Description
Small in size. Big on progression.

Purpose built to bridge the gap between 16 inch and full-size 20 inch setups, the Colony Cadet 18 inch Frame is everything a young shredder needs to step it up. Built with the same heat-treated, full chromoly construction as the big boys, this frame isn’t just scaled down — it’s fully dialed in.

Whether they’re hitting the skatepark, sessioning the streets, or just getting rowdy at the local, the Cadet’s progressive geometry keeps things tight, responsive, and confidence-inspiring. With a short 12.7” rear end, a snappy 75.2° head angle, and room out back for 2.4” rubber, this frame is as serious as the rider who's ready for it.

Colony didn’t cut corners either — you’re looking at a fully heat-treated integrated head tube, external DT gusset, tapered tubes, and dialed dropouts with built-in chain tensioners. Plus, removable brake mounts come included, so you can set it up however you like.

The Cadet 18” isn’t just a beginner frame. It’s a launch pad for the next generation.
