Publicado Por En julio 25, 2026 The S&M Credence Turtleneck stem features a topload design that's CNC machined in the USA from a solid block of 6061-T6 aluminum. Based on the original S&M Challenger, the Turtleneck stem features a narrower shape with notched out clamping area to help shed unnecessary weight, chamfered edges, knee-friendly rounded backside, solid chromoly bolts and a machined Credence logo on the faceplate for a distinct look.
