AITKEN S4 EVA

> Mr. Mike Aitken just spent a week in SoCal, so we decided to take the opportunity to remind you that, like Mike, Aitken's signature S4 stem is strong, classic and proudly USA born and bred. Mike runs it flipped... you should run to your local bike shop and grab one if you like supporting good dudes.
