Brompton Full Overhaul

Brompton Full Overhaul

Reviving the Ride: Overhauling a 15-Year-Old Brompton for a New Adventure

In the fast-paced world of cycling, where innovation and technology are constantly pushing boundaries, there's something timeless about a well-loved bike that has stood the test of time. One such iconic model is the Brompton folding bike, a compact and versatile companion for urban commuters. As the years go by, these trusty steeds may start to show signs of wear and tear. In this blog post, we'll explore the process of overhauling a 15-year-old Brompton, transforming it from a relic of the past into a sleek, efficient, and reliable ride for the future.

Assessment and Planning

The first step in reviving any vintage Brompton bike is a thorough assessment. We took a close look at the frame, wheels, drivetrain, and all components to identify areas that need attention. Rust, worn-out bearings, and outdated components are common issues in older Bromptons. Once we've identified the areas requiring attention, it's time to plan the overhaul.

Considering the goals for the overhaul, are we aiming for a complete restoration to maintain the Brompton's original charm, or does the owner want to modernize it with upgraded components for enhanced performance? This decision will guide the parts and accessories needed for the project.

Full Strip-Down and Deep Cleaning

Rather than a traditional frame inspection, opt for a full strip-down of the Brompton. Disassemble every part of the bike, including the drivetrain, brakes, and folding mechanisms. This allows for a meticulous examination of each component and ensures a thorough cleaning process.

The disassembled parts are then put through a deep cleaning process, especially for components like the suspension block and the rims becomes crucial. Professional cleaning removes accumulated grime, grease, and rust, revealing the true condition of each component. It's a crucial step for achieving optimal performance in the subsequent stages of the overhaul.

Upgrading Components

With the Brompton now in a state of disassembly, it's the perfect time to upgrade components. We replaced worn-out or outdated parts, focusing on the drivetrain, shifter, brakes, and wheels. Modernizing these elements can significantly enhance the Brompton's performance and overall ride quality.

Elevate your riding experience with comfort upgrades. Replace the old grips and shifter with a more ergonomic design that suit your riding style. Ergonomic grips can reduce hand fatigue during extended rides, making your revitalized Brompton not only efficient but also comfortable.

We installed a new shifter and derailleur set for smoother shifting and increased efficiency. We also upgraded the brake pads and cables for improved stopping power, ensuring a safer ride.

The suspension block is a key component that contributes to the overall comfort of the ride, absorbing shocks and vibrations. In a 15-year-old Brompton, the original suspension block might have lost some of its resilience. Consider upgrading to a modern suspension block that offers improved damping characteristics, enhancing the Brompton's ability to absorb bumps and irregularities on the road.

Modern suspension blocks often feature adjustable settings, allowing riders to fine-tune the level of firmness or softness according to personal preferences and riding conditions. This upgrade not only improves comfort but also brings the suspension system up to contemporary standards.

Folding Mechanism and Hinges

The Brompton's foldable design is a hallmark feature, making it a favourite for urban commuters. With the Brompton in pieces, pay special attention to the folding mechanism and hinges. Disassemble, clean, and lubricate these components thoroughly to ensure seamless operation. Inspect folding joints for any signs of wear and replace worn-out parts. If durability is a priority, consider upgrading to stainless steel or titanium components. This attention to detail ensures not only smooth folding and unfolding but also a longer lifespan for these critical parts.

Finishing Touches

As we near completion, we focus on the finer details. Replace worn-out cables, fine-tune the Brompton's fit to your preference. A fresh set of cables, a new chain, or stylish options can give your Brompton a modern and personalized appearance.


Overhauling a 15-year-old Brompton is a journey of rediscovery and transformation. With a comprehensive strip-down, deep cleaning, and modern upgrades, you can give your trusty companion a new lease on life. Embrace the nostalgia of the past while enjoying the performance and efficiency of the present – your revitalized Brompton is ready for many more years of urban adventures.
