Last time we went on a big bender with a bag of stems the RIP 3D was the find of the bunch and the latest one is still as good.
The chunky cut forged big bore body and sturdy clamp wall thicknesses is a total rock in terms of handlebar stiffness. It's backed by Titec's no questions asked guarantee for the first two years too.
The chromed front plate on ours had some slightly sharp edges, so we'd get in there with emery cloth if you're running it with carbon bars. Otherwise though it's a super tough, reasonably light all rounder at a great price.
