The profile of the Var 45 TCC 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 resulting aerodynamic performance exceeds that of generic 50mm+ rim based wheels in some conditions while offering superior handling.
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.
VAR filament winding process utilises slit tape towpreg to accurately lay up the carbon fiber in an automated, computer controlled process.
The use of preimpregnated carbon fiber tape allows us to use the latest resins that offer the optimal blend of high glass transition (Tg) temperature exceeding 240° C in testing , toughness and impact resistance. Var rims can therefore be used in challenging conditions where extended braking periods are expected.
The wheels are compatible with clincher, or tubeless tires that when used with a sealant virtually eliminate the inconvenience of having a flat tire away from home, or during a race.
Venn Rea db hubs feature a cold forged, CNC machine hub shell with a low drag 24 pawl engagement freehub rolling on Enduro bearings that feature dual lip seals to keep the water and dirt out, and grease in ensuring better performance even in bad weather.

I went from Giant’s SLR1 carbon clinchers to this wheelset and it has been quite a noticeable improvement! There was some initial hesitation in putting on a slightly heavier wheelset but there are definitely have not been any drawbacks. It’s been improvements all around: power transfer and acceleration feels improved- wheelset feels stiffer, holds speed better (more aero?), “feels” like rolling resistance has been reduced, does not feel heavier on climbs, brakes better, improvement in comfort (went from 17mm internally wide rims to 21mm), and the most crazy part that I don’t get is even the handling of the bike feels sharper yet more stable at the same time?

Used RaceRim built Reynolds OEM 50mm with White Industries hubs attached by Sapim CX-RAY bladed spokes. Always Continental GP400S IIs, butyl tubes and Velox cotton rim tape. The tried and true no flat combo. No issues other than cross winds. Always wanted Venn rims for my Magnus and finally was able to get some. #1, braking performance stomps the Reynolds setup. No noise, superior braking in all conditions. #2, no difference in rolling, same setup of tape, tires and tubes. #3, slightly more road feel in the Venn rims and better stability in fast downhills. #4, better handling in crosswinds. Summery, a good purchase with no real loss and increased performance in stability and braking.
