Curve - Belgie ULTRA

Where It All Started

The Belgie is affectionately named after Melbourne's infamous "Belgie Ride,” a short, sharp, mixed terrain shop ride that often resembles a CX race rather than a road ride.

Then after Jesse’s success in winning the 2015 Trans Am Bike Race, we wanted to develop the Belgie name further, highlighting the spirit of Australian endurance cycling. So the Belgie SPIRIT was born in 2016 to take on the 5,545km Indian Pacific Wheel Race, celebrating the rich history of the Overlanders from the 1890s. 

Furthermore, through feedback from endurance riders and athletes worldwide, we continued to develop this frame again, improving handling, cornering, clearance for light gravel tyres and now featuring bento box mounting points. As a result, we now call this version the Belgie ULTRA.

Lighter and Sleeker

The Belgie ULTRA has thinner 16 mm seat stay tubing and an updated tapered head tube, resulting in a sleeker frame design and considerable weight savings.
At 1630 grams, the Belgie ULTRA 56 frame is 180 grams lighter than the previous model.

Mechanical versus Electric

Thanks to some improvements in engineering, the Belgie frame is now compatible with both electronic and mechanical gear systems. So you can now have your pick of eTap, Di2, or standard mechanical options.

Stability and Improved Geometry

Longer chainstays, front centre, and overall wheelbase across all sizes. A taller stack and extended reach help make the ULTRA more comfortable on day long rides. This also helps minimise pesky toe overlap when using a wider tyre. This improved geometry makes the Ultra perfect for those long road kilometres, but also makes the Ultra perfect for fast, light gravel.
The ULTRA features our Race 370 fork, resulting in tyre clearance of up to 33 mm. Both frame and fork can accomodate 33 mm CX/gravel tyres for greater off-road stability and grip.

Bento Box + Extra Storage Space

The Belgie ULTRA features Bento Box mounting points on the top tube allowing riders to secure belongings in most bolt-on bike bags. We have also increased the size of the front triangle, allowing more storage capacity for top tube frame bags and water bottles.

There is ample room for bikepacking bags on all frameset sizes.

Want to Carry More?

With a wide range of frame and fork mounted rack systems on the market, and with more appearing every week, it is important to understand which rack systems are compatible with your Curve frame and fork, and how to mount them correctly in order to ensure safe riding, avoid damage and voiding your warranty. Before mounting a rack, we strongly recommend you get in touch with us to confirm compatibility and the correct mounting procedure. This will minimise the risk of injury, product damage and voiding your warranty. Your local Curve dealer, or the team at Curve HQ, can also help you select a rack system and mount it to your bike for you.

All bikes purchased from iRIDE will have been pre-assembled by our mechanics and test ridden. You will also receive a multi point checklist of all the safety checks and bike build elements we work through to ensure you bike is correctly assembled, and then tested so that it runs as it should. Bikes being sent to a customer who is unable to collect it from iRIDE, will have it boxed, wheels, saddle and bars generally off and re-packaged.

The delivery of bikes will be organized once a freight fee can be determined based on weight and delivery location.

Assembly should take no longer than 10-20 minutes. It is recommended that a skilled mechanic assemble, or check the bike. If possible your local bike shop is likely best placed to do this from a safety perspective to ensure all is as it should be. If a rider is having any issues we can hook up an online video chat, or talk over the phone. If this service is required email us at workshop@iride.net.nz to organise a time that suits all parties.
