The Evolution Of The Belgie

The Belgie series of road bikes was designed to bridge the gap between race and endurance. 

In 2018 Curve Cycling celebrated five years in business, and Steve Varga (Curve’s co-founder) turned 40. Steve decided to celebrate these milestones by designing the finest realisation of our Belgie. He wanted to explore innovation, showcase Melbourne cycling culture, and, of course, have the best 40th birthday present ever.

The AIR is our ultimate Belgie, which celebrates sophisticated artistry, performance, and a bike for those wanting something elegant and decorative.

  • Limited Release

    We have 23 Belgie AIR framesets available. Steve’s nominated quantity, to coincide with the date of his birthday, and his favourite ex-basketball player, perhaps the most popular jersey number in NBA history.

  • Bastion Collaboration

    Bastion consists of three former Toyota Engineers now using their expertise in developing the most technologically advanced bicycles worldwide, using in-house titanium 3D printing capabilities. Bastion regularly incorporates Curve wheelsets and forks in their builds, and we felt it made sense to create a frameset together that showcased the best of Melbourne bike builders.

  • Carbon Seat Tube and 3D Printed Topper

    The seat post is made from filament wound high modulus carbon fibre. They are manufactured here in Australia for cycling specific applications, according to Bastion engineering. The finished product features the Bastion signature weave, which is unique in appearance and properties.

    The finishing touch to the seat post is a 3D printed titanium topper engineered by Bastion. It is Ti6Al4V Grade 5 titanium, manufactured using Laser Bed Powder Fusion.

  • Custom Made to Order

    Every Belgie AIR frameset is custom-made to order. A professional bike fit is required as part of the process. Build time and assembly will take approximately six months once correct sizing is established.

    Pricing for the frameset alone is $7,699, full specs for sizing further below. You can buy now to simply secure a limited edition Belgie AIR. Curve will then be happy to talk through your desired build options. Complete build estimates for Dura-Ace Di2 or Etap AXS packages start from $14,000.
