More stiff and aero than the Katana. The Ceepo Viper remains in our line up for the athletes that prefer the conventional frameset design over the beam design.

The Viper is race proven with rim brakes. The Viper is stable, stiff, and fast. With no special calipers or parts needed it remains easy to travel and maintain. To this day, the Ceepo Viper adds victories all over the world.

Truncated Airfoil Tubes:

Stiffer, lighter aero tubes.


Lowered BB:
For improved high-speed stability and better overall aerodynamics BB EVO386.


Internal Di2 Battery Adaptor:

Accessible battery location in the lower section of the downtube.

Reversible Seat Post:

For a wide range of saddle adjustability. 


Direct-Mount front and rear for superior braking power along with easy maintenance. 

By hiding the rear caliper behind a lowered down tube section; we can achieve both speed and simplicity of adjustment as well as easy maintenance making the life of the traveling athlete more enjoyable.

Assembly Guide




Long front center

Most tri bikes front center incorporate road bike dimensions …we design our tri frames with a 20 to 25 mmm longer front center to add stability while keeping handling as normal as possible.


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.


Flat top tube

The top tube is flat to help torsional stiffness of the headtube area and allows better integration of a bento box.
