Advance Rear Frame Locking Block
Take advantage of Brompton's innovative folding feature with our Advance Rear Frame Locking Block. This is a replacement locking block for P and T Line Brompton bikes, to increase rigidity and improve the bike's handling.

This Rear Frame Locking Block will hold your Brompton in place when folded to prevent it from unfolding unnecessarily when you're transporting, carrying, or storing it. Lift your Brompton easily when getting on trains, buses, and into a car while the block keeps it tucked away in its compact folded position.

The locking block is made from high-quality carbon fiber, and comes complete with a stainless steel bolt (instead of plastic), making it strong and durable. It is easy to install and adjust using just a 4mm hex key so you know your Brompton is always safe and secure in the folded position.

Our Advance Rear Frame Locking Block is an essential replacement part for your Brompton to make the most of the reliable folding feature when transporting and storing.
