FAQs

Check HERE for further info regarding custom paint, bike set up and more.

I want to attach bags. What will it do to the frame finish?

Curve's steel frames are finished with high-quality and durable paint, but the paint is not unaffected by rubbing from bike bags or rock strikes etc.

If you want to keep your paint looking pristine, we recommend that you use some kind of protective film - especially in the high-wear areas where bag straps are in direct contact with the frame.

Stock Ti frames are not painted, but bag rub will affect the surface finish. The lighter, brushed, finish can be refreshed using a fine abrasive pad, but the darker blasted finish can only be refinished by media blasting. To keep your Ti frame looking pristine, we recommend using protective film.

I want to get a custom frame bag made. Can you give me the frame dimensions?

Of course! Have a look at our bagmaker page HERE where you can download full-scale PDFs showing the internal dimensions of all our frame models.

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 33 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.

Invest In Happiness

Curve titanium frames come with a Lifetime Warranty so that you can be sure the bike you love most will be the bike you love longest. We design every Curve product at our Abbotsford headquarters, then test them out in the real world, under the most demanding conditions.

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.

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.
