Continental Race 28" 700x18-25c Bicycle Inner Tubes - 42mm Long Presta Valve - 4 Pack

These tubes compared to my previous ones are amazingly thick. That provides some comfort when riding at fast speeds downhill on a main street with cars in close proximity.

Came quickly, and good price.

Exactly what I was looking for and as described

it does what is say it is

Kept getting flats so i started looking for bulk tubes. Eventually i realized i kept getting flats not because of goat-heads, thorns, etc., but because many of the tubes themselves were defective. I kept getting tiny holes in the exact same place: opposite the valve steam. Checked the inside of the tire repeatedly, the rim, etc., but nothing there. Just manufacturing defects i have to assume. I've had a few that worked well, but at least half (after buying at least two four-packs) have not worked. Bummer.
