The Impac AV24 inner tube is made for 24-inch tyres using the 507 mm bead-seat diameter, with ETRTO compatibility from 40 to 60 mm in width. It is a straightforward butyl tube for everyday 24-inch bikes that use a Schrader valve.
Before fitting, check the tyre sidewall for an ETRTO marking ending in 507 and a width within the 40/60 mm range. Because 24-inch tyres exist in more than one rim diameter, the ETRTO number is the safest compatibility check.
