Lighter Saddle Clamp for Your Brompton This Ti Parts Workshop Pentaclip bolt is a direct titanium replacement for the stock saddle clamp bolt on Brompton P Line and T Line bikes. It keeps the familiar Pentaclip adjustment you already know while quietly trimming grams from one of the heaviest small parts on the bike. CNC-machined from Ti-6Al-4V titanium, it resists rust, handles everyday riding loads with ease, and is available in multiple finishes to match or contrast your build. A small upgrade, but one you see and feel every time you adjust your saddle or lift the bike. Small Things – Big Difference Designed specifically for the Brompton P Line and T Line Pentaclip saddle clamp system. Direct swap for the original steel bolt, keeping standard Pentaclip saddle angle and fore–aft adjustment. CNC-machined Ti-6Al-4V titanium for high strength, low weight, and excellent corrosion resistance. Shaves several grams compared to the stock bolt, one of the easiest weight savings on a P/T Line build. Offered in anodized finishes (typically black, silver, and gold) to blend in or add a subtle highlight. Quick, straightforward installation for anyone already comfortable working with the Pentaclip clamp.
