More info

The new Brompton "Spider" crankset was introduced on new Brompton bicycles at the beginning of 2013.

One of the many benefits of the new crankset is that you can change the gearing without having to change the complete crank set - you can change the chain ring (held on with 5 bolts) and the chain, to alter your Brompton bicycles gearing. 

This is a replacement 54 tooth chain ring complete with guard.

It can be used to replace the 44,  50 or 54 teeth chain rings on a "spider" type crank.

Changing from the standard 50 tooth 3 speed to 54 tooth will increase your gearing by approx. 10% making getting up hills slightly tougher but giving a higher top speed on the flat.

A standard 1 or 2 speed Brompton comes with this 54 tooth front chain ring

    Do I need a new chain to go with this or will the old one have enough extra length to accommodate? Answer:
    You would need a longer chain. If you currently have a 50T setup you would need 2 extra links and if you have a 46T setup you would need 4 extra links.
