Venn 37 TCD Disc


Venn Var 37mm Tubeless Carbon Disc filament wound disc brake carbon rims. 

This rim is well suited to the all-rounder road cyclist, good for climbing but with an aero benefit.

Please note the rims are supplied with no decals. Image for illustration purposes only.

Weight: 440g

ERD: 570


Venn rims are 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 tyre 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 fibre 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 fibre migration during curing

Complex post cure 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. Venn therefore perform two additional post-cure cycles for additional 14 hours. This results in the rims being fully cured, and therefore entirely stable once you start using them

VAR filament winding process utilises slit tape towpreg to accurately lay up the carbon fibre in an automated, computer controlled process.

The wheels are compatible with clincher, or tubeless tyres that when used with a sealant virtually eliminate the inconvenience of having a flat tyre away from home, or during a race.
