The Metra Stem has a taller 30mm rise and a super wide faceplate with larger head bolts to allow the bars to be really clamped down and prevent them from ever slipping. A favorite feature of ours is the STC (Shark Tooth Clamping) system, which allows the knurling on the bar to bite into the stem even harder and keep them in place, even after the burliest of drops or big gaps. This really is one stem you can trust. Available in Oversize (OS) 25.4mm (pictured) clamping to fit our Strangler, Chocolate, Dive and other 25.4mm bars.
