2024 Brompton T Line One

Brand-new everything. Except for the fold.

The all-new ultra-light titanium frame. Over 150 specially developed weight-saving components. Three years of obsessive material choices and rigorous testing. Everything brand-new except the fold. Andrew Ritchie, our founder, obsessed over that 40 years ago. Never bettered, just refined, it's the original and still the best.

Compact drivetrain, designed ground-up.

Nothing rides like it—the entirely new* drivetrain. Designed ground-up to sit inside the fold, to be light as possible and for optimal city performance. The carbon crankset gives greater power transfer. The 60-gram derailleur delivers smooth shifting in a small package. The new gear-ratio, tested from Amsterdam to San Francisco, perfected for city roads.



Front carrier block

Brompton bags can be quickly and easily attached to the front carrier block, which results in a secure and comfortable ride with an optimally balanced load.

Superlight carbon handlebars

With two options, low - for a sporty, more forward position or Mid for a natural, relaxed position.

Superlight carbon saddle

With oval carbon rails and carbon reinforced base, lightweight padding, integrated carry handle and light mount. Superlight pentaclip.

Schwalbe ONE black tyres

With its 349 x 35C size, it can provide a comfortable ride for riders of all sizes, and it is designed with safety in mind, with its reflective sidewall to help cyclists stay visible to others.

Superlight extended seatpost

The first bike in the world with a steel-armoured carbon seat post, for an inside leg up to 89cm / 35 inches.

Carbon fork

One piece carbon fork and steerer with magnetic pedal holder.
