Smoother and Lighter — Easton Crankarm And Spindle Setup

Thanks to a superior utilization of RaceFace Cinch technology, the Easton EC90 SL Crankarms allows for direct mount 1x rings as well as direct mount 2x spiders — perfect for all cyclocross riders.

Constructed with EC90 SL carbon arms and an EA90 SL spindle, this increasingly popular 1x setup is ready for action. The advantages of a setup like this are lightweight simplicity, though it falls short on adaptability. A Cyclocross rider's ability to ride a course, then effortlessly change chainrings to their preferred setup is a major necessity that has, until now, been overlooked.

Easton refines the design for larger ring applications with improved chain retention while reducing running noise and friction. When it's time to upgrade your setup, make sure to include the Easton EC90 SL Crankarms for a bike that runs like a pro through technical segments and tight turns.

Features:

  • Cinch Direct Mount Technology for 1x and 2x
  • EC90 SL Carbon Arms
  • EA90 SL Spindle
  • Cinch Power Meter Compatible
  • Arms come assembled with spindle – rings and BB sold separately

    Great for modular front chainring set up

    I really like the Easton system and I purchased these for a gravel bike build I'm doing this winter. Easton is set up modularly so you can run 1x or 2x and have a variety of chainring options available. I actually purchased a Power2Max chainring/powermeter that is Easton compatible for this set up.
