Choosing a top of the range, made-to-measure road bike is a big moment.

After all, you’ll never need to buy a bike again. And you’ll spend so much quality time together in the most legendary places. What’s different about buying a Jaegher is that, unlike in a regular bike shop, all the decisions are yours. At Jaegher, we don’t start building your bike until we know exactly what you need: your goals, your measurements, your geometry and your paintwork. We all want this to be the perfect experience, so we expect you to have a lot of questions. If you have a look around the website you’ll find some answers, but here we’ll dig a little deeper still to answer the questions people ask most often. We divided our Q&A into four sections: Questions about the choice of your frame set, questions about custom-made frames, questions about technology, and finally questions about ordering and delivery. If your question – or answer – isn’t here, don’t hesitate to send a mail to We’ll respond within two working days.


The choice of your frameset depends on what you, and your body, prefer. If you want a more aggressive geometry for better speed, then look no further than the Interceptor Flymaster. If you want a timeless look, then the Interceptor Classic with its horizontal top tube is the one for you. If you’re into a classic look with lugs and thinner tubes – the kind of bikes we made for the finest rider of the 70s and perhaps all time – then only the Phantom Authentic will do.

I love to climb. What’s the best cycle for me?

Every Jaegher is made to climb. There’s only a difference of 100 to 300 grams between the different frames. Our lightest frame is 1300 grams. So even for climbing, it will be your personal choices and needs that will determine which frame you buy. Some cyclists like a dynamic short wheelbase for climbing; others just look at weight. A fully built Jaegher with top range parts will be between 6.4 and 7 kilos. And you probably know that the UCI minimum weight is 6.8 kg. That’s why we call it Airlight Steel. Everyone who lifts a Jaegher for the first time can’t believe it’s a steel bike. And every time we have to confirm, “Yes, it’s really steel”.

“It’s terrifying. Some road bikes feel like a dishcloth in a descent.”

Johan Musseeuw.

Climbing is one thing, but equally – or even more important – is the behaviour of the bike during a descent. Riding a steel bike gives you a unique and liberating sense of safety. Plus, as we say in Belgium, they’ll eat up the curves.

What is the stiffest road bike you have?

The Interceptor Flymaster with a short wheelbase is definitely the stiffest Jaegher. This was only possible because the engineers of Columbus and Jaegher worked together to create a unique oval Columbus Spirit tube set. The perfect marriage: stiff, light and smooths out rough roads. The Flymaster has a tapered head tube, increasing its stiffness even more.

What’s the lightest frame you have?

Our lightest road bike is the Interceptor Classic. But don’t compare its thin tubes with the bikes of the 70s and 80s, today Jaegher uses only the most advanced and the highest quality steel. The lightest fully-built Interceptor left our workshop at precisely 6.6 kilos, and it was a size 56. And you know that’s too light to be admitted in the Tour de France!

What’s the weight of a frameset?

The weight of a frame depends on a number of things: the model, the size, brazed lugs or welded joints, and the use of paint. But there’s barely a difference between the Interceptor Flymaster and the Classic. The Classic weights about 35 grams more. That’s like one gulp from your drinking bottle. And then there’s also the Phantom Authentic. It has thinner tubes, but that weight advantage is offset by the lugs.

Is the Panthom Authentic — the vintage road bike— exactly like it was in the 70’s?

No, the Phantom is way better. We had a few arguments about it at Jaegher. We could have made it exactly like we made here in the workshop over 40 years ago, but decided to make a better version, with superior lugging, the latest technology, stiffer and lighter tubes. Jaegher stands for the best in road bikes, not nostalgia. The engineers at Columbus kept doing their magic. The tubes for lugged bikes are slightly thicker (but thinner than the Ascender and Interceptor) and that means the lugs are bigger too. Also, the head tube we now use improves the bike’s stability and the bracket is better too. So the lugged Phantom isn’t just lighter, its stiffer and more stable than his grandfather from the 70s. But if you really want a vintage bike, we still have some tubesets and lugs from the 70s. And now we’re maybe one of the only companies in the world that can make you a frame from the 70s – made to measure. But sorry, it won’t be cheap.

Is it possible to turn my Phantom, Interceptor or Ascender in a Randonneur?

All Jaegher frames are robust enough to be used for randonneuring without any problem. We can weld on the necessary bits to the frame and pieces for mudguards, lights, and paniers before we paint it. The Belgian Kristof Allegaert, the world’s best long distance cyclist, is a total Jaegher fan. He didn’t turn his Jaegher into a randonneur, but he does carry bags on tours ranging from 500 to 10,000 km. He won the ultra-distance Transcontinental Race, with both an Interceptor Classic and a Flymaster, the Trans-Siberian on an Ascender and the tragic Indian Pacific on a Flymaster.

Do you also make pistiers or track bikes?

We can turn just about every model we have into a track bike. The most important thing is to adapt the geometry. The bracket sits higher to keep the pedals from touching the track in the most extreme curves (the “Kuipke” in Ghent it’s 52%).

Is it possible to order a made to measure steel mountain bike from Jaegher?

Yes, it’s possible. We’ve made some mountain bikes at the workshop, and we think they turned out very well. Just send a mail to with your wishes and we’ll see what we can do.

What is the best Jaegher for long distance stages?

Kristof Allegaert would say that it’s a Jaegher, even if we think his success also has something to do with, well, Kristof Allegaert. With his Jaegher bikes he has won three Trans-Continental Races (4,000 km), the Red Bull Trans-Siberian Extreme (9,150 km) and the tragic Indian Pacific (5,500 km). He won these races riding the Interceptor Classic, Ascender and Interceptor Flymaster. The other constant in these victories is that … all his bikes were red. But, if you’re not Kristof Allegaert we think The Ascender Classic is our most comfortable bike for long distances.

How can I order my Jaegher?

Just send us a mail at or make an appointment to stop by our workshop in Ghent. We have the tools to take your measurements. We’ll help you choose your frame, the paintwork and all of the components you’ll need to make a world class bike. If you decide to order your Jaegher on this website, we recommend going to a professional bike fitting centre for the measurements we’ll need to build your frame.
