Venn 2539 THL UL 300g ultra light tubeless hookless asymmetric carbon rim for gravel and XC racing

Venn 2539 THL UL is an ultra light (300g) 29″ gravel and XC race bike specific tubeless, hookless asymmetric carbon rim.

Its wide and shallow profile delivers exceptional handling and comfort, and allows optimal fit of wider tires. The layup was additionally optimised for light weight and greater compliance which further improves both comfort and the ability of the wheels to remain in contact with the ground.

The 4th generation 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 toughness and impact resistance.

CTL SL hand layup carefully positions the carbon fiber reinforcements only where needed

By reinforcing only the key sections of the rim we are able to manufacture very reliable but also very lightweight carbon rims.

The Venn 2539 THL UL asymmetric 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.

Hookless design substantially increases the rim impact toughness. We can assemble your set of carbon wheels using hubs of your choice.
