Full Product Description




The Iconic Moulton Spaceframe – Reimagined in Titanium
The ALEX MOULTON GT MK3 is a legend – a spaceframe Grand Tourer with a ride quality that’s earned it a cult following worldwide. But the original is built from lugged stainless steel, making it heavy (complete bikes often exceed 10kg), and the frame alone tips over 3.5kg.
We changed that.
The HEXATI Titanium AM GT MK3 frameset is crafted entirely from aerospace‑grade titanium alloy – main frame, rear triangle, fork, and head tube. No steel. No compromise. Just pure, lightweight titanium that preserves the original’s legendary stiffness while cutting frame weight to an incredible 2.89kg.
Complete bike weight? Just 9kg – a massive reduction from the original.
✨ Why Titanium?
- Shiny & Never Rusts – That mirror‑like titanium finish stays beautiful forever. No paint chips, no corrosion, no worries.
- Same Stiffness, Less Weight – Titanium delivers the same structural rigidity as the original stainless spaceframe, but at a fraction of the weight.
- Compliant Ride – Titanium’s natural vibration damping smooths out rough roads without sacrificing pedaling efficiency.
- Built to Last – Corrosion‑proof and fatigue‑resistant. This frame will outlast you.
⚙️ Rohloff TS EX Hub Compatible
This frameset is specifically designed to work with the Rohloff SPEEDHUB 500/14 TS EX – the gold standard of internal gear hubs.
- Horizontal Dropouts – The TS EX version is designed for frames with horizontal dropout slots, allowing the hub to be mounted with axle nuts.
- Two Installation Options:
- Use the horizontal dropouts for direct chain tension adjustment
- Or install a torque arm + chain tensioner for an alternative setup
- Perfect for 17″ wheels – The TS EX is ideal for smaller wheel formats like the Moulton’s 17″ (ETRTO 369mm) rims.
🛠️ Build Your Own – DIY Friendly
Many欧美 customers love the AM GT MK3, but the factory‑built versions come with expensive shipping costs and non‑electric drivetrains that don’t suit everyone. Now you can buy just the frameset and build it your way:
- Choose your own groupset (mechanical, electronic, or internal gear)
- Select your preferred wheels and tires
- Customize the cockpit to your fit
- Save on shipping by ordering the frame only
The frameset includes: titanium main frame, titanium rear triangle, titanium fork, titanium head tube, and all necessary hardware for assembly.
