INNER TUBE Continental, 700c x 20 - 25 (Race 28)

Made by Continental, seamless butyl rubber, presta, 42mm removable valve core.

These tubes will easily work inside tires as big as 700c x 28 (name on the box is "Race 28" after all), but, weirdly, the box also says they're only for tires 20-25 wide.

Only 100 grams.
