Smoother Ride for Brompton’s Advance Rear Triangle
The Brompton Advance Suspension Block + Fittings sits between the main frame and the Advance rear triangle, taking the sting out of rough pavement on small 16 inch wheels. It replaces a worn original block or completes an Advance rear frame conversion so the back of the bike feels controlled instead of harsh or bouncy.
Supplied as a complete kit with block and hardware, it is built for bikes that use the newer Advance / Mk6 rear triangle. Once fitted, it quietly does its job on every ride, adding comfort and stability without adding complexity or weight you do not need.
Design That Works
- Purpose built for Brompton frames with the Advance / Mk6 rear triangle, matching the updated rear end geometry.
- Compact elastomer block smooths out road vibration and sharp bumps, improving comfort and rear wheel traction.
- Helps control rear frame movement so the bike feels planted when you are climbing, sprinting, or cornering.
- Complete kit with block and fittings so you have what you need for a straightforward replacement or upgrade.
- Simple install with a 5 mm hex key, an easy job when you are already servicing the rear frame or drivetrain.
