This 54 tooth extra large chainset for the Brompton is definitely for those who want a bit more speed out of their Brompton.

As standard on the 1 and 2 speed bikes but can also be fitted to any Brompton.

If you are fitting this to an existing Brompton then you will need to lengthen your chain a bit to cope with the extra teeth on the chainring.

3/32" gauge teeth so will work for 1, 2, 3, 5 and 6 speed Brompton bikes.

Includes BOTH cranks.
