  1. SPOKEN: Melbourne, Australia, 14-16 June, formerly the Handmade Bike Show Australia
  2. MADE Australia: Melbourne, Australia, 28-29 June
  3. BESPOKED Manchester, UK, 28-30 June 

Read on for more information about our 2024 show bike concepts.

AIR Belgie 3D

Curve Cycling AIR Belgie 3D high-end titanium / carbon road bike

This year Curve welcomes a new era for high-end road bikes with fully-internal cable routing and refined 3D-printed titanium details. Like the recently launched AIR Kev gravel bike, the AIR Belgie 3D features hybrid titanium / carbon construction. The 3D in the title, refers to the full 3D printed headtube, the feature differentiating this model from the AIR Belgie. While this bike 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. You will see it piloted by Curve's Sales Director, Ryan Flinn, in this year's 2,400 km Pan Celtic Race in July.

AIR Belgie

The AIR Belgie is a high-end road bike with hybrid titanium / carbon construction. The elegant internal routing is achieved with a standard 42/52 mm headset using the Columbus Trittico system. Most internally routed metal bikes make use of a larger top headset bearing which allow brake hoses and cables to fit between the steerer and top headset bearings. The cleverly shaped steerer on the Columbus Trittico fork allows a more elegant finish with a smaller top headset cup. While it's a subtle it results in a more refined internal routing execution. 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.

      AIR Kev

      Curve Cycling AIR Kev - Side View - Titanium Gravel Bike

      The AIR Kev is Curve's race oriented version of the much loved Kevin model (aka GXR). With a hybrid carbon / titanium construction, and 3D printed "power pyramid" at the seat tube / bottom bracket interface, the AIR Kev has the improved stiffness expected from a gravel race bike. Not just a stunning bike the AIR Kev can handle serious cycling adventures. To date, AIR Kevs have braved and survived mixed terrain bikepacking adventures across Europe and remote outback Australia.

      Tech Details

      All Curve Cycling frames are made from GR9 3Al-2.5V titanium tubing. 3D printed and CNC machined parts made are made from from GR5 6Al-4V+ titanium.

      Curve's proprietary "Power Pyramid" sits proudly atop the bottom bracket of the AIR Belgie 3D, AIR Belgie and AIR Kev. This meticulously designed 3D printed pat joins the bottom bracket shell to the carbon seat tube, and features a double-lap (double shear) joint to ensure superior bond strength in an area of the frame that sees high dynamic loads and stresses from pedaling. Thanks to the design freedom afforded by additive manufacturing, we've kept the structure hollow and carefully chosen the external and internal wall thicknesses to optimise the strength-to-weight ratio. The flared design adds to the aesthetic and helps stiffen the bottom bracket area resulting in improved pedaling performance.

      The 3D printed titanium seat post topper featured on all AIR seat posts has a hollow construction. Like the power pyramid, it also features a double-lap bonded joint to ensure a strong mating of carbon and titanium. The topper uses Enve's 2-bolt clamping system which is less prone to slipping compared to their previous 1-bolt system.

      The humble front derailleur clamp is an underappreciated part in the complete bike build kit, but it has an important role to play in the front shifting experience. We have deepened our appreciating of this fact through our recent 3D printed experiments. By stiffening the connection to the seat tube, Curve's 3D printed front derailleur clamp turns shaky front-shifting into definite, confident and precise gear changes on and off the big ring. We kept the design as minimal as possible with a countersunk mounting bolt and hidden clamp bolt. The clamp is designed to lock in the derailleur, providing solid support for its main body. It also has a special tang that eliminates the need for the small plastic wedge provided with SRAM AXS front derailleurs.

      With the AIR Belgie and AIR Belgie 3D prototypes, we have expanded on the AIR Kev concept and introduced hollow 3D printed UDH dropouts. The AIR Belgie 3D also incorporates a fully 3D printed head tube for an elegant front end.

      For the dropouts and the head tube, we've leveraged the design freedom afforded by additive manufacturing, keeping the structure completely hollow and carefully experimented with varying wall thicknesses to add strength where necessary and shaving weight where possible.
