The Double Six single speed kit is our premium level kit featuring a 7mm wide spline base Shimano HG fit cog to ensure power transfer doesn’t score or destroy alloy freehub bodies. Our tapered spacers are designed to offer increased lateral support for the cog under load.

• Single Speed adaptor kit for 8/9/10/11 speed cassette hubs.
• Pair of CNC machined aluminium spacers that look much sweeter than a bunch of washers to space out a 'Deep-tooth' single sprocket.
• CNC Cr-Mo cogs have wide 7mm base to avoid ripping into the cassette body.
• Built-in offset optimises chainline.
• Supplied with 16T 5/64" cog* and lockring.
