Brompton suspension block - complete with fixings

This is the complete Brompton suspension block assembly complete with bolt and fittings

Until 2017 there were two levels - standard and firm - which one was used was based upon rider weight and prefered riding style. Now there is only one.

Suspension is important on small wheeled bikes such as the Brompton.

The suspension on a Brompton is provided by a polyurethane block mounted between the main and rear frames.

Lightweight and effective, it smooths out the lumps and bumps and helps to avoid excessive bounce.

Tip: To stop the suspension block creaking/squeaking when you ride - put a good quality grease on the bolt which runs through the middle

    Suspension Block. In your award winning video there is a degree of movement once the rear frame is locked in the main frame. I’ve noticed a rattle occasionally on rough road surfaces and wonder if the block needs replacing? How do you tell? The Brompton is 2019 and I am a sylph like 90kgs. Best regards Answer:
    Thanks for watching! A rattle is unlikely to mean the suspension block needs replacing. We would generally replace it if it does not return to the normal shape when not being riden
