The 2x11 speed chainring made of Easton was subjected to very extensive tests and everything to get everything out what this chainring has to offer. In addition, the Easton shift rings have excellent shifting performance thanks to extensive optimized shift ramps and pins. The spiders feature the Cinch Direct Mount System making a swap between ring sizes or even between double ring configurations a fast and simple procedure. The Easton 2-way chainrings fit perfectly to the EC90 SL crank handle. The Shifting Rings can also be used on other cranks with a 4-arm and 110 mm BCD mount.
