Continental ContiTech Inner Tube

This tube is designed for 20-inch wheels with an ISO diameter of 406. Please check the sidewall of your current tire to ensure it matches the 406 ETRTO standard, as some 20-inch tires use different sizing.

Yes, the removable valve core makes it easy to inject tire sealant directly into the tube, which is a great way to add extra flat protection for your ride.

A 42mm valve length is standard for most 20-inch rims. If your rim has a deep-section profile, you may need a valve extender, but for standard alloy rims, this length provides plenty of clearance for your pump head.

Mold-cured construction creates a seamless tube with uniform wall thickness. This consistency helps prevent weak spots, leading to better air retention and a more reliable ride compared to cheaper, seamed alternatives.

Yes, you can use any standard floor pump equipped with a Presta-compatible head. The threaded stem also ensures a secure grip for the pump head, reducing the chance of it slipping off while you inflate.
