Curve Belgie ULTRA

Curve's rich history was founded upon adventure cycling and their motto of #RaceRideSeek, this adventurous spirit is reflected in the engineering of their bikes.

After Jesse’s success in winning the 2015 Trans Am Bike Race, Curve wanted to spread the name of the Belgie further and capture the spirit of Australian endurance cycling, so they 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 back in 2016, the Spirit was a hit with all who rode it, and those who didn't! A bike optimised for long days in the saddle on all types of road, has made it the weapon of choice for all kinds of riders. It’s been enjoyed by ultra-endurance cyclists, commuters, roadies, randonneurs and ordinary cyclists looking for a comfortable high-end road bike.

These bikes have been taken all over the globe on adventures of epic proportion. Some of which are recounted over on Curve's website, others here on G!RO, others elsewhere and many yet to be written, this bike is not short of inspirational tales. Curve accumulated all this real world experience and knowledge, and refined it into an ULTRA sleek package! And thus giving way to the transition from Spirit to ULTRA.

As well as being luxurious and speedy on the tarmac, the Ultra is happy tackling cobbles and light gravel with confidence, helped by wider tyre clearance and a lengthened wheelbase. You’ll soon discover your spirit of adventure with this titanium all-round all-roader.

After consultation with some of the best ultra-endurance racers in the world, Curve designed the Ultra to provide the solid and stable quality of the Spirit, while improving on its cornering ability and handling.

Invest in happiness

Curve design and test all their products through their Abbotsford headquarters, riding in the toughest real world conditions.

Lighter & Sleeker

New thinner 16mm seat stay tubing and a new tapered headtube results in sleeker frame design and considerable weight saving. At 1630g the Belgie Ultra 56 frame is 180g lighter.

Stability & All Day Geometry

Longer chainstays and overall wheel base across all sizes, plus a taller stack and longer reach helps make the Ultra comfortable enough to enjoy all day.

Mind Your Toes

Longer front-centre to minimise toe overlap with wider tyres.

Bigger Tyres

Can fit up to 700 x 35C
NOTE: Curve's testing was using Vittoria Terreno Zero 35C, some knobbly gravel tyres may not provide enough mud clearance.

More Load & a Bento Box

Curve have added Bento Box mounts on the top tube and increased the size of the front triangle, improving storage capacity for top tube frame bags and water bottles. Repositioning bottle cage mounts also aid with bags and bottle clearance.

Mech. vs Elec.

Thanks to some clever engineering, the frame is now compatible with both electronic and mechanical running gear. So you can forever switch between eTap, Di2 or mechanical shifting options and not worry about upgrading from mechanical down the line!
