The reach on the geo chart looks long. What size is good for me? |
The short answer is that the reach number may be somewhat deceiving as the frame is designed to be run with a shorter stem. That, in combination with the comparatively steep seat angle, reduces the effective reach of the frame. Please reach out to sales@curvecycling.com if you have any questions about sizing. Read more about the GMX+ geometry here: GMX+ Geo Blog |
Why flat mount? |
There are very few drop-bar groupsets available with post mount calipers, so we decided to introduce flat mount on GMX+ Steel to make the groupset selection for drop bar setups easier. |
What are those black brackets on the downtube for? |
In order to reduce the number of holes and M5 mounts added to the downtube, and to add stability to the offset mounts, we decided to make these offset mount support guides specifically for the GMX+ Steel. These guides must be used when attaching bottle cages to the offset mounts. |
What are the extra plates with three holes I got with my SM or XS frame? |
These are adapter brackets for the rear M5 mounts so you can attach a regular bottle cage to the back of the chainstays and seatstays. The plate is not needed for sizes MD and up. |
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.
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.
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.

Please Note: | 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. |
If you are building your Curve frameset with a self-supplied groupset, please see the specification guid via the link below to ensure the necessary parts are sufficiently compatible with our framesets.
