Brompton 1/2 Speed Rear Wheel Titanium Cap Flange Nut Ti Parts Workshop Titan

This is a set of titanium rear wheel axle nuts designed for Brompton folding bikes and compatible aftermarket wheels like those from SMC. The set consists of three nuts—one standard nut and two cap nuts—machined from Ti-6AL-4V titanium alloy. They're designed to fit the outer dropouts on 1 or 2-speed rear wheel axles, replacing the standard steel hardware that comes with most Bromptons.

If weight reduction is a priority on your folding bike, titanium parts make a noticeable difference when you're carrying the bike regularly. This particular set weighs just 27.5 grams, making it a straightforward swap if you're already running a Brompton and want to shed a bit of mass without compromising strength. The CNC machining ensures the nuts sit properly and tighten securely, so there's no faffing about with fit or finish. They come in black, which matches the standard Brompton aesthetic.

The swap itself is straightforward—these are direct replacements for the factory nuts, so no modification or adjustment is needed. For anyone gradually upgrading a Brompton with lighter components, or simply looking to cut weight on a bike that gets carried as often as it's ridden, these titanium nuts are a practical choice. Postage is included as a tracked 48-hour delivery within the UK.
