Easton EA90 Spider/Ring Assembly 52/36 4B 11spd Parts - Chainrings

EA90 Spider/Ring Assembly 52/36 4B 11spd

$144.73
Easton direct mount rings use a new narrow/wide design specifically tailored to road/cx/gravel applications.

The individual tooth profile has moved from the traditional symmetrical shape to more directional specific design with the intention to create a positive chain roller engagement to help with chain retention, critical to prevent chain slip and bounce over rough terrain.

Combined with taller teeth the Easton narrow/wide ring can be used without a chain guide or clutch derailleur.

Wide-tooth material has been removed from each side to reduce running noise and drag when running at extreme edges of the cassette.

Combined with additional material removal at the base of the teeth ensuring excellent mud shed and chain retention in the muddiest of CX conditions.

To connect the outer ring to the Cinch interface an asymmetric four arm shape allowing for larger stiffer arms in the power zones of the pedal stoke and an overall reduction of weight with thinner arms in pedaling zones that experience less torque.

All Easton rings feature the Cinch Direct Mount System making a swap between ring sizes or even between double ring configurations a fast and simple procedure.

Using the Cinch DM System also provides a significant weight savings by eliminating the material overlap and extra bolt hardware that is required for a traditional spider with chainring configuration.

The rings have 47mm chainline with the Easton 129mm spindle, the optimal chainline for 135/142mm rear hub spacing which covers all road/CX disc bikes.

47mm chainline gives full access to all gears on your rear cassette with efficient power transfer and minimal running noise.
