Lighter and Sleeker

The Belgie ULTRA has thinner 16 mm seat stay tubing and an improved 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 to centre, and overall wheelbase across all sizes. A taller stack and more extended reach help make the ULTRA comfortable to ride all day long. This also helps improve the pesky toe overlap when using a wider tyre.

The ULTRA features our Race 370 fork, resulting in tyre clearance of up to 32 mm.

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.

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.
