Brompton x CHPT3

Designed in collaboration with CHPT3, a brand established by ex-pro cyclist David Millar. A Brompton that a die-hard roadie would consider. Unique and custom built for CHPT3. Stylish, fast and guaranteed to stand out in any city.​

 

Beginnings

In 2015, David Millar met with Brompton CEO Will Butler-Adams. David expressed he rarely used a bike in the city, only for training and competing…​
Brompton x CHPT3 History

Testing

2016 saw the first prototype of the Brompton x CHPT3 come to life. David had been using a series of different Bromptons the previous year, working out through trial and error the spec required for the CHPT3 version.

Development

2017 saw the CHPT3 Brompton development continue. Production was scheduled for the end of the year. Titanium parts were being stockpiled at the new factory in London and Scwhalbe worked on producing the tan wall tyres that would match David’s racing bikes…

2018 Edition

2018 saw the first Brompton x CHPT3 special editions come off the factory line. Initially limited to 500 bikes, it soon became clear that demand would exceed supply.

2019 Edition

2019 saw the launch of the second version of the bike. An evolution rather than a revolution, the concept remained the same with the details refined and improved. The Brooks saddle and Ergon grips were replaced by industry leading British fabric. The Schwalbe ONE tyres were developed especially for the Brompton x CHPT3 2019. The tan-wall, with 35mm width, lowers rolling resistance and uses extremely cut-resistant high tech fibre - maintaining a high level of puncture resistance. The rear suspension block is race-tuned, offering a stiffer and more responsive ride which allows for improved handling. The fire red front tube is complimented by a textured black main frame as well as titanium forks and rear triangle.

2020 Edition

2020 sees the launch of the newly updated Brompton x CHPT3. What started out as a one-off experiment to merge some roadie ideas into a folding bike has morphed into a long-term relationship, with each team bringing new thinking to how the collaboration can evolve further in its third chapter.

2023 Edition

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.
