FOLDING RUGGED FRAME (MOUNTAIN BIKE OR GRAVEL BIKE)

 

If you’re building a bike to go off the beaten path, you’ll want to start with something light, yet rugged. Unlike other folding bike frames, this light (5.5 lb) double-butted aluminum hardtail frame has passed the ISO 4210 destruction test suite for mountain bikes. And yet, unlike other MTBs, a bike built on the CHANGE 833 frame can travel everywhere in your car trunk, free from weather, road grit, and curious hands. After your day on the mountain, you can enjoy your dinner and trail stories in peace, knowing that your amazing ride is safely tucked away from view in your trunk.
