HEXATI Titanium Thru-Axle Rear Triangle for Brompton Bicycle

Titanium Thru-Axle Rear Triangle V2.0

This upgraded 142mm × 12mm titanium thru-axle rear triangle is designed with a symmetric front-fork-style specification, eliminating the need for conversion adapters for a cleaner and more integrated setup.

Constructed using aerospace-grade titanium tubing, 3D-printed structural components, and precision TIG welding, the rear triangle weighs only 576g while maintaining exceptional strength and durability. Compatible with 355 tires, it improves rear wheel contact area and helps reduce power loss for more efficient riding performance.

Thanks to the corrosion resistance and fatigue durability of titanium, the structure remains stable and deformation-free even under frequent folding and aggressive riding conditions, delivering more direct power transfer and long-term reliability.
