Four years ago, one of Britain’s most successful and influential cyclists David Millar, the man behind the CHPT3 brand, met with Brompton CEO Will Butler-Adams. David expressed that he rarely used a bike in the city, only for training and competing, so the conversation turned to what would be the best Brompton for a die-hard ‘roadie’, not a pastiche but a bike that was lightweight, stripped-down, dynamic to ride but useful day to day. That conversation kick started the collaboration and was the moment the idea for the Brompton X CHPT3 was forged.
