The suspension is important on a small-wheeled bike. Bromptons is provided by a polyurethane block between the main and rear frames; lightweight and effective.
It smoothes out the lumps and bumps en route, while the natural damping of the material avoids excessive “bounce”.
Historically, Brompton has provided a choice of two different suspension blocks, a firm block, and a standard block. However, the design has been refined using new materials and a new compression profile which makes it more suitable for a much wider range of riders. As a result, we now only use one type of suspension block type with our bikes. The hardness of the new block is between the two old types of suspension.
