Easton EC90 SL Crankset

No, the EC90 SL is sold as a crankset only, consisting of the carbon arms and the aluminum spindle. You will need to purchase a compatible bottom bracket and direct-mount chainrings separately to complete your drivetrain.

Yes, the CINCH system is designed for modularity. You can easily swap between 1x and 2x chainring configurations using the direct-mount interface, making this a versatile choice if you decide to change your drivetrain setup later.

The EC90 SL uses the RaceFace/Easton CINCH system with a 30mm spindle. You will need a bottom bracket that is compatible with 30mm spindles and your specific frame's bottom bracket shell standard, such as BB30, PF30, or BSA 30.

While it is officially rated for 10 and 11-speed systems, many riders successfully use it with 12-speed setups. However, compatibility often depends more on the specific chainring you choose to mount, so ensure your chainring is optimized for your 12-speed chain.

At 352 grams for the arms and spindle, this is an exceptionally lightweight crankset. The hollow carbon construction is engineered specifically to shed weight without sacrificing the stiffness required for efficient power transfer.
