Reverse Components HG Single-Speed Conversion Kit - 13T (Silver)

The Reverse Components single-speed conversion kit allows you to convert your conventional hub with a Shimano-HG freewheel body into a clean, dependable single-speed drivetrain. Thanks to the seven included spacers, the cog can be precisely positioned on the freehub body to guarantee a straight, perfectly aligned chainline.

The Reverse single-speed cog features an extra-wide base flange of 7 mm, which distributes power transmission gently across the freehub body. While standard cogs feature a narrow 2.8 mm flange that can easily bite into and permanently damage softer aluminum freehubs, the 7 mm width drastically reduces this risk. Additional individual cog sizes (13T-18T and 20T) are available separately.

Key Features

• Freehub Protection: Extra-wide 7 mm base flange prevents the cog from chewing into softer aluminum Shimano HG freehub splines.


• Perfect Chainline Tuning: Includes 7 different spacers for flexible lateral positioning and optimal drivetrain alignment.


• Broad Chain Compatibility: Engineered to work smoothly with 1-to-11 speed chains, including 1/8" and 3/32" widths.


• Durable Construction: Combines a tough steel cog and matching lock ring with lightweight aluminum spacers.
