I've been using these tubes on and off for years. They hold up well, even when patched.
Ive always gotten great performance from Conti and these tubes are no exception. I much prefer these steel schraeder valves to the plastic ones.
Bike roles way fast didn't slide on wet pavment
A good tube all around.
I used to get my tubes through Performance bike, but constantly had manufacturing defects. These Tubes just feel more quality and it gives me confidence that when I need to use my spare, it would have a flaw and fail to inflate.
I shouldn't be but these tube been lasting so far for me on every curb Jumps.
Round tubular shape. Fits inside the tire nicely and holds air as anticipated.
Product easy to install.
I bought these as spares for bikepacking. I have always been happy with Continental products.
Good tube for a good price, all good
High quality tube, good valve. Dependable at a great sale price!
Failed within 24 hours on 45mm tires. Postmortem showed failure at the nonelastic reinforcement opposite the valve. This area will not stretch when fully inflated, leaving two sharp wear points. These are probably good up to about 38mm tires.
The tire was more difficult to put on than other tires have been,
Good tube at a fair price.
I bought the tube as a back up replacement for my bike which has a 700x45 tire...I haven't used it yet, hopefully it fits ok...the quality is very good...
I love the deals I get here and the great service too. This tube works great for our bikes and is a quality product.
No flats or punctures since installation. Just wish they were available with extended valve stems.
these hold air, come at a good price and offer decent puncture resistance.
This tube is mated to Micheline Protek Urban 700c-35 and has not had a flat since installation 500 miles ago.
loses only 2-3 psi per day at 70 psi.
This tube is nicely constructed. The valve stem is beefy for city commuting.
