Paul Components Boxcar Stem

The rounded box shape is engineered specifically to increase torsional rigidity. This means the stem resists twisting forces better than traditional cylindrical designs, providing more precise handling and steering feedback.

Paul Components uses T25 Torx hardware because it offers a more secure interface for the tool, which significantly reduces the risk of stripping the bolt heads during installation or adjustment.

Yes, this stem is designed for a standard 1-1/8 inch (28.6mm) steerer tube, which is the most common size for modern mountain bikes.

A 0-degree angle provides a neutral rise, making it a versatile choice for riders who want a balanced position that isn't overly aggressive or too upright. It is ideal for trail riding where you want to maintain a comfortable but responsive cockpit.

Because it is CNC machined from high-quality 2024 aircraft alloy, it is exceptionally durable and requires very little maintenance. Simply ensure the bolts are torqued to the manufacturer's specifications and check them periodically as you would with any other cockpit component.
