A replacement set with left and right hand crank, including chainring and chainguard, as found on post 2013 Brompton Bikes.
A standard 1 or 2-speed Brompton comes with a 54 tooth front chain ring.
A standard 3 or 6-speed Brompton comes with a 50 tooth front chain ring - changing to 54 teeth will increase the gearing by approx 8%.
The Bottom bracket is NOT included - If upgrading from the old fixed crankset then you will also need to change the bottom bracket (the old one was ISO standard and the new one is JIS standard).
