This latex tube is especially making vor Ginkgo. This is a 100% latex tubes and not a latex tube of any other tube-manufactor, which make a combination of butyl and latex.
It guarantees low rolling resistance and is very light. The best preconditions for racing or record rive.
Valve: SV (Sclaverand) 51 mm
Weight: 48 gr.
Please note that latex should not be exposed to sunlight for long periods of time. Keep replacement tubing in opaque containers. Pure latex hoses in particular age quickly under direct sunlight and become brittle.
Working fantastic for me.
