NEWMEN-Tubolito Road and Gravel tubes
Newmen has developed these inner tubes with Tubolito for use with all STREEM VONOA wheels.
They are for use with the internal STREEM Aero valve system, where the valve is hidden for aerodynamic benefits both on the road or gravel.  

NEWMEN Streem Aero
The revolutionary NEWMEN Streem Aero system hides the valve completely in the rim and ensures better aerodynamics and a clean look.

TUBOLITO Tubo-Road-NEWMEN
At just 42 grams, Tubo Road offers up to 70 % weight savings compared to a standard inner tube. In a race, this can be decisive when valuable seconds are at stake. Tubolito combines a new high-tech material with a specially developed seamless production technology. Tubolito Light Weight tubes can withstand up to twice the force of standard tubes. They are also twice as elastic, durable, UV-resistant and retain air for a very long time, guaranteeing you maximum drop-out protection. The Tubo Road tube is suitable for disc and rim brake wheels. How much pressure can be pumped into Tubolitos depends on the tire used. Therefore, please observe and comply with the information on the casing. However, it is important to note that Tubolitos should not be inflated to more than 0.5 bar 7 psi outside the tire, otherwise they will deform and become defective!
 
TUBOLITO Tubo-Gravel-NEWMEN
Gravel roads, cyclocross circuits, and everything in between — the Tubo-Gravel is designed to handle it all.
At 62g it is up to 60% lighter and twice as tough as standard tubes, it improves rolling efficiency and saves precious grams without sacrificing reliability. Compatible with both 700C and 650B tires, and fully resistant to tubeless sealant residues, it’s the smart choice for fast, flexible, and fearless riding.
 
TPU – high-tech material for the highest demands
All Tubolitos are made from the high-tech plastic TPU. TPU has been successfully used in the industry for many years and is valued for its outstanding performance. The founders of Tubolito, Ákos Kertész and Christian Lembacher, worked with TPU before founding Tubolito and have built extensive expertise over the years. The combination of TPU with a patented manufacturing process makes it possible for Tubolitos to be small, lightweight, and at the same time puncture-resistant. These properties can be optimized depending on what is required from the Tubolito.

Note: Together with the adapter supplied in the Streem Aero Valve Kit (57579), which comes with the wheels, the tube can be used and inflated just like the Aero-Valve system would be if set up tubeless.
