Description
Precision Suspension for Brompton’s Titanium Line
This Matumura-Kohki Scrowave suspension block is built specifically for Brompton’s P Line and T Line frames, replacing the stock rubber block with a compact stack of wave springs. The result is a firmer, more controlled rear end that keeps the bike feeling sharp under power while still taking the sting out of rough pavement.
Where the original bumper simply compresses, the Scrowave spring stack manages the load in stages. A firm tune with three stacked springs keeps the back of the bike planted for riders who like a very direct feel, while the soft configuration with two springs adds roughly 30% more give for a smoother, more forgiving ride.
Small Things – Big Difference
- Designed exclusively for Brompton P Line and T Line titanium bikes, matching the compact rear triangle and hardware layout.
- Scrowave wave-spring design offers a non-linear spring rate, providing support when you push hard and compliance over small bumps.
- Firm setup uses three stacked springs for minimal bob and a very connected ride feel.
- Soft setup uses two springs for about 30% more cushioning while still feeling precise and stable.
- Machined components turn a normally hidden part into a small piece of functional frame jewelry.
