This was my first Tree Splined Lite Sprocket, from 2009. Sam was selling a few copper-plated sprockets and I scooped one up, curious as to how a BMX drivetrain would feel on a fixed gear. Since then, it’s the only sprocket I’ve ridden, both on my BMX and FGFS rigs. Recently, I’ve tried out some other brands, which I’ll be reviewing shortly but I just wanted to say hats off to TREE BICYCLE CO for innovating the game and designing the first 48 splined sprockets. They’ve been making these for over 6 years now.
