Filament wound full carbon tubeless, or clincher rim for gravel bikes and wide tires, 40mm profile. Disc brake.
The Venn Var 40 TCD wide disc brake 40mm gravel carbon rim is aerodynamically optimised for wide tire use. The objective was to deliver a rim that is aerodynamic at large yaw angles.
Riding a bike over uneven terrain means that it is impossible to hold the wheel straight. It bounces, moves, you correct your direction to pick the best line, but you do not want to slow down. This means that your front wheel will not spend much time facing the direction that you intend to travel. The Venn Var 40 TCD carbon rim was developed to make you go faster in real gravel conditions, not in a tunnel. The rim’s spoke hole strength is 100% higher compared to other carbon rims in the market. This ensures that you can use your wheels in any condition without fear of damage.
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 toughness and impact resistance. Var rims can therefore be used in challenging conditions where extra toughness is of great benefit.
The Venn Var 40 TCD 40mm gravel carbon rim is 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.
We can assemble your set of carbon wheels using hubs of your choice.
FAQ
It is internally wider (23mm vs 21mm) which better supports wider tires. This ensures that a relatively wide tire (for example a 28mm tire) obtains a more aerodynamic shape, and that it is more stable on the rim so that it rolls less when cornering at higher speeds.
Yes, it is strong and durable enough for XC use, while the slightly rounded and sloped rim sides protect it from most of the rock damage. However, the main advantage of this rim over standard MTB rims is its superior aerodynamics when used with tires 28-30mm wide.

I had bought several other gravel rims for my bike but I wasn’t satisfied with the results I got. I was lucky to come across Venn cycling in a forum post, and I decided to purchase this set of rims because they have a mid 40mm profile, which was what I was looking for. The Venn Var 40 TCD hasn’t disappointed in any way. I’m surprised at how smoothly I can ride on gravel. The product arrived faster than I expected, well-packaged. Happy with my purchase!

I really wonder the kind of technology used to make this 40mm gravel rim, but I’m happy it is very durable and stable on rough gravel terrain. I don’t get to struggle with my bike anymore like I used to with my original set that came with my bike. This is a great upgrade and it will transform your bike. Thank You!

For the price, I will say this Venn Var 40 TCD is the best gravel rim that I have had on my bike. Unlike other carbon rims I bought in the past, I hardly noticed moving from road on gravel terrain in terms of handling. Plus, the customer service has highly responsive in providing answers to my inquiries. Highly recommended!

I normally don’t leave reviews, but when support and service are as good as mine was with Venn customer support, I wanted to make sure and recognize a good experience. The 40 TCD I bought has been amazing because it is reasonably light, durable, and study on gravel. I also like that these carbon rims are compatible with all tubeless tires due to the hook so I am not nervous about blowouts.

I received my Var 40 disk brake carbon rim faster than I was told, so that alone is a big plus. I’ve only been on them for 150 miles, but I can honestly say I can tell an immediate difference in the responsiveness of the carbon rim. They are perfectly fine for wide 40mm tires as stated on the website. Quality is a 10/10.
