Scorpion Technologies
SCORPION CARBON RIMS ARE MANUFACTURED USING A UNIDIRECTIONAL AUTO FILAMENT WINDING PROCESS BY A ROBOT, THAT PRODUCES THE STIFFEST AND MOST DURABLE LAMINATE RIM IN THE WORLD. IT IS OUR LAMINATE DESIGN, ALONG WITH OUR NEW PATENTED HIGH TEMPERATURE RESIN, THAT MAKE SCORPION RIMS THE MOST TECHNOLOGICALLY ADVANCED ON THE MARKET.
Hand crafted in USA
Tested in lab and in the real word by bike fanatics
"Stinging the competition one wheel at a time"
Auto Filament Winding Technology (AFW) has changed the way carbon rims are produced. Different than producing the rims by hand, Filament Winding is done by Robot, which is Pre-Coding with program, so human error is removed from the equation.
We are confident that you will be satisfied with the performance and value of our products, or your money back.
We back our products with 2 full year warranty, and offer a discounted parts only charge on crash replacement.

Scorpion Venom Series Carbon Rims Test Data
Venom CR50 Carbon Rim
Venom - Carbon Rim Technology:
Carbon from Toray T800 and Mitsubishi Rayon in Japan,
the world’s largest producer of carbon fiber
– Used by the aeronautical and defense industries.
- Braking surface up to 240c deg.
- Composite, CNT (Carbon Nano Technology)
- 50-200 gpa (100 times of steel)
- EPS (Expanded Polystyrene System) keeps the inside smooth by melting away in the casting process.

Carbon wheel rim brake test
Rim test failure at 20 mph with same brake pressure applied until rim explodes
(this is the reason why Big wheel companies are pressuring Big bike companies to go with disc brakes)
In the test bellow shows the time in seconds and temperature F of the rim before ploding
Notice that some rims got hotter as the time before failure went down.
We can assume that, more friction = better braking = more heat = quicker failure
Carbon is a non conductive material so, heat builds up. This is a problem because heat will not transfer throughout the entire rim surface but, it will remain on the applied area of friction, brake track. As the resin gets soft with the heat, the pressure from the tire forces the rim outward. Once the tire bid passes the edge of the rim, the tube explodes destroying everything on it's way.
Roval Wheels were the worst in this test, ouch. (pic #4)

How did we fair with our Scorpion Venom series rim?
Scorpion Venom rim survived this test after 1200s / 264 F, and it cooled down from 120F to 0F in just 34s compared to 393s for Zipp 404

Look closely at the filament layup. Scorpion Venom Series rim, it's made using the same auto carbon filament wrapping technology as these famous brands Enve - Alto - Giant - Ursus-Venn |

The carbon fiber clincher may very well be the perfect wheel: it’s fast, light, and strong, with the added benefit of convenient-to-change tires. They are some of the hottest products in cycling today. There has been a flood of new carbon clinchers into the market, with vastly differing levels of quality. Our carbon rims utilize advanced technologies ACFW (auto carbon filament wrapping) and our own patented heat resistant resin in the production that allows them to safely withstand the extreme heat (240c) and force created under different cycling condition, even the hard and long braking without any heat failure.
AFW - Auto Filament Wrapping
The carbon filament comes in a spool and goes through the resin tank as it gets wrapped around a mold to form the rim. This creates a uniform rim without seams or deformation. The patented high temp resin is applied in the process.
A computer controlled robot controls the entire operation, assuring precision and uniformity.
NO HUMAN ERROR IN THE PROCESS

-Smooth interior wall
-Alloy belt, to reinforce nipple contact
With our wrapping system and EPS used by other big names like Giant, ENVE the interior of the rim stays smooth. EPS its like a foam material that melts away after process.
Other rims use bladder system that will wrinkle and cause a uneven surface on the inside, and that in turn causes uneven weight distribution.
To Reinforce spoke nipple contact and spoke tension we added an Alloy belt.
Baking process:
One time high temp molding and two times high temp baking

Venom CR50 rim test
We have the test machine in the factory to test the rims/wheels, the machine works by spinning a wheel using a chain and simulated rider load and then applying braking force while measuring temperature at multiple points hundreds of times a second using laser technology. The machine can also precisely measure wheel and tire width and see how these dimensions change as braking is applied and heat is generated.
Toray Carbon Fiber - Many small factories, they only purchase the finished carbon fiber, so they don't have much control of resin application. We have the carbon weaving machine in house to make the carbon material to our specs. Further more, our factory purchase the carbon filament
T 700-T800-T1000 from Toray Japan and Mitsubishi Ryon used in aeronautical and defense industries, helping us develop the best rim quality possible and cutting costs by producing it in house.

Auto Filament Wind -
Our engineers developed an automatic wrapping machine to shape the rim bed, so each carbon fiber layer can be evenly distributed and tightly bonded, enabling its strength to reach a maximum value and uniformity. Other wheel manufactures purchase the carbon in sheets, pre-peg, and they cut it and lay it over a mold.If you look up close the rim you can see the seams.

Scorpion Alloy Rims
We have two types of alloy rims
1) Our special developed tubeless ready rim CX26 is an all round performer used for most ride conditions.
Whether you go on road cross or gravel this rim at 470g is strong with extra material at the nipple edge so it can withstand higher spoke tensions and light enough to make a every day wheel of choice.
CX26 wheelset with 20/24 spokes weights in at 1500g. About the same as any big brand $900 wheel set.
2) For the more selected rider/racer we have SLR series rim made with, Super light Niobium alloy .
Niobium alloy is a proprietary material which has been developed by our rim supplier. Niobium alloy uses an advanced T10 heat-treatment process and delivers outstanding weight, stiffness and durability meaning rims can be wider for 25 and 28mm tires, deeper for better aero performance and yet remain super-light for excellent climbing and acceleration.
SLR series tubeless rims 24x22mm 440g / 24x31mm 480g.
