Reverse Microspline Single Speed Kit converts a Shimano Micro Spline freehub wheel into a clean, reliable single speed setup—ideal for riders who want fewer moving parts, lower maintenance, and a straightforward drivetrain feel on trail or dirt-jump builds.
Precision CNC machined and finished in black anodizing, this kit is built to deliver a secure, purpose-made interface for running one gear on a Micro Spline driver. For full-suspension frames where chain growth can complicate single speed conversions, it pairs especially well with the Reverse Colab Chain Tensioner (sold separately) for a stable, hassle-free setup.
