Brompton P Line 12-speed 2026 Specifications
The Brompton P Line has been updated for 2026 with features that align it more closely with Brompton's top-of-the range T Line. The P Line bridges the gap between the all-steel C Line and the titanium & carbon T Line: The steel main frame, titanium rear frame, carbon fork, new aluminum stem, and wider handlebars make a light, great handling folding bike.
