T Line Urban – 4 Speed Brompton

The all-new ultra-light titanium frame. Over 150 specially developed weight-saving components. Three years of obsessive material choices and rigorous testingEverything brand-new except the fold. Andrew Ritchie, founder, obsessed over that 40 years ago. Never bettered, just refined, it’s the original and still the best. The entirely re-engineered T Line titanium frame weighs 37% less than the original all-steel equivalent and is just as strong. At 7.95 kg in total, the T Line is comparable to a carbon road bike. Yet, it can be comfortably ridden by a 110kg rugby player. And withstand the punishing impact of the city.

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. The first bike in the world with a steel-armoured carbon seat post. We know because we invented it. Ordinary carbon seat posts are stiff, strong and lightweight, but they can’t stand up to the daily use of a Brompton. So, Brompton developed a new process to reinforce the limitations of carbon with 0.3mm steel armour. The result: a superlight extended seat post that can take the abrasion of the fold, 110kg load and all-weather riding (the T Line Brompton comes standard with the extended seatpost size). Faster to fold, easier to carry. They studied every interaction with the folded bike and improved it. New: self-aligning hinges, always set-to-go. A spring-loaded handlebar catch that effortlessly clicks. Larger diameter rolling wheels go with the flow—an easy-grab carbon saddle with an integrated nose handle. Nothing folds like this Brompton, not even other Bromptons. Brompton ride dynamics have always made owners smile, and now they’re elevated in every way. Carbon cranks and cast Ti bottom bracket shift your power for a faster ride. Naturally, shock-absorbing titanium smooths out the road. The one-piece carbon fork and wider carbon handlebars make it stiffer and even more responsive. This is a serious machine that’s seriously fun to ride

This bike is offered with the Mid Handlebar which is Brompton’s mid-height option giving the rider both a peppy yet comfortable ride, or the Low Handlebar giving the rider a sportier and speedier ride.
