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.

Great turned to not so great
My Doberman (80 pounds in 7 months) puppy absolutely loved this ball. He loves anything noise making so this ball was perfect. Unfortunately, about 2 hours of nonstop play the cover was falling apart. There was no saving in. My pup is rough on toys and this one couldn’t handle it. I let him play without the cover for a little bit but the plastic is VERY hard. I’m not sure what type of plastic it is, but it’s very hard, no your average plastic. It was clunking around and banging into everything possible. I would love to give it more stars as it might have been perfect for other dogs, or maybe I just got a dud. But having to take the ball away from him was almost heart breaking. Those sad puppy dog ever and him looking everywhere for it. Barking nonstop because, well he want his ball….and being a puppy he is still learning. Had the cover held up for even 24 hours it would have been great. So I have a sad puppy and a lighter pocketbook. It was fun while it lasted.

Lasted less than a week.
Size: Small Size
This ball was delivered on March 7. It was fun while it lasted, but Today, less than one week later, the squeaker which was the unique fun part of this ball, is dead. The ball is still intact, the soft cover still on it, so our corgi never got to the squeaker - it just stopped making sound. Given the point of this ball is to engage a dog to chase after like it was squealing prey, the death of the squeaker is very disappointing.

Glow in the dark dog ball
If u shine a bright light on these balls they glow for 15 min. My dog has a double coat and I live in fl so I play outside at night and this glow ball fits the bill. Lots of fun. The ball is made well and so far has survived the jaws of my king shepherd. Im happy with my purchase and have also purchased them for family and friends

Glowing Orbs can be fun.
My dog loves these balls. He can’t break them, which is hilarious. The fact that they glow and double as a cognitive toy when you hide treats inside is a huge bonus. My dog is literally darker than the night. We leave the ball near a lamp for 10–15 minutes, then take it outside and throw it. Watching a pitch-black blur sprint at full speed and suddenly seeing a glowing orb bouncing through the night is unreal. Great toy. Highly recommend.

The ideal fetch ball
Our dog is obsessed with these. They bounce well, they’re squishy enough to meet his chewing needs but strong enough to not get destroyed. We do replace them every 8-10 months because after 2-3 20 min fetch sessions almost everyday they do rip. They have a nice weight to them so they’re easy to hurl 20-30 yards.
