The EA90 crank is the newest member in the family of Easton CINCH powertrain components. With a variety of 1-way and 2-speed chainring variants and a large selection of inner bearings, the aluminum crank arms are suitable for a wide intended use : from Gravel bike and Cyclocrosser to purebred racing bike, the crank can be configured with the preferred gear ratio.

The CINCH modular system allows you to adjust the crank in no time. The right crank arm can be disassembled via an integrated puller with a hexagon key and the chainring exchanged with a commercially available bottom bracket key for cartridge bearings, or replaced with a double spider. The crankshaft and the left crank arm can remain in the frame.

Available are the EA90 crank arms with crank lengths of 170, 172.5 and 175 millimeters.
