Product Story

The first bike part Paul ever made was a quick-release seatbinder bolt, so it’s only fitting to have a QR seatpost collar in our lineup 30 years later.

Old school? New school? Cheap dropper? Super convenient? YES!

These are lovingly machined out of USA sourced aluminum and stainless steel. They are currently available in 30.0mm, 31.8mm, 33.1 and 35.0mm. Available in polished, purple, black, silver, and with orange accents.

Should we bring back #FixtureFriday ? Before you can make all the parts, you have to make all the fixtures, and these aren’t something you can buy off a shelf! All of our production and assembly fixtures are one-offs made by Paul or Patrick or Jacob in the manual machine shop (although Jacob just made our first ever 3D printed fixtures, but that’s a story for a different Friday 😉).
This fixture is for pressing the little sealed cartridge-bearings into our Canti and Love levers. Once mounted in an arbor press, a little magnet holds the bearing until you press-fit it into the lever blade with a pull on the arbor press. In theory these bearings could be replaced down the line, but we haven’t had to do it yet. Thank you for attending our Ted Talk, happy Friday! ✌️

Boxcar Stems are available in 35 through 110mm length, and are machined right here in sunny Chico California to the tightest tolerances, using the highest grade 2024 American-milled aerospace aluminum available. Sure, you might see us goofing off and getting weird at bike events, but when we get back to work in the machine shop, we take our work VERY serious!
