CUSP 28.6MM BMX STEM
Based on the BOX Cusp mountain bike stem, the new 3D-forged Mini Cusp is one of the lightest and stiff-
est mini stems available. It also is the world’s first 28.6 mini BMX stem. The added stiffness of the stem with
the new X-Bar 28.6 significantly improves bike handling while putting more power into the pedal stroke.
Red, Blue, and Gold stems are special order only.
This stem only works with 28.6mm handlebars.
See Page 230 for compatible BOX bar.
