I've got these tubes (off the bay also, but without the patches, humph.)

Mine weighed in at 78 and 80 Grams and are nicely pumped up to 45 Psi in a 2.1 Conti Speed King Supersonic, seem to be hodling air very well.

Saved a massive 102 grams.. Nice.

Digital kitchen scales ?
Sound like them, measure in 2g steps so sound like they are 79 g one just over, one just under. 158g together would narrow down the range of the 2g margin. You need a more precise balance. :twisted:

Yep digital kitchen scales but they measure in 1g increments, just slight differences in tube manufacture to account for the weight diff betwixt the two.

Tintin: cheers for park patches link
