(RE)introducing the Viper
Viper: JUST AERO
The Viper is the original iconic CEEPO triathlon platform, ahead of its time, designed against convention to bring cutting edge performance to the race course. The original Viper trashed the rulebook on triathlon bike design to explore how far carbon tubes could be shaped to obtain performance centered aerodynamic advantage. In doing so, the original Viper created its own "against the grain" tradition, guided by out of the box thinking to make fast bikes slip through the wind.
​
Viper 2.0.
The next generation 2023 Viper is a faster, sleeker and more aerodynamic celebration of our 20-year pursuit of unbridled performance. The Viper is our work horse aero specialist, drawing on the unique heritage of the original Viper while combining lessons learned from the Shadow R and Katana to speed athletes from the water to the run to the podium.
Vision:
The 2023 Viper doesn’t overcomplicate things, but makes its statement through subtlety and attention to detail. And this is what set’s Viper apart: a frame design that is dramatically streamlined, yet packs a serious punch. Elegant, understated, yet aerodynamic and explosive. A fuss free powerhouse that will take care of the bike split, so that you can take care of the rest.
Just aero. Just fast. Nothing else.
All the Aero in One.
The Viper distills 20 years of expertise into a minimalist, aero optimized race bike that doubles down on the key components for going fast: geometry, carbon quality, weight and aerodynamics. This less is more approach fine tunes tube shape design so that carbon is placed where it matters most while eliminating unnecessary material that could weight the bike down. If it doesn’t make you faster, it’s not on the Viper.
Less isn't just more; less is faster.
​
Performance:
Viper is a well-rounded mid to long course specialist, fast on the flats, agile, efficient on climbs and undaunted by headwind turbulence and crosswinds; comfortable and well-mannered when riders are in the extensions or rocking out of the saddle; quick to accelerate at the best of times; stable through unpredictable road and weather conditions at the worst of times.
Perfect even when the day isn’t.
Features:
Viper balances weight and stiffness with an aerodynamic chassis that amplifies pedal input. Truncated airfoil tube profiles are strategically yet economically used where it matters, from the downtube to the stays, seat and head tube and fork blades. Increased trail values offer stability and handling at speed. The top tube tapers, shedding weight as it narrows towards the seat tube. A reversible carbon seat post offers fit customization while dampening road chatter. No more cables. Full cable pathway integration reduces headwind turbulence, concealing cables and hoses out of sight, out of mind and out of the wind. Lowered seat stays reduce drag force while CEEPO Aero Brake Technology conceals the brake calipers and enhances airflow across the bike. Top tube mounts provide onboard storage when needed. Tire width versatility provides up to 28mm tires.

Cable Integration
A premium integrated aero aesthetic
If wind resistance is a triathlete's greatest adversary, the Viper is the triathlete's greatest ally. The Viper minimizes frontal surface area by completely concealing the cable and hoses out of sight, out of mind and out of the wind. Doing so creates a clean front end that reduces headwind turbulence and overall drag. So, yeah, basically more aero. Cable free also means there is nothing to interfere with aerobar hydration set up. Most importantly, it just looks great.

Aero Brake Technology
Unique to the Viper, ABT conceals each brake caliper behind a carbon shield, effectively hiding each brake caliper from the wind while enhancing airflow at these key points. As part of a system, ABT creates a unified surface allowing the air to flow efficiently and smoothly over the front end, across the Kammtail downtube and rearward reducing the low-pressure wake. Combined with the cable free cockpit, the total aerodynamics of the Viper enable a comprehensive surface area that reduces drag across the entire bike. Lowered seat stays further reduce drag force while providing stable support, especially when athletes are putting down the power in the long and low forward position.
