The X1-Stem is a heavy duty folding stem specifically designed for bikes and e-bikes using BMX handlebars or similar. It is The Strongest, Safest Folding mechanism you’ll need for your bike! The X1 is made from High Strength Alluminum Alloy (7075-T6), which is double the strength of the standard Aluminum (6160 / 6160 t6). The same alloy used for Aircrafts, Rifles, etc. The design of the X1 doesn’t involve welding, this makes it stronger as the Forged aluminum piece is shaped by using Computerized CNC Milling. We are promoting the product thru prelaunch.com and Soon on Indiegogo.com!
