Paul Components was founded in 1989 in a renovated garage in Chico, California, a former Texaco Oil distribution facility dating back to 1926, and has been meticulously manufacturing bicycle components in that garage ever sincE Paul believes that great products should be based on simple ideas, easy maintenance, and a high level of functionality.

The Boxcar stem is a perfect combination of rigidity, strength, and lightness that Paul has been working hard to develop over the years.

Available in 35, 50, 70, and 90 mm with +/- 0° angles, or +/- 15° angles for 70 and 90 mm.

The 35mm size is a much-needed addition for many mountain bikers, as it is the answer to the longer top tube and shorter stem style of today's all-mountain bikes.

All screws are high-strength stainless steel with T25 Torx heads. The Torx head prevents the problem often seen with aluminum stems of over-tightening the faceplate and cracking it, and at the same time, this size is the same as many disc rotor bolts.

Made in U.S.A. Chico, California
