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.

 

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

Great choice
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
After I suffered a second-degree burn from steam, I was told by my doctor that I would have to keep my new fresh skin sun-blocked for up to a year to avoid any scarring or hyper pigmentation. This has been a great selection as it is a roll-on, Which helps a lot with preventing messes that can happen with traditional sunblock bottles. I also like that it is easy to travel with, and the fact that it is zinc based.

My favorite new mineral sunscreen!
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
This is my favorite new mineral sunscreen! I've been searching for years for a product that is easy to apply, not messy, and doesn't show up too white. This roll-on is the perfect solution. I keep it near the front door and quickly roll the sunscreen on my hands, arms, and chest before leaving the house. The sunscreen applies so quickly and uniformly-- there are no bare spots or messy globs to rub in. Also, the roll-on keeps the sunscreen from oozing out of the tube and getting all over everything. Finally, the roll-on method also eliminates the frustration of having half-filled tubes and pumps where you can't even access the sunscreen when the tube gets low. Here's hoping this doesn't happen with the roll-on. Thank you Sun Bum for creating this wonderful product. I also love the reasonable price.

great product - it must be blended in well
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Love this stuff. The roll-on makes it easy to apply on the go. It leaves a white streak unless you blend it in. I don't mind the white streak - at least I know I applied the product.

I love the roll on sunscreen. It is quicker to apply and my little one can help without squeezing sunscreen everywhere. Will buy again.
