- The Spirit -

A non-corporeal substance, the hub of emotions and character.
The defining feature of humanness, mediating between our body and soul
and completing us in ways we can only hope to fathom.

Belgie Spirit Columbus Steel All Road Bicycle

Indy-Pac Inspired Artwork

Well, we don't know much about non-corporeal substances,
but we do know about bicycles. When we made the Curve Belgie Spirit in Steel,
it was our mission to create a bicycle that completed you as a cyclist in ways that
can't be explained but just felt right.



As the "official bike" of the 5,500km Indian Pacific Wheel Race, we present the Belgie Spirit in glorious steel. We are only releasing 100 frames, each individually numbered, of this coast-to-coast inspired design, so secure your piece of history.
So if you're lucky enough to get your hands on one, it will be ready to take you the pub or cross continents.


We've designed this roadie to go long! It's got plenty of room for fat tyres offering a buttery smooth road ride, or a good ol' gravel grind.  
The bike is long, the BB is low, and the front is raised, so you can go go go, for hours or even days.
In honour of the 5,500km Indian Pacific Wheel Race, only 100 of these beauties will be released in this iteration of the Belgie Spirit.
Limited Release Bicycles
All frames are TIG welded by hand from a select combination of Columbus Spirit and Life tubing with Paragon Machine Works frame components.

Tubing made in Italy from Niobium steel – a light and strong material developed specifically for bicycle frames. We've chosen it for its many qualities including strength, stiffness, durability and longevity. The result is a lightweight bike with a truly lively ride quality that will last a lifetime.

    Development & Adventures

    The development frames have already undergone more miles of testing than most of us will cover in the next 5 years.

    Belgie Spirit Fixed Heart Perth Melbourne Cycling Adventure

    Perth to Melbourne with Fixed Heart
    Ben le Mesurier is extraordinary, a Curve mechanic and test rider, who rode from Perth to Melbourne solo to raise money and give back to the Melbourne Children’s Hospital who saved his life a decade ago. 
    Road-venture bikes must give you everything you need and nothing you don't. We've moved all bidon cages as low in the front triangle as possible allowing you to fit 2* one-litre bottles with enough space above for a frame bag. There is also a cage mount under the down tube for storing a tools & spares cannister, or more water.
    *Frame triangle storage is dependant on frame size.

    Belgie Spirit Steel FAQs


    Q - Is this what the Belgie will look like?

    A  - Pretty much – although artwork depicted here is a mock-up only so the actual product may vary very slightly.

    Q - Can I bring my own groupset and/or build kit (full or partial) to Curve or a Curve dealer to complete my build?

    A - Yes. No worries. Curve or a Curve dealer can help guide you through the process from start to finish.

    Q - How long will it take to receive my Belgie Spirit Steel frame?

    A - TBC once pre-sale period is announced. We'll keep you informed

    Q - Is the Belgie Spirit Steel available in a non-disc version?

    A - No. At this point it is not on the drawing board. Mainly because of caliper brake tyre clearance.

    Q - I would like a complete bike but different from the above spec. Can I still order it through Curve or a Curve dealer?

    A - Yes. No worries. We will treat it as a custom build. Almost any wish list you have can be catered for. Curve or your closest Curve dealer can handle it.
