Curve Belgie Spirit Titanium


Curve Spirit Complete Ultegra Primary

Endurance Geometry

Ride all day comfortably and confidently – whether crossing the Nullarbor Plain or exploring the Alpine regions. The Belgie Spirit geometry is less aggressive and more stable so you can ride longer than ever. Flat-mount disc braking means you can ride on the hottest and wettest days of the year without compromise. Compound Curve seat stays for small bump relief combined with clearance for up to 32c tyres allows for a smoother ride on rough roads.

Hand Built with a Lifetime Warranty

All frames are impeccably hand built in the Peoples Rep. of China and we are proud of our production partner. So you can ride it hard and fast, titanium must be machined and welded with care and precision. Our frame builders are masters in the art of continuous seam welding and we utilise a meticulous machining process that is accurate to the micrometer.

We are so confident in the quality of our titanium frames that we offer a Lifetime frame warranty.

Ti is Fly

At the core of each frame is a 3Al – 2.5V Grade 9 Aerospace Grade titanium tube-set. This grade is optimal for the manufacture of bicycle frames and has been chosen for its balance of stiffness, compliance and durability. Every tube is specifically optimised across each size and model.
