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.
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. To make sure current, prospective or custom bagging fits your frame size please see our Bagmaker Drawing page.
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.

Important Note: Please be aware that due to the steerer length of the Ride 370 fork (300mm), when paired with Ultra frames in sizes 61 and 64 only 10mm and 0mm of spacers will fit under the stem, respectively, due to the longer headtubes (61 cm - 240 mm, 64 cm - 250 mm).
If more stack is needed, an alternate fork with a longer steerer tube may be required. Please Contact Us to talk through possible options if this may affect you.
