Overview
The Spank Split Stem is a highly weight-optimized trail and enduro stem designed for 31.8mm handlebars. Micro increment size options cover every riding style, with the cockpit setup index lasered onto the stem to help riders tune upsweep and backsweep. A chamfered bar clamp reduces stress risers and increases handlebar fatigue life, while an ultra-short stack height and true zero-degree rise deliver a low, aggressive front end.
