To get to the new EC90 SL, Easton took the best elements of their proven MonkeyLite SL and punched the gas a little. OK, a lot. They refined the TaperWall butting, added strength and toughness to the Easton mountain composite and refined the shape of the EC90 to make it the clear choice for XC and All-Mountain riders looking for a bar that's as light as a tick and as tough as a truck.
