The Venn range is fairly comprehensive. They are road rim brake / road disc brake / gravel focused as a range. They are made to superlative standards, have an excellent finish quality to them, good, safe braking, wide internals and excellent quality control. Their profiles are progressive and stable. There is more detail about the Venn processes and manufacturing below the profile synopsis:

Venn VAR TCC – £300

Venn say:

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 profile of the Var 35 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 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 eliminate the inconvenience of having a flat tire away from home, or during a race.

DCR says:

The VAR TCC is the tubeless carbon clincher version of their 35mm profile. Carbon clincher in this instance meaning rim brake. The rim uses a massive 21mm internal profile. It weighs a pretty humble 470g and builds into exceptionally strong, durable and elegant wheels. Sets with this rim start at around £815/pair with D-light spokes and DCR hubs.

VENN VAR TCD 35mm SL – £300

DCR says:

The same profile as the TCC but a completely different layup and different resin used here. A disc specific resin is now used for maximum toughness and greatest possible comfort. The layup has been manipulated as it no longer requires such a thick braking surface – the braking surface is no longer subject to wear and requires no heat tolerance. A whopping 60g has been shaved off as a result and yet the rim can still handle enormous spoke tensions and high rider weights. If you wanted a shallowish and semi aero carbon rim – this has to be one of the very best on the market. I truly love this rim and we can build some exceptional wheels out of it. The 21mm internal also makes it suitable for narrower road tyres or gravel tyres alike.

An economical build with this rim with our centrelock hubs and D-light spokes would come to £835. A weight focused set with our lightweight centrelock hubs and CX-Rays would come to £935 and would only weigh 1380g/pair.

Venn VAR TCC 507 – £325

Coming soon

Venn VAR TCC 77 – £350

The profile of the Var 77 TCC rim was developed using the world first artificial intelligence driven process 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 Var 77 rim profile achieves excellent aerodynamics in the real world conditions where the wind comes from different directions during your ride, not in a orderly manner as seen in wind tunnels. In fact the drag of Var 77 wheels falls in presence of cross winds:

Above: transient airflow simulation of the Var 77 rim showing very good airflow attachment and minimal turbulent wake creation. The surface pressure plot additionally shows that there are no sudden pressure drops that would lead to premature separation of the airflow.

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 rims 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.
