Stainless steel is the unrivaled champion in the performance-comfort balance, and when it comes to aesthetics, nothing surpasses a meticulously handcrafted stainless steel bike. Its style is unmatched, its durability enduring, and its essence pure. Crafted to fit you flawlessly with exceptional geometry, stainless steel stands alone as our material of choice. We don't dabble in carbon, titanium, or any other frames – steel simply stands as the ultimate choice for crafting the finest bikes.
"There's a compelling reason why the world's most prestigious watchmakers, including Rolex, Patek Philippe, Jaeger-LeCoultre, Audemars Piguet, IWC Schaffhausen, ...opt for high-end stainless steel."
THE FINEST STEEL — ASCENDER AND HURRICANE — MAKES AN END TO GRAVITY.
ONLY A FEW HIGHLY SPECIALIZED WELDERS CAN HANDLE THIS FINEST OF STEELS.
JAEGHER, MADE WITH THE NEWEST GENERATION OF ULTRALIGHT ITALIAN STEEL.
FL.X — 1912
These combined benefits make stainless steel the most attractive option for riders seeking durability, performance, aesthetics, and environmental sustainability in their frames.
Jaegher finest framesets, the FL.X series, are handcrafted out of exclusively for Jaegher made Columbus XCr tubes. All what’s great about cycling comes together in this timeless masterpiece. Stiffness meets responsive characteristics, meets outstanding vibration absorbing quality, meets lightweight, meets pure aesthetics. This bespoke, handcrafted, and welded in a second to none geometry results in a frameset with maximum dynamic efficiency and an unbeatable performance-comfort ratio.
The unique feel of steel is difficult to translate into statistics and numbers. The weight/stiffness ratio of our FL.X frame is superior than titanium or aluminium while it’s vibration absorbing quality beats easily those from carbon or aluminum.
The frame — material and geometry — sets the standard for excellence in cycling.
The Most Heroic Sport
On Earth Deserves
The Best Material
That Is Known To Man
To Build A Frame.
Even If It Takes
More Time, More Sweat
And More Swearing.
Innovation in steel tubing hasn't stopped. Stainless steel inherent stiffness lets you build with small, graceful, tubing and its tensile strength allows for the tubing to be butted almost paper-thin. It's these material attributes, combined with steel's natural fatigue resistance that produces a frame that feels famously alive underneath you. For aficionados of that feeling we present the answer: a perfect 21th century steel racing bike, manufactured with an exclusively made for Jaegher Columbus tubeset.
The intense material of our frames is so hard it requires the maximum of our machines and the XCr tube set is so light and thin-walled only the highest skilled craftspeople can handle this finest of all steels. This effort you will feel in every pedal stroke.

The Ascender series for the road and the Hurricane series for allroad. FL stands for Flanders, the beating heart of cycling. X stands for Stainless Steel or XCr, the finest material from which to create world class race cycles.
EVERY JAEGHER IS A
TRULY SINGULAR CREATION.
Jaegher frames are made of high-end Italian steel. The steel alloys of the newest generation are ultra-lightweight. Jaegher works exclusively with the top of the range, Columbus Spirit and XCr tubes: reinforced at the ends, thin and light in the middle. Jaegher works in close partnership with Columbus Italia. Together we developed tubes and tube-sets to create unique frames that perform even better. This makes your Jaegher one of the best steel or stainless steel road bikes ever made – with a ride quality that is incomparable.
The weight of our frames rivals that of other materials. A Jaegher frame weighs between 1.2 and 1.8 kg. We have built complete road bikes with a weight of 6.7 kg, which is even under the UCI limit of 6.8kg — and the Tour de France. But on the other hand. Isn’t that weight thing overrated? Maybe because it’s the only thing we can do in the bicycle shop. Just lift the bike to feel how light it is. It’s also the only thing we can compare. Grams.
A lot of pro-riders are afraid of a road bike that is too light. Because every climb is followed by a descent. They don’t want – in the words of one of the best cyclists of the world – a road bike that feels like a dishcloth. A road bike needs to give you confidence on the hill, on the cobbles and when sprinting. But most important of all. Your race cycle has to give you endless pleasure and eternal satisfaction. And that is exactly what a Jaegher does.
Jaegher only chooses top of the range materials: Columbus Spirit and XCr tubes.
The tubeset of our Ascender, Hurricane, Interceptor and Tornado consist of custom made tubes by Columbus Tubi, exclusively for Jaegher.
The cutting edge steel tubes Jaegher uses for building it's tubesets is from Columbus Italia, the world’s oldest bicycle tubing manufacturer. Over the last 5 years Columbus has transformed from a high volume industrial manufacturer of performance bicycle tubing into a small laboratory dedicated to individually producing small batches of avant-garde steel tubes pushed to the absolute limits of their metallurgic possibilities. It was the company’s discovery and refinement of new “special steels” with greatly increased ductility and Ultimate Tensile Strength in the early 2000s which first paved the way for these changes. To put things in perspective: in the past even one-off special tubes, such as those Columbus produced for Francesco Moser’s hour record in 1984 or other custom-tweaked lots for demanding professional riders, were only drawn a maximum of 2 times, to arrive at wall thicknesses of 0,5mm. But the special steel alloys developed and worked by Columbus today – combined with the company’s ability to develop more complex, almost artisanal, production techniques – allow workers to
1 — draw each tube to wall thickness as thin as 0,38mm without compromising fatigue life, reducing contemporary steel frame weights by as much as 500 g and
2— draw each tube up to 4-5 times (with a 65% reduction of linear mass without annealing, compared to 55% in older steels). The ability to repeatedly draw a tube has allowed Columbus to radically alter the micrographic structure of the steel, making it far finer and more orientated than was ever previously possible. The result is a metallurgically flawless, ultralight, extremely stiff tube whose characteristics will remain entirely unaltered for generations of riding.
