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.
