Crafting a bamboo bicycle frame requires flexibility, precision, and the ability to adapt. Our modular dropout system is designed specifically for bamboo frame builders, ensuring your build can accommodate any drivetrain or braking system—both now and in the future.

Over the years, many builders have completed their frames only to realize they need disc brakes, a thru-axle, or a different groupset. With our modular system, you won’t face that problem. These interchangeable dropouts give you the freedom to future-proof your frame and create a truly versatile bamboo bike.
