Mizuiro Blue
Midnight Stealth
Light, Fast & Easy to travel with
When we designed the Katana, our goal was to achieve the simplest, fastest, easiest to travel with triathlon bike. It continues to be the best selling Ceepo model every year. There are no special brakes or parts required. The Katana frame can be assembled by any mechanic and at 1195g Raw M size, Katana is one of the lightest Long distance triathlon frames available. It is very stable and fast in crosswinds; the Katana’s geometry allows for an aggressive forward positioning and is the perfect frame for the athlete that like a traditional, simple, double-triangle frameset!

Katana
Mid to long-course performer
The Katana is named after the Japanese short sword 刀 or かたな developed over centuries is a source of inspiration, not only in name but form and function: a quick handling weapon due to its elegant curved, slender, single-edged blade. Regarded as both a devastating weapon and work of art, the Katana is light, practical and effective.
The Katana hits the sweet spot for Ceepo, combining efficiency, stability and capability in a well-crafted aerodynamic solution for triathlon racing.
Versatile Race Machine: The Katana is a bike for every occasion, efficient on a variety of courses across all event distances - sprint, half and full ironman distances. More importantly, the Katana can go fast regardless of the terrain. Hilly, windy, straight or flat. The Katana does it all.
The Katana is a stable, fast accelerating platform. There is a reason so many of Ceepo’s athletes choose this weapon for all their endeavors.
Aero: NACA 0021 truncated airfoil tube shapes at the downtube, fork and seat stay combines with a traditional double triangle frame in order to enhance aerodynamic proficiency.
Personalized Geometry: The long and low geometry allows riders aggressive forwards position to minimize turbulence and optimize slipstream positioning, comfort and speed.
Customize: Add to this a headset and front end that is endlessly customizable allowing for industry wide aerobar compatibility, from off the shelf to 3D printed customized set ups. The reversible saddle also enhances rider specific fit.
Simple Assembly and Travel: And yet, as a bike designed for the demands of elite level racing, the Shadow is easily disassembled and assembled for transportation to and from destination events.
Weight: The Katana is a lean machine too, with a Medium frameset coming in at only 1195g (Naked)
Aero Tubes
Elegant aero tube shapes take advantage of truncated airfoils which allow the Ceepo to seamlessly combine greater aerodynamics to reduce drag and headwind turbulence while retaining competitive stiffness and weight values.
Easy access to cables,
battery connectors
You can access cables, connectors, and battery on all Ceepo frames without removing BB or other parts. You will not require a skilled mechanic to travel.
Low downtube
aero: A lowered downtube has a shorter leading edge exposed to the wind.
stiffness: Hiding the downtube behind the fork crown allows us to design a wider, stiffer tube section in this critical headtube area without an aero penalty.
Saddle System
Wide Range Seatpost (WRS) a reversible aero seat post that emphasizes fit customization and generous fore and aft adjustability across aero road and triathlon bikes. Carbon creates a comfortable contact point for reduced fatigue and vibration management. For gravel, carbon for comfort and vibration dampening; a 27.2 diameter for industry wide seat post preference and dropper post compatibility. Make the bike fit the rider.
One-Piece Fork
Integrates with the frame to create a single contiguous profile improving airflow. Flattened wide legs reduce form factors, narrow towards the axle for stability; reducing drag and turbulence, especially in headwind conditions; provide precision handling with a balanced weight to stiffness ratio. The crown tail further smooths airflow over the bike.
Geo
Aggressive, responsive, stiff and stable. Long and low triathlon geometry allows for streamlined comfortable positioning to amplify power, efficiency and acceleration; aero road bikes inherit neutral road handling from classic road bikes to create a well-mannered, confident, and predictable experience, at speed on flats or descents, but also allowing for an agile climbing experience. Gravel geometry retains the signature features of the aero road bike line, but shortens the rear stays and raises the front end, creating more stability and comfort to reduce fatigue over the distance and across a variety of unpredictable terrain.
