Reverse Expert HG Single Speed Kit converts a standard HG-compatible cassette freehub into a clean, reliable single speed setup designed for aggressive riding and full-suspension bikes, where chain control matters. The kit’s refined tooth profile and integrated sprocket guide system help keep the chain engaged and stable under compression, rough landings, and high-torque efforts—without relying on a traditional multi-speed cassette.
HG freehub single speed conversion - Fits most Shimano/SRAM HG-style freehub bodies to simplify a wheel’s drivetrain to one cog
Refined tooth profile - Promotes more secure chain engagement than typical single speed cogs for fewer drop-chain moments in rough terrain
CNC aluminum sprocket guides - “Sandwiches” the chain at the rear cog for added stability, functioning like a compact rear chain guide
Mud-shedding guide pattern - Machined reliefs help clear dirt and debris to maintain engagement across wet or dusty conditions
Complete kit - Includes single speed cog, alloy lockring, spacer, and two sprocket guides for a purpose-built HG single speed setup
