The Brompton T Line Ceratech 12 Speed pushes the boundaries of what a folding bike can achieve. Built around a Grade 9 titanium frame, meticulously hand-welded and finished with a deep, rich Cerakote® protective coating, it weighs just 8.8kg making it the lightest Brompton ever created. The frame is not only featherlight but also incredibly strong and durable, giving you confident handling and effortless portability.
The innovative 12-speed drivetrain is a standout feature, combining Brompton’s clever 4-speed derailleur system with an integrated 3-speed hub gear. This set-up offers a broad range of gears to tackle steep hills, rapid flats, and everything in between, while still neatly folding down into Brompton’s iconic, ultra-compact package. Shifting is smooth and intuitive, designed specifically for the needs of city cyclists.
At the heart of the ride is the carbon fork and carbon crankset, which save weight and boost responsiveness, giving you a lively, connected feeling with every pedal stroke. The Schwalbe ONE tyres provide fast-rolling performance with Addix Race rubber and V-Guard puncture protection, ensuring you stay quick and protected on any surface.
Dual Pivot Caliper brakes deliver sharp, reliable stopping power, perfect for unpredictable city traffic. Meanwhile, Brompton’s clever folding mechanism, refined even further on the T Line, allows you to transition from riding to walking in just 20 seconds, its ideal for busy train platforms, offices or home storage.
Every detail has been obsessed over, from the magnetic pedal holder to the Superlight CNC aluminium pedals, ensuring this bike not only rides superbly but is a pleasure to live with every day.
Whether you're zipping across town for work, taking on weekend adventures or simply enjoying the freedom of two wheels, the T Line Ceratech 12 Speed offers the best urban ride possible.
