Machined in California from aerospace aluminum, this stiff box-shaped stem resists torsional flex across six lengths

The Paul Components Boxcar Stem is machined from 2024 American aerospace aluminum in Chico, California, a grade chosen for its strength-to-weight ratio rather than cost. Where most stems leave steering feel up to bar choice and fit, the Boxcar's box-section geometry keeps input direct whether it's set up short and steep on a mountain bike or long and low on a road build. Stainless steel T25 Torx faceplate hardware rounds out a stem built to be installed once and forgotten.
