Newmen has developed this inner tube with Tubolito for use with all STREEM VONOA wheels.
It is for use with the internal STREEM Aero valve system, where the valve is hidden for aerodynamic benefits.  

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
At just 40 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!

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.
