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.
#BromptonCHPT3 - a global community
While mainstream cycling media and industry focus on traditional activities such as road racing, off-road riding, and, more recently, virtual riding, a global community has been growing under the radar. Folding bikes that can be stored in apartments, carried onto the metro and on buses, thus enabling urban meet-ups, back-alley racing, picnic adventures, and smile-inducing performance.
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.
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 lightweight 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 1.5kg / 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. *patent pending
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 inntertubes.