The most advanced result of this period of innovation has been the development of XCr, the world’s only bi-phasic martensitic seamless stainless steel bicycle tube. A Columbus XCr tube can reach wall thickness of 0,35mm and, crucially, is drawn 12-15 times. This unparalled possibility for repeated drawing cycles of the same tube allows Columbus to continuously enhance the already extraordinary intrinsic metallurgic qualities of XCr steel, resulting in a stiffness-to-weight and UTS/weight ratio superior to that of any titanium or aluminum currently in use for bicycle manufacturing.
It’s not a secret. It’s too much about trends and fashion in the cycle-industry. Extreme oversized tubes, funny curves, ridiculous contrasts between thin and thick what results in dangerous limits on the most crucial zones of a race-cycle. We don’t go there. We don’t want to hide our geometry by making a race-cycle like a seasonal dress. Of course we are part of the evolution in positioning on the cycle, seeking for the most performant geometry, the composition of the steel tubes and welding techniques. On the other hand we don’t have the urge to hide those unbeatable and still most performant lines of a race-cycle. We are proud on them.
Bespoke starts where made-to-measure stops. Bespoke fit much better than made to measure and takes much more time. Small, medium or large. All too often, this is your choice when you’re buying a new bike. Then you are fitted to the frame with a longer or shorter seatpost and stem, and a ridiculous amount of spacers on top, because your cycling shop has to get rid of their stock because the new collection with fancy colours is arriving. Obviously, mass manufacturers try to reduce their production costs, and they do this by limiting the number of moulds they need for the frame. At Jaegher we start with you. Our experts take your measurements, down to the last detail. Then we talk about what your expectations are — and only then we start building your frame, tube by tube. If you can’t come to us, go to your local expert for a bike fitting and send us your measurements. Welding a steel frame takes time and craftsmanship, but we wouldn’t do it any other way. Jaegher has stayed true to its steel roots in frame-building.
The weight/stiffness ratio of our FL.X frame is superior than titanium, aluminium or steel while it’s vibration absorbing quality beats easily those from carbon or aluminum. Stainless steel is the most rigid and responsive of all steel race cycles. This allows a stainless frame to absorb the “road buzz”, while it’s stiffness means that each pedal stroke is transferred into pure speed. This unrivaled comfort and road feel doesn’t just feel good, they also improve your performance. You’ll remain fresh and more alert for longer. The unique feel of our FL.X series is difficult to translate into statistics and numbers. Still too much riders care about statistics on paper and follow blindly the mainstream. The difference happens out there — on the road, the cobbles, the curves, the hills, the descends and gravel paths.
"Speed, trust and comfort, that’s what you expect from a road bike." Kristof Allegaert, world’s best long distance rider.
It’s not a very well-kept secret that some materials lose their strength with time. This includes the resin holding the fibres together in a carbon frame when microscopic cracks form in the layers. Another problem with carbon is it’s fragile. When hit hard it breaks. Jaegher frames are made of high-end Columbus Spirit and XCr alloys and are – what else? – hard as steel. They keep their strength for life. Did you ever wondered what happened with those high-end carbon frames after a race like Paris-Roubaix?
Carbon fibre has a dirty secret: the hi-tech material is extremely wasteful to produce and difficult to recycle. Unfortunately there’s still no effective way to recycle and reuse carbon fibre. In a Jaegher frame you won’t find any non-recyclable fibres : simply the best and most honest steel. And if there is an accident don’t throw your Jaegher frame on the rubbish pile – we can repair it.
We are not more holy than the Pope. There's also carbon in our groupsets, handle bars, seat posts and wheel sets. Those parts are not more recyclable than a carbon frame, but al least they have less impact on the ride qualities and are less fragile than a carbon frame.
The premium steel tubes we use to built your frame are from Italy. The design, measuring, miter cutting, welding, paintwork, assembling...happens in Flanders, the beating heart of cycling.
A lot of brands don't dare to talk about this item. That's exactly why we do. To make money in the cycling industry or any industry you have to bring down the production cost to an absolute minimum. We arrived at a stage where the production cost of a carbon frame of a famous brand is between 30$ en 100$. Are we jealous of them? Yes, because they make a lot of money. Are we proud? Absolutely. Because we make much better and long-term race cycles.
6.7 KG. SO WHAT?
We build a complete road bike with a weight of 6.7 kg, which is even under the UCI limit. But we don't let weight define our bikes. When it comes to performance, weight is only part of the equation — and it's not even the most important part. Just because it doesn't matter how light your bike is if it doesn't fit perfectly your riding style or needs.
— A bike with a perfect geometry is one where performance, comfort and balance are in perfect harmony.
We focus on optimizing every aspect of your bike to ensure that it perform optimal across all categories: speed, comfort, handling, efficiency...and more.

ALLEGAERT, WORLD'S BEST ULTRA RACER UNDERSTANDS THE INCOMPARABLE ADVANTAGES OF A STEEL OR STAINLESS RACE CYCLE.
While the majority of its competitors went for a titanium race cycle, Allegaert stood out by selecting steel or stainless steel. When asked why he chose Jaegher, he immediately says it was love at first sight. The quality of the Belgian brand, the steel they work with, the custom fit, and the gorgeous appearance. When we ask him about the red colour, he says he loves the simplicity and fierceness of it.
