AIR Belgie

The AIR Belgie combines the stiffness of carbon and comfort of titanium to create a new standard for high end road bikes in the Curve range.

The backbone of each AIR Belgie frameset is a 3Al - 2.5V Grade 9 aerospace grade titanium tube set, optimal for bicycle frames. Our tubeset is carefully chosen to balance of stiffness, compliance, and durability. Titanium absorbs road noise without compromising on performance meaning you'll finish longer rides without feeling battered.

The hybrid carbon-titanium construction is not purely for aesthetics. The phenomenally strong double-lap carbon-titanium bond at the 3D printed power-pyramid bottom bracket assembly, mean improved stiffness and and a leap forward in power transfer.

All AIR Belgie frames are bonded and finished by Curve in Melbourne, Australia. AIR artwork, painting and cosmetic finishing are completed by hand within Curve’s new paint facility using high-end automotive products. This is part of Curve's mission to establish key elements of our manufacturing process in Australia where we can control, develop and refine new processes in-house.

Fabrication of the handmade titanium frame, carbon tubes and 3D-printed titanium elements remains with our trusted and established partners in China.

The clean minimal aesthetic of hidden hoses and cables is perfectly suited to titanium bikes and it is finally available on select Curve models through our partnership with Columbus.

The cleverly engineered Columbus Trittico cockpit system, allows fully internal routing through our sleek tapered headtube. It's the most elegant hidden cable and hose execution we have seen on a metal bike without significant customisation.

Trittico is the new family of carbon fiber bicycle cockpit components designed by Columbus. All Trittico components are characterized by state-of-the-art performance, weight, reliability and a stunning yet minimalist aesthetic, perfectly suited to finish a clean internally routed bike.

Our 3D-printed titanium frame components include sub-millimeter bond-gap control features. While such fine details are invisible on our finished frames, they result in class leading bond strengths.

Selective use of 3D printing has been used throughout the AIR Belgie. The 3D-printed SRAM UDH-compatible dropouts result in an elegant silhouette while shave grams. A 3D-printed titanium front derailleur clamp turns flimsy front shifting into a precise and definite movement. A 3D-printed guide routes the rear brake hose through neatly the bottom bracket.

An optional finishing touch is Curve's AIR road seat post. This hybrid carbon / titanium post, stunningly finished with a 3D-printed titanium topper, results in the smoothest possible ride quality.
