Matumura Kohki Scrowave Suspension Spring for P / T Line - Firm - Gold

Upgrade Your Brompton's Ride with Precision Japanese Engineering

The Matumura Kohki Scrowave Suspension Spring is a premium replacement for the standard Brompton rear suspension block, specifically designed for Brompton P Line and T Line folding bikes. Manufactured in Japan using innovative Scrowave wave spring technology, this Firm version delivers a noticeably more responsive, controlled ride while maintaining excellent small-bump compliance.

Unlike conventional rubber suspension blocks that compress at a constant rate, the Scrowave suspension uses a stack of specially engineered wave springs with a progressive, non-linear spring characteristic. This allows the suspension to remain supple over small road imperfections while providing increased support under heavier loads and harder pedalling, improving both comfort and efficiency.

The Firm model features a triple-wave spring configuration, making it ideal for riders who prefer a sportier feel, regularly carry luggage, or simply want to minimise unwanted suspension movement during hard acceleration and climbing. The result is a more connected ride with improved power transfer while still taking the sting out of rough roads.

Designed exclusively for the titanium rear triangle found on the Brompton P Line and T Line, the Scrowave Suspension Spring is supplied as a direct replacement and is an excellent upgrade for riders seeking enhanced performance without compromising Brompton's renowned folding capability.

- Premium Scrowave wave spring suspension system
