PRO PLT Ergo Alloy Road Handlebar. Shimano's PRO line of components certainly deliver plenty of product at an affordable price and their PLT Ergo Alloy Road Handlebar is no exception. Featuring double butted 2014 series aluminum, this handlebar hits the trifecta of being lightweight, stiff, and strong. What differentiates this bar from others in the PLT line up is the ergonomically shaped top section whose flat, broad profile is exceptionally comfortable. There's a recessed channel underneath the ergo section to route cables while the compact bend makes shifting hand positions a quick, simple endeavor.
