Brompton Derailleur Spring Set/Cable Stop for Gear Trigger (Pre-2017)

This is a derailleur spring set along with a cable stop designed for pre-2017 Brompton gear triggers. The Brompton derailleur on a two or six-speed Brompton makes the mechanism go back when you let go of the lever. It has a spring-loaded mechanism. Here are the details: Part code: QCTSPGTRIGSET, Part number: 9002795. It's suitable for 2 and 6-speed Bromptons.

Using this product is quite easy. First, make sure your Brompton is a pre - 2017 model and has 2 or 6 speeds. Then, install the derailleur spring set and cable stop according to the existing setup on your bike's gear trigger. When you're riding and using the gear lever, just release it and the derailleur will make the mechanism return. As for maintenance, regularly check the spring - loaded mechanism for any signs of wear or damage. If you notice that the spring doesn't seem to be working properly or if the cable stop is loose, it might be time for a replacement. Keep the parts clean by wiping them down occasionally to prevent dirt and debris from affecting their performance.
