Product details
Description
The Hartex Compact inner tube fits 20-inch tyres in the 20x1.75 to 20x2.25 range, with ETRTO compatibility 47/57-406. Its butyl construction is a practical everyday choice for children’s bikes, BMX-style bikes and compact utility wheels using this rim diameter.
Check the tyre sidewall for the 406 mm bead-seat diameter and a width between 47 and 57 mm before fitting. The rim must also be drilled for a Schrader valve, and the 48 mm valve length should suit most standard-depth rims.
