CURVE Air Belgie

The Evolution Of The Belgie

The AIR Belgie accelerates Curve's much loved Belgie road bike range to a new level both in performance and aesthetics. This high-end road bike with hybrid titanium / carbon construction is bonded, finished and painted in Australia.

While the AIR Belgie is a rolling work of art, like all Curve bikes, it is built to be ridden. Designed with stiffness, performance and durability in mind, a less robust earlier prototype even passed EFBE's daunting test regime. This bike will handle serious endurance missions.

The elegant internal routing execution uses the Columbus Trittico system which allows hidden hoses without an oversized headtube. Stunning 3D printed details adorn the frame, from the refined dropout design to the power pyramid bottom bracket assembly.

The AIR Belgie has a conventional welded headtube constructed with precision CNC machining. This distinguishes it from the AIR Belgie 3D which has a fully 3D printed top tube.

• Stunning Power Transfer Without Compromising Comfort
  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.
  
  
  
• Finished in Australia
  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.
  
  
  
• Internal Routing
  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.
  
  
  
• High Resolution 3D Printing
  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.
