After a meticulous two-year development journey encompassing 578 design iterations and hundreds of prototypes, we are proud to announce the commencement of pre-orders for the Titanium Alex Moulton GT MK3. This is not merely a replica; it is a complete re-imagining of the classic, engineered from the ground up with the anatomical and performance needs of Asian cyclists in mind.
Constructed entirely from aerospace-grade titanium alloy, the frame achieves a remarkable balance of featherlight weight—under 9kg—and exceptional strength, with a tensile strength of 900MPa. The bike combines the use of ultra-fine seamless titanium tubing with 3D-printed titanium components at critical junctions like the BB bracket, and the wishbone stem, each unit painstakingly hand-built and hand-welded over 25-70 hours by master artisans.
A Paradigm Shift in Geometry and Compatibility
While honoring the soul of the original, we have implemented a series of revolutionary updates to enhance fit, performance, and modern compatibility:
- Universal Wheelset & Optimized Frame: We replaced the rare 17-inch wheels by re-engineering the frame with topology optimization. After 37 CAD simulations, we achieved compatibility with versatile 406 (20-inch) wheels while retaining the option for the original 369mm setup. An asymmetric reinforcement design increased frame rigidity by 18%.
- Lowered Bottom Bracket (BB Drop): The original 328mm BB height was aggressively lowered to 280mm, creating a significantly lower center of gravity. This “golden ratio” upgrade enhances stability and improves pedaling efficiency by 19%.
- Modernized Head Tube: We transitioned from the obsolete 1-inch standard to a modern 28.6mm head tube, ensuring broad compatibility with contemporary stems and handlebars.
- 3D-Printed Titanium Wishbone: The new wishbone stem, crafted via additive manufacturing, sheds 300g while boosting lateral stiffness by 15%.
- Refined Wheelbase & Chainstays: The wheelbase has been shortened from 1120-1150mm to a nimbler 1050mm. The rear chainstays were updated to a modern 280mm, shortened by 12.5% yet achieving a 27% increase in longitudinal rigidity.
The Culmination of a Two-Year Odyssey
The GT MK3 is the fruit of over 700 days of relentless refinement. It represents a paradigm revolution in suspended bike handling, transforming a classic into a contemporary performance machine. Every millimeter of adjustment was validated through thousands of dynamic simulation tests, ensuring that each change contributed to a superior, more responsive, and perfectly balanced ride.
“We didn’t just change sizes; we re-engineered a legend,” said our Lead Engineer. “From the 3D-printed titanium parts to the 14% lower bottom bracket, every detail was scrutinized to create a bike that offers an intuitive and exhilarating connection for the Asian cyclist, without compromising the legendary Moulton comfort.”
