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.
