A distinctive looking stem for the discerning rider, the Paul Boxcar Stem is strong, stiff and relatively light, and we can’t believe how good it looks! Available in sleek black or seductive silver, the Boxcar Stem will enhance your ride with its boxy wondrousness. According to Paul, the Boxcar Stem is 25% stiffer than the competition and has been shown to offer the optimum combination of strength, stiffness and weight based on extensive real world and machine testing.

The Boxcar Stem has stainless steel T25 torx bolts for securing the stem to the steerer and the handlebars to the stem. T25 torx bolts are more secure against theft or vandalism than standard hex bolts (as they are less ubiquitous) and are also less likely to be rounded out, making them a great choice in this context. If you’re a fan of the industrial chic look and are after a sub-100mm length stem, the Paul Boxcar stem could be a great option for you.
