Brompton derailleur gear trigger / bell assembly complete

Brompton derailleur gear trigger / bell assembly complete

This 2 speed derailleur trigger was discontinued by Brompton in 2020

An alternative is this 2 speed Sturmey Archer shifter which will also need a new cable and derailleur spring

If you are fitting a new trigger housing, fit it at the same position and orientation as before, to avoid clashing with the front spokes when folded. You may of course choose another position, but:

• some adjustment of the handlebar nipple may be needed, or 
• the bell may end up exposed to damage when folded, or 
• the cable routing may not be satisfactory.
