Our paint jobs
Orange Green
Design: Tadek Ciechanowski
Paintwork: Dreamworkers
Design
Orange Green is our tribute to the bold aesthetics of the late 20th century. Metallic green and orange shimmer subtly, creating a striking contrast with the pastel beige base. All it takes is a closer look – the details do the work.
Execution
The design was created by Tadek Ciechanowski, a photographer and graphic designer from Wrocław, with whom we've worked for years. Tadek also took the photos of the model against a colorful background that perfectly complements the design. The metallic paints used in Orange Green contain microscopic metal flakes, which reflect light. The finish transforms completely in sunlight!
Olive Black
Design: Tadek Ciechanowski
Paintwork: Dreamworkers
Design
Olive Black was born out of a love for bikepacking. The simple form and clean transition from deep olive to black are a perfect match for a bike made for forest trails and long-distance exploration. The project was complemented by a limited series of Triglav bags designed especially for this model.
Execution
The finish is achieved by using a dedicated clear coat that contains different components than those in a full-gloss lacquer. This allows the paint to scatter light more strongly, creating the characteristic matte effect. The design was created by Tadek Ciechanowski, a photographer and graphic designer from Wrocław, with whom we've collaborated for many years. Tadek also photographed the model against a colorful background that perfectly complements the design.
Crimson Trailbrazer
Design: Dreamworkers
Paintwork: Dreamworkers
Design
Crimson Trailblazer was originally created as a demo paint job for a French YouTuber. But we liked this fiery design so much, we simply couldn't leave it as a one-off! That's why it earned its spot as one of our official limited editions.
Execution
Precise lines and rich colour depth were achieved through a professional wet paint application using water-based paints, followed by a durable clear coat, ensuring the finish remains stunning for years to come.

Geometry
The geometry of our steel bikes is much more relaxed compared to our aluminium gravel frames. A significantly taller head tube results in a higher stack and space for 700x45c tyres, making the steel Loca the most comfortable bike we've ever built.
It's perfect for bikepacking adventures and ultra-distance rides. At the same time, we kept it well-balanced – the rear triangle remains fairly short, keeping handling lively and acceleration sharp in sprints.

Steel Gravel
Rastro ST
Rastro ST is a timeless classic reimagined – built with one goal in mind: endless exploration. At its core lies a hand-brazed frame made in Wrocław from Italian Columbus Zona tubes,
paired with iconic Paragon Machine Works dropouts (Made in USA). Thanks to the fatigue resistance
of high-quality steel, this might be the last gravel bike you'll ever need.
A 21st-century adventure bike
Rastro ST is our vision of the ultimate expedition bike. A steel gravel bike designed from the ground up for bikepacking, long-distance travel, and mixed terrain riding.
Built to handle everything you plan – and more.
Steel
The premium Columbus Zona steel tubes are incredibly lightweight for steel, combining excellent stiffness with exceptional vibration-dampening
SRAM Force AXS 13s wireless
This 13-speed wireless groupset ensures a clean cockpit and flawless shifting. With a wide range and small gear gaps, it excels on climbs and fast sections alike. SRAM AXS removes the limitations of traditional mechanical drivetrains.
From 8,3 kg
Steel doesn't have to be heavy! High-quality materials, components, and thoughtful design let us achieve a weight comparable to many carbon bikes.
700x45c
The tyre clearance that meets modern standards opens up huge possibilities for tyre selection, allowing you to use the best gravel tyres available on the market.
Key features
Timeless steel
Thanks to our collaboration with Wrocław-based craftsmen, our steel frames are true works of art. We use Italian Columbus tubes with carefully selected profiles to ensure outstanding ride quality. The fillet brazing technique makes the joints nearly
invisible – just like on carbon frames.
Adventure-ready setup
Thanks to smartly integrated features, our gravel bikes are perfect for long-distance touring. Multiple mounting points for cages, racks and mudguards open the door to bikepacking and countless cycling adventures.
Ride fast. Ride comfortably.
We carefully select components based on intended use,
so every gravel bike feels right at home in the conditions it was built for.
Drivetrain built for any condition
We use innovative wireless SRAM AXS groupsets in most of our gravel builds. Why? Set it once and forget it. Flawless shifting no matter the conditions, massive gear range, long battery life, low weight, great stiffness and a clean look. What more could you ask for?
Wheels that carry you
From bombproof Mavic wheels, through boutique Dandy Horse builds, to the legendary ZIPP 303. Both in aluminium and carbon, we trust what we've been riding ourselves for years. Tyres matter too: we chose EU-made Tufo as standard but also offer iconic models from Pirelli and Gravelking – truly a class of their own!
