At 32 g, the Eclipse Performance Brompton tube is one of the lightest inner tubes made for any wheel size designed specifically for the 16 1" (ETRTO 349) tyre standard that Brompton uses across its entire range, and includes the valve hole adapter that the Brompton's narrow fork crown requires. Why it works 32 g. 70% less than a standard butyl Brompton tube .
