ContinentalCompact 20 Inch Presta Tube(Return to Product Page)

One of the two tubes I purchased blew out before riding 25 miles. It had a 3/8 inch slit in the tread area. No problem with the tire. The other one has been going fine after a couple hundred miles.

Nice durable tube. Was a bit large for my Panaracer 1 1/8 x 451 tires but the quality is there.

Tubes for my ice trike. Reliable and durable tube.

There's not much to say. It's a presta valve tube. I ordered 2 for the front of my trike. I've always had good luck with Conti products.

I like these tubes because they fit either my 406 or my 451 tires, and I have both sizes on two of my bikes. The price is reasonable and they seem as durable as any other tubes I get.

Need a quick replacement for 20 406 recumbent front wheel. Ordered 2 tubes and arrived very quickly. I was back on the road in just a few days. Now I know where to go when I need something quick.

Excellent quality and excellent fit. Highly recommended.

I love the steel Schrader valve it makes filling the tube so much easier and the nut on the valve holds it in place

Good price for great product

Hard to say much about a tube.

They hold air well.

Have not had a flats while using them.

I like that they have a metal valve tube with a lock nut to hold it in place.

Needed some spares for this smaller wheel size and wanted something lighter more competitive than the ones shipped with the recumbent. These fit the bill! No problems with them, been reliable and happy with weight cost. Will definitely get more over time as these aren't something a smaller LBS will have in stock (found out hard way). So, one in bag for the unexpected flat and in wheels - happy as I can be.

Never a problem with these. They allow me a lot of untroubled miles.

Good product, reasonable price

So far so good in the rear wheel of my Dahon D7

I like the Continental steel stems.

Both tube went bad within 2 weeks. One the first day. Had 45 pounds of air in it but it still split out at the seam after a very short ride. Checked the inside of the rim but couldn't find any reason for it to blow. weeks later while riding the rear tube also blew out. Again couldn't find any internal problems but again it was along the seam of the tube. Went to Wal Mat and bought one from their supplies. Both are still holding up fine now with the 6 year old rider on it. Was a little disappointed with the quality of the tubes. George

I nevet havr any trouble with these tubes on my recumbents. Roll smoothly and don't have that slow air loss some tubes have when in the garage over night or for a few days

Great tube for my recumbent. This tube is made for an adult bike and not a kids or BMX bike. The all metal stem is far more durable than the rubber covered version. Tube has a nice thick wall.

I run these on my zox low racer.

I always buy new tubes with new tires, so these were installed with a new set of Conti 20 grandprix tires on my Zox lowracer. So far not flats and the tubes fit the tire size well. Not all 20 tubes fit well
