Are you thinking about picking up a new BMX stem, but you aren’t really sure what all of those measurements really mean? Here’s a video Brant Moore put together going in-depth on the different measurements like reach, rise and stack height, along with a measurement you might not have heard of called extension. Along with that, Brant discusses some of the different features on stems like CNC machining for weight savings and cleaner looks, a wider stem for increased strength, the 1″ OD size that brands like Wethepeople, BSD and Cult have been trying out, the grooves that Flybikes offer on their stems, knurling, etc. Brant also covers solid and hollow bolts, and a few other things. This will definitely help if you are curious what you need to know when it comes to stem geometry and features. Hit play and take it all in!
“BMX stem geometry appears quite simple at first glance, and for all practical applications of stem geometry, it is as simple as it seems.
However, there is more than meets the eye and a lot to talk about in regards to BMX stems and their geometry.
Hopefully this video can help you make an educated decision the next time you’re in the market for a new stem!” – Brant Moore
