Genuine Brompton Gear Sprocket & Disc Set. If you use your Brompton as much as we do, then sooner or later the rear cogs will wear out and will need replacing. This is what you'll need.
Available in four variations to suit 1-speed, 2-speed, 3-speed, and 6-speed bikes, the cog sets all include a new plastic disc which prevents the chain falling between the cog and the spokes who misaligned and the necessary spacers and circlip.
If your Gear Sprockets needs replacing, then so does your chain. We recommend changing them at the same time to prevent slippage.
