Brompton Brompton x CHPT3 4th Edition

A minimalist Brompton P Line, packed with high-performance details. We selected proven performance modifications such as titanium forks and rear triangle, assembled for speed without loss of comfort. The gearing is chosen to cover all bases, from quick sprints and sustained speed to steep climbs. All contact points between you and the bike, and the bike and the road deliver lightness, performance and comfort. We’ve even sourced light weight inner tubes, which means you can focus on avoiding the shortest route to reach your destination.

Made for Speed

Handbuilt titanium and steel frame. All the practicality of a Brompton in a lightweight and performance oriented form. More than 3.3lbs lighter than the original bike.

fi'zi:k Terra Argo X5 Saddle

We chose this gravel-specific saddle for the superb vibration absorption, and the short nose. This gives you a stable, planted position. You can shift further forward too – the ergonomic design minimises pressure on any sensitive parts. Cleverly thought-out drainage channels make it brilliant for wet-weather riding.

Superlight, compact gearing system

The Brompton 4-speed system* for rapid urban acceleration and nimble climbing ability. With a 60-gram derailleur, meticulously engineered to fit inside the narrow fold.

A fast and light wheelset

Designed and tested to stand up to daily use in the city, in all weathers. On superb tan-walled Schwalbe One tyres for optimal grip and maximum style. With weight-saving Tubilito inner tubes.

Brompton x CHPT3 Frame Pouch Bag

Your CHPT3 comes with a limited-edition Frame Pouch Bag. It’s inspired by how the community use their Brompton x CHPT3 bikes - moving fast around the city, racing, heading out on long weekend rides. It’s perfectly sized for a spare tube and tools. Just like the bike, it’s minimalist, practical and brilliantly durable. In abrasion resistant Hypalon fabric with a welded, waterproof construction.
