Combining aluminium and carbon fibre opened the door for our engineers to make this one of the stiffest stems on the market. Weight is impressive, too, at 140 grams. Easton has learned a number of tricks along the way to make the best stems on the market, and that experience shows with the EC70 SL stem. We leverage our exclusive TaperWall™ technology and a touch of titanium hardware and our proprietary Distributed Stress Technology and Top Lock faceplate to boost performance. And of course the EC70 SL stem will make any bike look a lot sleeker.
