About the Easton EC90 ALX Crankset

The lightest crank Easton has ever made and one of the strongest on the market, delivering uncompromised all-road performance. EC90 ALX crank arms, inserts and spindle were engineered from the ground up to eliminate every possible gram of material, and address rider pain points. Easton maximized power transfer, minimized weight, increased heel clearance, and incorporated unscuffable protection. Lighter, stronger, and built to perform wherever the road takes you.

All-Road Wear Plate

Shaped and placed through rider sampling and imagery overlap to locate crank body areas most impacted by heel rub and long-term wear, delivering unique functionality for all-road riders. 

Many Lengths Made Light

Carbon fiber layup is bonded with ultralight inserts through a proprietary process and resin system, achieving infallible durability and strongest in test. Lite-spline (LS) spindles and redesigned arms shave weight by reducing bulk. Five arm length options round it out to ensure this crank is fit for all.
