The 4th Edition
Turning a new page in the Brompton and CHPT3 story, the latest collaboration brings a fresh dynamic to a proven partnership. One founded on fun, practicality, and high performance.
Drawing on our previous three collaborations with David Millar of CHPT3, we turn to page 4, and the horizon broadens. A bike that originated as a city commuter and became a daily workhorse for David, a former pro-cyclist, is now embraced by a community who see beyond simply departing from point A and arriving at point B.
To own a Brompton x CHPT3 is to belong to a community of like-minded riders from Indonesia to Indianapolis, a community that is powered by new members like you.
Made for speed
Handbuilt titanium and steel frame. All the practicality of a Brompton in a lightweight and performance oriented form.
More than 1.5kg lighter than the original bike.
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.
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.
