Scorpion Venom and Attack rims are selected rims developed in Germany and designed using extensive applied and theoretical aerodynamics know-how acquired during many years of work in wind tunnels, and at the cutting edge of computational fluid dynamics (CFD)
Every rim undergoes tire inflation test, dimensional accuracy testing, and batch testing using X-ray imaging to identify any potential lamination issues before the rims are released for sale. Venn standards are among the highest in the industry
Patented filament winding process ensures precise and accurate carbon fiber layup – each fiber is oriented exactly as intended. This ensures that every rim achieves maximal strength and durability
The rim shapes are formed using metal mandrels, not bladders or foam. Metal mandrels deliver much higher tolerance and molding accuracy, and prevent fiber migration during curing
Complex post cures process to completely finish the epoxy resin reactions. Resins used in manufacture of sporting goods (rims, frames, rackets, etc.) often do not in fact fully cure until several days after the initial curing (baking) cycle is completed. Two additional post-cure cycles for additional 14 hours is also performed. This results in the rims being fully cured and therefore entirely stable once you start using them
The filament winding process utilizes slit tape towpreg to accurately lay up the carbon fiber in an automated, computer controlled process.
The profile of the SLD45 rim was developed to offer the best aerodynamics when used with 25-28mm tires. The external width of 30mm optimizes the airflow in combination with wider tires, while the internal width of 21mm ensures that the wider tires achieve a stable, round profile. The rim width also means that the rims are laterally very stiff while the filament winding process ensures that the rims remain vertically compliant due to the 45 degree fiber layup bias. The combination of these features results in very fast, safe handling wheels that can be used in any conditions.
The wheels are compatible with clincher, or tubeless tires that when used with a sealant virtually eliminates the inconvenience of having a flat tire away from home, or during a race.
