The ALLIED Integrated Stem is a fully internal system designed in tandem with our fork to completely conceal the cables while still using a standard headset, allowing the rider to easily swap stem lengths, and it works with a growing list of handlebars designed with integrated cables in mind. The system is the simplest and most user friendly on the market. The cables run through a channel on the top of the stem and are concealed by a faceplate, top cap, and the steerer tube. The ALLIED Integrated stem comes in 10 sizes from 70-120mm in 10mm increments in -8 degree and 0 degree rise. The ST03 stem is MADE HERE in our Bentonville factory. A 100mm stem weighs 184g.
