Brompton suspension block - excluding fittings

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

There used to be two levels of resistance available, to suit body weight and riding style.

Since 2017/2018 there is a "one size fits all'' suspension block (this one)

Compatibility:

This suspension block is for 1-speed, 2-speed, 3-speed and 6-speed C Line (and older) and C Line Electric bikes only

This suspension block will not fir the following Brompton models:

  • P Line
  • T Line
  • G Line
  • C Line Electric 4-speed and 12-speed

as the above models use an advance rear frame with a different shape suspension block

We made this short video (below) on how to install the Brompton suspension block - and a bit of information on the (previous) different types
