I remember that first jump when I was sitting on a new steel-framed bike. My heart was pounding, and adrenaline was surging as I slowly picked up speed towards the ramp. When I lifted the bike off the ground, I felt the entire frame flex slightly – not dramatically, but more naturally, as if it was speaking to me. I instantly fell in love with that feeling of liveliness and confidence. It was different from all the, let's say, "school" aluminum frames.
At that moment, I understood that steel is more than just a number in a catalog. It's a material that can convey emotions, that breathes with the rider. It's not a cold data table, but rather an old friend who knows how to respond to a hard impact with a sensitive touch. At that moment, as a rider, I felt the connection of the bike with my body and mind – the bike worked with me, not against me. I realized that behind the numbers and tables lies a true connection – how the material reacts under our feet.
When a designer thinks about material
As a developer and designer at Dirtparade, I know that steel frames aren't an automatic choice for everyone. Technology and trends are constantly changing around us. But this is precisely where we need to stop and think: What am I really looking for when I develop a bike? Weight? Lightness? That's certainly important, especially when it comes to top-tier racing machines. But to the same extent, I'm looking for the character and feel of the bike on the track.
When designing a frame, I consider where the frame should flex and how the material behaves under demanding impacts and shockwaves. Steel (especially alloy chromoly, like 4130 CrMo) has an excellent strength-to-flexibility and durability ratio. This doesn't just mean you won't break it on the first jump, but also that the bike has a certain feedback when riding. Every stressed point of the frame works, flexing slightly, more than a stiff aluminum construction. And I know that this subtle movement is very important for the rider – it helps them gauge whether everything is working as it should.
When I build a frame, I want to find the perfect balance between flexibility and rigidity. That's why I often fine-tune the geometry and the strength of individual tubes. In areas where I expect strong impacts and hard landings, I add material to maintain stiffness. Where the frame can breathe, I remove material – but only enough to keep it strong. The result is a bike that is agile in flexion where energy needs to be absorbed, and strong where power needs to be transferred to conquer the terrain. It's the art of compromise, and the flexibility of steel gives us sufficient freedom in this regard.
Also, during steel welding, the material structure often changes less than with aluminum. Steel can withstand welding heat and retains most of its properties at the weld, whereas with aluminum, strengthening the joint requires more consideration. Realizing this made a lot of sense to me: the bike is thus positioned in the middle layer between stiffness and flexibility.
On trails and bikeparks – steel in action
I'm not just a fanatic about charts and tests; I'm primarily a rider, and that's why I'm mainly interested in how the bike behaves when I get my body moving on bikepark jumps or trails. I remember the first time I rode concrete walls and pumptracks on a steel frame. When pumping, I felt like the frame was pushing behind me a bit, as if it was catching every beat of the drums in the seat. Flexible steel supports every movement. On hard landings, the frame flexes slightly; the steel naturally dampens the initial impact. And those subtle vibrations and movements help me maintain contact with the terrain and feel what's really happening under the bike.
I remember once comparing a jump at the same spot with aluminum and then with steel. On the aluminum bike, I felt almost like on a stiff board – everything landed instantly hard. On the steel frame, upon landing, there was first a gentle flex of the entire chassis, and then a "click" sound, as if the material had an internal damper. I wouldn't use that word in that sense, but it was as if the frame naturally softened the blow. This situation is incredibly difficult to describe without riding – you have to experience it to understand what a difference it truly makes.
Control is another thing. Thanks to the strength of the steel frame, I felt that the bike never deviated from its course during sharp turns or sustained pedaling from the top of a jump. The frame doesn't twist, even if I occasionally push it harder than it should handle. This gives me confidence; you know exactly what the bike will do, even at the extreme. This readability, as I call it, reinforces my certainty.
Another thing is stability: on a steel bike, I feel that even after a ten-hour marathon over varied terrain, the frame won't give out on me – on the contrary, it propels me forward. I recall, for example, a fantastic week in the woods when my friends and I were kicking up dust and changing lines. Even after hundreds of landings, the feeling of the ride remained consistent. It's as if the steel tubes "self-wound" energy during the ride and returned it controllably with each pedal stroke.

Reality and Compromises
But I'm not suggesting that steel is flawless. On the contrary – the truth is that every choice brings compromises. The most striking is the weight: a steel frame will usually be heavier than an aluminum one. The lighter the bike, the easier it is to handle and accelerate, which everyone probably feels. It's said that in dirt style, strength and stability matter more (after all, I won't get a heavy, cheaper case of sweat), but every extra gram counts. That's why we look for where steel needs a thicker wall for strength, and where we can reduce it to keep the weight down.
Another consideration is corrosion. Steel is prone to oxidation if left outdoors. For a dirt bike that gets a good dose of water and mud, it's therefore important to consider paints and protection. We strive to choose the best possible finishes – from powder coating to wet painting. It's an extra concern. But I believe that a bike you take care of will eventually repay you. A steel frame can last decades if properly maintained. This idea – investing a little effort today to gain years of guarantees – seems meaningful to me.
And then there's the cost and labor involved in manufacturing. It's a sacred truth – making a steel frame is demanding work worthy of an artisan. Every weld on a chromoly frame must be precise, and sometimes we dwell on every millimeter of tube diameter. It's manual work, not a quick extrusion. But on the other hand, that handcrafted embroidery brings a soul that mass-produced aluminum lacks. If I wanted to go the route of lowest cost and fastest production, I'd opt for ordinary aluminum. For Dirtparade, however, entirely different values are fundamental – quality, reparability, and the soul of the bike are more important to us than chasing every gram.
Why steel? The Dirtparade Philosophy
Despite all this, steel remains – and not by chance. At Dirtparade, we have defined a vision: we want to offer bikes that have soul and perform long-term. Steel is a beautiful symbol of this. With each frame design, we change a detail to make it practical on the trails while withstanding daily stress as a loyal companion. We believe that a steel bike will last for years, perhaps decades, if the rider enjoys it and it doesn't fall victim to neglect.
Steel in our portfolio isn't just a retro piece for connoisseurs. It's also a reminder to stay authentic. Dirtparade's authenticity lies in the fact that we don't follow fashion magazine trends, but our heart. And the feel of the trails is what we want to put into every bike. That's why, even though we have lighter aluminum models and possibly carbon in the future, steel has its firm place. It's a reminder of the beginnings of BMX and dirt jumping, when every cut meant something, and every scratch on the frame told a story.
Moreover, at Dirtparade, we enjoy repairing, modeling, and modifying. If a tube breaks, we can weld it, shorten it, or add a new piece of tubing, reassemble it, and get it back in operation. That's the magic of steel – unexpected accidents don't completely negate the investment in the bike. Instead, it can be an opportunity for a new upgrade, a new shared story.
Final personal thoughts
At the end of the day, I see a bike as both a tool and a friend. That tool should have character, respond to its rider's style, be strong and reliable, but also burst with life and act a bit like a part of them. And it's precisely steel that helps me believe in all of this. I'm not saying it's always the best choice for everyone – but when someone asks me: "Steel or something more modern?", I smile and ask them: "What do you actually want to feel? How do you want the bike to react to you?" We choose accordingly.
So, on the next jump, I don't have to think about the microscopic properties of the material, but about where I'm jumping, how I'm landing, and what I'll do next. Steel gives me a feeling of confidence that even if I jump into the forest, the bike will support me, flexibly accompany my every move, and yet last a long time without betraying me. It's like an old friend who knows you love adrenaline and will always support you, even if not always perfectly.
And I think that's what makes a steel frame special for Dirtparade. It's not just metal; it's a story, a memory, simply something with a soul – just like ourselves when we hit the trail.
