Paul Components Boxcar Stem

The Boxcar stem listed here is specifically designed for 22.2mm handlebars. Please double-check your handlebar diameter before purchasing, as it will not fit standard 31.8mm or 35mm bars.

The six-bolt pattern is designed to distribute clamping force more evenly across the handlebar surface. When installing, tighten the bolts in an 'X' or cross-pattern to ensure the faceplate seats evenly and maintains proper tension.

Yes. The Boxcar is CNC machined from 2024 aerospace aluminum and features a rounded box geometry specifically engineered for high stiffness and fatigue resistance, making it more than capable of handling rigorous trail use.

This stem has a 36mm stack height. This measurement is important because it dictates how much steerer tube length you need; ensure your fork's steerer tube is long enough to accommodate this height plus any headset spacers you plan to use.

A 0mm rise means the stem sits perfectly flat relative to the steerer tube. This provides a neutral, aggressive riding position that is ideal for riders looking to keep their front end low and handling responsive.
