After having to warranty 4 sets of carbon cranks I made the switch. These are marginally heavier but the piece of mind knowing that I won't have them delaminate at the crank inserts is worth the trouble.
I have found these to be an amazing setup, easy install, easy chainring swaps, no creaks.
Easton fell short on the carbon EC90 but these alloy ones are the real deal!
These cranks offer huge bang for your buck. Light weight and good looks along with an easy system for changing chainrings whenever you want.
