Your Schwalbe tyre purchase with us is guaranteed to be genuine, brand new, and fresh-stock.

Beware of non-authorised sellers offering old or hardened rubber that may compromise performance.

Description

The Schwalbe Tube No. 7 is a high-quality butyl bicycle inner tube for compatible 20-inch tyres, available with either AV (Schrader) or SV (Presta) valve options.

Made from butyl rubber with consistent wall thickness, each Schwalbe tube is individually tested for air retention. Its broad tyre-size compatibility makes Tube No. 7 suitable for many 20-inch bicycles, including BMX, folding, kids' and compact bikes using compatible 406 or 428 tyre sizes.

Choose the valve type that matches your bicycle rim: AV (Schrader) for rims designed for the wider automotive-style valve, or SV (Presta) for rims designed for the narrower Presta valve.

Installation is available in-store at $10 per tyre.
