Lighter, Stronger Hardware for Your P/T Line Hinge This Ti Parts Workshop rear hinge bolt replaces the stock steel hardware on Brompton P Line and T Line bikes with precision CNC-machined titanium. It’s a small change that cuts weight at the back of the bike and trades corrosion-prone steel for durable, weather-proof titanium. Designed specifically for the P/T Line’s thru-bolt rear hinge, it drops straight in where the original bolt lives and helps keep the rear triangle pivot feeling tight and precise over the long haul. Simple. Solid. Reliable. Direct replacement for the original rear hinge bolt on Brompton P Line and T Line frames. CNC-machined titanium construction resists rust and seizing in wet, gritty conditions. Roughly half the weight of the factory steel bolt, trimming grams where they’re hardest to lose. Maintains the clean, stock look while upgrading materials and long-term durability. Ideal finishing touch when refreshing a worn hinge or building a lightweight P/T Line.
