Description

A Schwalbe SV7S inner tube for 20 inch wheels running narrow rubber, sized 20 x 1-1/8 to 1-3/8 inch. That is ETRTO 28/37-438/451 mm, so check your tyre sidewall against those numbers before you order.

It uses a Presta valve with a 40mm stem, and it is the standard version rather than a lightweight or reinforced one. Weight is 105 grams.

Features
  • Presta valve fitting. Suits rims drilled for the narrower Presta valve, which is common on 451 and 438 sized wheels.
  • 40mm valve stem. Long enough for standard depth rims, so you can still get a pump head on cleanly.
  • Fits 20 x 1-1/8 to 1-3/8. Covers a range of narrow 20 inch tyres, so one tube spans a few different setups.
  • ETRTO 28/37-438/451 mm. Check that code on your tyre sidewall and you will know straight away whether this tube is the right one.
  • 105 grams each. The standard version, so you get everyday durability rather than a stripped down race weight.
