Brompton Brompton x CHPT3 4th Edition

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 light weight inner tubes, which means you can focus on avoiding the shortest route to reach your destination.
