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.
