Rotorís Eggrings promise increased power output at the sweet spot in your pedaling stroke while minimising the dead zone. Unlike other elliptical chainrings currently out on the market, Rotorís rings are tunable to match a riderís particular power output profile. Thankfully, the Eggrings are also pinned and ramped to retain quality shifting. Road and mountain versions are both available.
