Swage Alloy Direct Mount MTB Stem 40mm BlackThe Swage Direct Mount stem is an aggressive DH stem designed to be lightweight, extremely strong and flow perfectly with the lines of today's downhill bikes. Every chamfer and cut out not only creates a beautiful stem but also cut out any unnecessary weight to make it race and freeride ready. The Swage direct mount stem has a 40mm length and features a 35mm bar bore that is extremely torsionally stiff and mates up perfectly to our Mandrel bars.
