## Description

International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.

Review: Great Tubes - These are a great tube. Heavy duty yet still feel comparable in weight to a lesser thickness tube. They hold air pressure longer and I have also noticed next to no flats from small punctures. These will be almost bullet proof with some sealant added to them. I will definitely continue to buy these as needed in the future.
Review: quick service - Good timing and the tube is doing very well.
