Over the years, stem technology has changed up pretty drastically. They’ve gone from these blocks of alloy steel that had 6 (sometimes 8!) bolts in them to keep your bars and fork connected while holding that headset in place all the way down to these crazy CNC machined to the max stems with one bolt holding it all together. It just goes to show how much innovation has come to a part like a stem over BMX’s fairly short history. A few weeks back, the guys at Proper Bike Co. let me in on a wedge based stem system that’s been in the works for a couple a years now. After being put on the back burner for a while, they’ve finally designed something they’re totally happy with and are getting the test results they want in order to really give it that Proper stamp of approval. All though the stem won’t be out for a few months, we figured it would be cool to give you guys a sneak peek at both versions of this stem and find out what really went into the making of it. This is what Jamie over a Proper had to say… Let’s take a closer look!
