Continental Race 28 700x20-25c Bicycle Inner Tubes - 42mm Long PrestaValve - 4 Pack w/ Decal

I like the style of the valve. It is threaded, so the pump head holds better than it does on a smooth valve. A nut is supplied, and this nut takes the strain off of the tube when the pump head is being pushed into place. Since the core is removable, it is possible to add a sealant to the tube ... Stan's, for example. That having been said, my experience suggests that Stan's does not always seal at such high pressures (110 psi). I quit adding sealant, but I still like the tube.

I've used Continental branded tubes and tires for several years and have never experienced a problem with them. Great durability at a decent price.

Continental tubes are the best. I have used them for as long as I remember. Not the cheapest but no flats either which is worth the money.

I have been using Continental Race 28 Gatorskins on my bikes for the past 4 years. The quality is excellent, and I get about 2,000+ miles out of a set. The price was very good.

Contitubes have been my go-to for a long time. I spent a few years living in southern Italy where to roads are brutal on a bike. I found these tubes then and found they are much more durable and with much higher quality control than cheaper tubes. I haven't bought any other brand in years because these are just that good.

I went through all five of these inter tubes in about a week. Each of these blew out within 6-9 miles on the road. A local bike shop indicated that there's been a "bad" batch of these and several bike riders had the same issues. It wasn't glass or road trash or over-inflation, it was a poor product. I won't buy these on-line again.

These get holes and leak, but so do all bike tires. These were a decent price.

Exactly as described and traditional Conti quality. I did not receive the decal but that was / is of no importance to me.
