Cheap tubes anyone tried them

It lists undiscounted retail at equivalent of $16.60/tube. Even the nicest Conti doesn't cost that much. But at $2.80/tube, it's a great bargain. It's almost worth buying to share amongst 2-3 friends.

I had the screwy bit of the presta valve of a Conti tube break off on me when i tried to pump it. I purchased the Conti tubes from Probikekit at abt $5 each.

So brand names mean little to me now ...

How much difference can there be in weight between tubes?

Unless they are going to be your race wheels, a heavier tube would mean that the tube walls are thicker, presumably this would give you better puncture protection(?). Just my thots.

$28 for 10 tubes, thats a good buy.

I understand the most consistent reason for pulled valve is due to over-tightening of the valve seat nut by the user. Some suggests to just leave it loose.
