 to work properly.
