Easton | Lite-Spline CINCH Spindle Kit | LS Wide

The wider foundation for a proper gravel drivetrain.

The Easton Lite-Spline CINCH LS Wide Spindle connects EC90 ALX crank arms to Shimano gravel drivetrains with the spacing needed for modern GRX and CUES chainlines.

Its shorter wave-taper interface allows the EC90 ALX crank arms to use shallower spindle inserts. This removes unnecessary material from the crank arms, reduces weight, and increases heel clearance.

The LS Wide spindle is optimized for both 1x and 2x GRX chainlines and supports a broad range of road and gravel bottom bracket standards.

Important Compatibility Note

This LS Wide spindle is designed exclusively for Easton EC90 ALX crank arms. It is not backward-compatible with previous-generation Easton crank arms.

Crank arms, chainring, bottom bracket, and crankset spacer kit are not included.
