Easton EC90 SL Crankarms

Yes. The EC90 SL uses Easton's modular CINCH system, which allows you to easily swap between single and double chainring configurations using a standard 20-tooth ISIS bottom bracket tool.

These cranks are highly versatile and compatible with a wide range of standards, including BB86, BSA 68mm, PF30 68mm, BB30 68mm, BBright, and 386Evo. Because they use a 30mm spindle, ensure your frame's bottom bracket shell is compatible with that diameter.

You will need a 20-tooth ISIS bottom bracket tool to remove the lockring on the CINCH system. This is the same tool commonly used for many external bearing bottom brackets.

They are excellent for both. The hollow carbon construction provides the stiffness needed for road sprinting while remaining lightweight and durable enough to handle the demands of gravel and mixed-terrain riding.

The 30mm spindle increases the stiffness-to-weight ratio of the crankset compared to smaller diameter spindles. This results in more efficient power transfer from your legs to the drivetrain.
