FAQs
FAQs
What's the process when getting a custom build?
The process always starts with a conversation, so get in touch and tell us about your Dream Bike, and we can advise on the best way to make that dream a reality. The next step is to put down a deposit (at least 50%) - this will get the product secured or ordered under your name and the build process underway. We'll be in touch as the build progresses with any updates.
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 not possible for us to know exactly which racks will be compatible. Before mounting a rack to your frame or fork, we strongly recommend you get in touch with us for our advice. We will do our best to verify compatibility.
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.
In general, M5 mounts on chainstays and seatstays will accept racks of various types, and the maximum approved weight to carry on a rack is 20kg (or less, depending on the rack rating).
Note: This rating is for smooth roads & gravel. For anything rougher, the weight limit decreases. Use careful discretion when gauging how much weight to carry on rough gravel or off-road adventures.
What payment options are there?
We accept payment in the form of credit card, Pay Pal and EFT. If you'd prefer to pay for your Curve bike or product in multiple payments, please contact us for an invoice with payment options attached.
How long will my order take to ship?
Some products can be shipped immediately and normally land within 10-15 business days. Other products will have a lead time depending on supply levels and build time. As a guide, complete bikes normally take 3-4 weeks, custom wheel builds take 2–3 weeks, and custom frames take 3-6 months, plus shipping time.
All our complete bikes are assembled and tuned before being packed safely for shipping (unless agreed otherwise). This means that you will not have to cut the chain, bleed brakes or set up and tune gears. However, in order for us to fit the bike in the box, some parts will have to come off. This means that some assembly is needed once you receive your new bike.
- Fit the front wheel
- Fit the handlebars on the stem (torque wrench needed)
- Fit the seatpost and adjust the saddle height and angle to your preference
- Fit the rear derailleur and chain *
- Fill sealant in tubeless tyres
* We realise that fitting the derailleur and chain may be something you're not comfortable doing yourself. We leave these parts off and pack them separately in the box to protect the bike and derailleur. The rear derailleur is one of the more expensive components on the bike, and we do not want you to receive your bike with a bent hanger, a broken or damaged derailleur, and/or a scratched chainstay due to chain rattle.
What's Different with the Belgie V3 compared to its Predecessor?
We've straightened out the seat stays and removed the old ‘brake bridge’ for a new sleeker and lighter behind. This means better tyre clearance, up to 32 mm. Upfront, the tapered head tube is taken straight from our Belgie AIR and utilises an integrated headset for some gram shedding and a sleeker finish.
A Size for Everyone
Are you an ‘extra medium’ or in-between size? Check out our sizing and geometry chart below and see that we've introduced more sizes to ensure your Belgie is the perfect fit.
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.
The Result
The Belgie is lighter and yet more versatile with increased tyre clearance. This race bike is just as comfortable racing a crit as it is exploring the back roads of the alpine region.
Travel in Comfort
At the core of each frame is a 3Al - 2.5V Grade 9 Aerospace grade titanium tube-set. This grade is optimal for bicycle frames and chosen for its stiffness, compliance, and durability balance. Titanium absorbs road noise without compromising on performance. There’s no buzzy feedback; it’s smooth as silk and very compliant so that you can spend more time on the bike. The Belgie V3 is just as comfortable racing a crit as exploring long climbs in the alpine region.
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.

We also have Bagmaker Drawings available for all frame sizes.

About a month ago I had my Belgie 3 (3.5 years old) rebuilt. The mechanical group set was tired so I replaced it with the SRAM Force wireless AXS D2 you beaut group set. 46-33 and a 10-36 casssette. The wonderful team at Curve took careful time and a fair bit of patience to work with me on the outcome. Quite a few rides in its like having a new bike. Getting used to the gearing has been fun but it has made a serious difference to the riding I do (lots of hills). It’s also been a handy fillip for easier gravel routes. Big thanks to the Curve crew!
There is something that verges on the spiritual about riding a bike, and - if I can't ride for a day or two - its absence leaves me feeling grumpy and a little down in the dumps. My Belgie, Preciousss, and I have been riding together for over 5 years now and every ride is still an experience of the simple joy that is cycling. I still enjoy a quiet, smooth and confident ride that I felt first up, something that only a well designed and made bike is capable of delivering. Preciousss is a key part of of my wellness, and I reckon she'll continue to be for a long time!
I was given the privilege of riding one of the very strictly limited Belgie AIR and what can I say. This bike simply does it all, at it's best. Whether it's in the flatlands, short and punchy climbs, long climbs up passes or twisty descents, the AIR goes through it all. Power and direction are transferred to the road very precisely, directly and without any losses. The quick and powerful response make any style of riding possible, if it's racing, training, exploring or some twisty local loops, you surely won't miss out on anything.
The bike consistently gives you the feeling of being fast, which turns out to not only being a feeling when you check your speed on the computer.
The ever shiny and exclusive design makes it an eye catcher, which shouldn't be parked in the garage, but be presented either out on the streets or in a good spot of your premises.
So I'm 18months into ownership of my Belgie v3, here in the UK, and what can I say.... its just an all round, awesome machine that can pretty much do anything you throw at it. I've covered 10,000miles already, through rain, snow, gales and scorching heat. brutal steep uk climbs, to most of the biggest Alpine ascents in France and Italy, and it ALWAYS feels so good, putting a massive grin on my face.... and above all these things, apart from still looking box-fresh, is the way in which it descends - truly phenomenal and quite literally the best bike I've owned in 30+ years of cycling... do yourself a favour and get one ordered, you'll never look back
I've had my Belgie V3 for nearly two months now. He's called Bertie ;)
Bertie is the most amazing bike I've ever ridden. I don't think I've ever been so comfortable on a bike. I have some old injuries and suffer from chronic pain so I'd accepted that riding up mountains or for long periods was going to cause me issues. I'd do whatever I could to mitigate it. I thought that was just the way it was going to be for me and I love cycling too much to stop.
At the end of November, I went to Bright and I rode up Mount Buffalo (7th time) and Mount Hotham (first time for me). Riding up mountains has always been hard for me because of an old back injury (prolapsed disc) but this time I managed to get up Mount Buffalo with no pain at all. Well, there was pain when some sweat laced with sunscreen got in my eye but that's not Bertie's fault. I even managed the 110km Hotham ride with just a few twinges.
What you've managed to achieve is nothing short of astonishing. I never thought I'd be able to ride without some degree of discomfort but now I know it really is possible. The bike fit I had done undoubtedly helped fit Bertie to me exactly but that was only possible because you've made such an amazing bike.
Thanks for giving me a machine for freedom and joy.
