T-Line

5.9 kg — Internal Cable Routing5.9KG

The lightest Brompton T-Line we've built while keeping all functionality and, in fact, extending the gear range from standard 11-18T to 11-28T. The client from Singapore also wanted his Brompton T-Line to be custom cerakoted to match his Range Rover - done! And we've also added custom cable ports on the stem and frame to allow for the fully internal cable routing - our signature mod 🤟

CHPT3

The client wanted to upgrade his stock Brompton x CHPT3 to reduce weight as much as possible while keeping it cool hence aero Garbaruk chainring. The weight was reduced to 7.55 kg while extending the gear range to 11-28T. A seriously fast bike that the client uses to overtake road cyclists in Richmond Park, London :)

T-Line

My personal T-Line — 5.97 kg5.97 KG

As featured on GCN Tech (video below)! My personal Brompton T-Line build. Every part selected to push total weight under 6 kg while maintaining the daily rideability. I decided to keep the titanium frame in raw and add some colour with the purple/blue Extralite and Cane Creek components. Custom internal cable routing added for the clean looks.

T-Line Neon Green

Custom Cerakote — Neon Green

The client wanted his Brompton T-Line to stand out while keeping it clean. So we went with this neon green cerakote colour and all black components for this contrasting bright look. All parts were selected to keep the weight below 6 kg.
