The Curve Belgie Ultra is a titanium all-road bike that is as happy on paved, smooth roads as it is on lighter gravel roads or a weekend bike-packing expedition. Curve all-road bikes have been designed for a wide variety of terrain so you can enjoy bike adventures whenever and wherever you choose, and the Belgie Ultra does it all with a sublime ride feel and the kind of performance that has delivered ultra-distance race wins across the globe.

The Belgie Ultra was developed from the original Belgie (now in its third iteration), that Curve co-founder Jesse Carlsson’s rode to success in winning the 2015 Trans Am Bike Race. Curve wanted to develop the Belgie name further, with dirt road capabilities and adding to its load carrying capacity.

The Belgie Ultra features Curve’s Race 370 fork, resulting in plenty of clearance for tyres of up to 33 mm. In fact, both frame and fork can accommodate 33 mm CX/gravel tyres for greater off-road stability and grip, and a wee bit larger in a smoother tread tyre.

The Belgie Ultra features Bento Box mounting points on the top tube allowing riders to secure belongings in most bolt-on bike bags. Curve have also increased the size of the front triangle, allowing more storage capacity for top tube frame bags and water bottles, leading to ample room for bike-packing bags on all frameset sizes.

The latest Belgie Ultra also offers greater stability and an improved geometry with 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 toe overlap when using a wider tyre. This improved geometry makes the Ultra perfect for those long road kilometres, but also makes the Ultra perfect for fast, light gravel and rough back lanes and byways. If you are looking for something that is more focussed on race performance over paved road surfaces then it is worth checking out the Curve Belgie V3.

Make your Cappuccinos!
Color: White
I purchased this after a trip to France. I drank a lot of cafe cremes, pretty much like a cappuccino, and decided I need it in my like every day. Easy to use. Didn’t come with instructions but I was able to figure it out. Takes a little time but works well for what I want to achieve. Love the glass pitcher. Doesn’t spill when pouring. It’s very quiet while frothing super easy to clean. I love it!

Great frother
Color: Matte Black
It makes a great milk froth and heats well. One thing however, in spite of respecting the line limit it spills out and you have to clean the whole thing. So don’t fill it up to the line limit.

Thick foam for Cappuccinos
Color: White-Stainless, Color: White-Stainless
Comes with sevaral options including thin and thick foam, hot milk and cold foam. I used the thick foam for cappuccinos and I was impressed by the consistency. Not so much noise and easy to clean. The frother tools come off easily for cleaning the pitcher.

Very slow--5+ minutes to froth and warm milk
Color: White-Stainless
Pros-- Makes nice froth and warms the milk. Both froth settings produce the same kind of froth. it's relatively easy to clean-- usually just a strong rinse will do. It does fine in the dishwasher too. The noise level isn't bad. Cons--it takes between five and six minutes to froth milk. It is very slow. I can froth latte art milk on my espresso maker in less than a minute, by comparison. The forth it produces is too thick to make any kind of latte art.

Quality
Color: White-Stainless
What really impressed me is how fast it works—in just a couple of minutes, I have hot, creamy milk with thick, rich foam. The texture comes out smooth and fluffy, just like a coffee shop. It’s super easy to use, and cleaning it is quick too. I’ve used it for lattes, cappuccinos, and even hot chocolate, and it works perfectly every time. Definitely worth it if you want something quick, easy, and makes great foam in large amounts
