2025 Brompton T Line

2025 Brompton T Line 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 performance. The carbon crankset gives greater power transfer. There are three T Line Models as per drivetrain deployed: One - 1 Speed. The lightest one. Perfect for an Energetic Rider who does not want to compromise on weight gains. Urban - 4 Speed. Just marginally heavier than the single speed one, but optimized for city performance, ensuring smooth gear transitions whether you're accelerating, cruising, or climbing hills. Explore - 12 speed. The lowest gear ever. ​The highest gear ever.​ And lots of small steps between, making this an even more comfortable ride for touring, exploring, commuting and beyond.​
