A High Quality BMX Stem
I prefer front-load BMX stems, and this one is pretty nice. The Colony Official is fully machined, uses better metal, and has a good looking design. In my opinion. Mine have yet to slip or have any problems.
Kind of expensive for a single bike part.
I gave the Colony Official Stem a 5 star rating. It Is one of my favorite bike parts that I own. Like it's design, function and looks.
Advice: To get a good clamp on your fork and bars, so that they don't slip. Clean all grease and dirt from both your handle bar and fork surfaces. Only grease the bolt threads. Use a long handle Allen wrench. So that you can get enough leverage to torque it down. Installed mine that way, and have yet to slip. I used Teflon grease
