Brompton derailleur spring set - pre-2017

The Brompton derailleur causes the mechanism to return when the lever is released  on a two or six speed Brompton.

This is the set along with dog-leg section and end stop - for pre-2017 derailleur / trigger systems (give us a ring or email us if you are not sure)

This should be added to the derailleur cable if you are after the complete set which was discontinued in 2017.

This video from Brompton shows how to correctly set up the 2/6 speed derailleur system.

      Hi! I'm thinking of making my old T5 into an M2L, will this derailleur be appropriate for the change considering the T5's short wheelbase? Answer:
      This is just the spring - To change from a T5 to a 2 speed you would need a wheel, cables - including spring, chain tensioner and trigger

      Hi the spring set on my 2017 M6 is definitely sticky, preventing movement of the chain shifter, any clues?? I think sticking near the cable entry Answer:
      Hi, thanks for the question. The main reason for this sticking is normally as it is dirty, cleaning is generally the best way to over come this.
