All Road, All Day

Curve Titanium Road Bike

A SHORT HISTORY OF THE BELGIE SPIRIT 

Curve's rich history was founded upon adventure cycling, and our bikes are often designed with a specific reason or adventure in mind. 

After Jesse’s success in winning the 2015 Trans Am Bike Race, we wanted to take the Belgie Classic further and capture the spirit of Australian endurance cycling, so we designed the Belgie Spirit to take on the 5,545km Indian Pacific Wheel Race and celebrate the rich history of the Overlanders from the 1890’s. 

Released in 2016, the Spirit was optimised for long days in the saddle on all types of road. It would tackle cobbles and light gravel with confidence, helped by wider tyre clearance and a lengthened wheelbase. It’s been enjoyed by ultra-endurance cyclists, commuters, reactionists, rail-trailers and racers; it’s a true all-road bike! 

Over the years this bike has seen many adventures, more than we can possibly recount without signing a book deal… So with our accumulated knowledge and experience, we decided to refine and tweak the Spirit into a better version of itself, which we now call the...

ULTRA!


Our Spirit goes Ultra.

FAQs

When shipping direct, how does a complete bike come finished to me? Each bike built and boxed to "90% complete" with the fork steerer uncut and bar tape is not wrapped. We do this so each individual can personalise their setup options. This final procedure should be preformed by an experienced bike mechanic.
