The SPANK 31.8 Split Stem was created to provide high strength with an ultra-low weight, ideal for trail and enduro applications. As part of our Human Factor Design initiative, the Split Stem features unique incremental sizing options so you can fully tune your ride. 33 / 38 / 43 / 48 mm lengths with a zero degree rise will allow you to dial in that perfect fit.
The Split Stem is shot-peened and anodized for maximum strength and additional durability over non-peened components.
