2-Pack Bike Tubes Apply to 700x18/23/25/28/30/32c,Lightweight Road Bike Inner Tubes with 60mm Valve,Durable Bike Tire Tubes for Mountain Bike,Plus 8pcs TPU Gluefree Tire Patch.

I got thees to use as spares for my road bike, where I run a tubeless setup. I carry them instead of butyl tubes because they are much lighter. I had a Pirelli TPU tube and had to use it once. It worked great, but I damaged (by rolling over it with some wheels while on the garage floor) when converting back to tubeless. I didn't want to spend the $35 that they charge for the name-brand tube, and I also didn't like the all-plastic valve stem. So, I decided to give these a try. I haven't actually used it yet, but it seems well made and very similar to the name-brand. One difference, that I like but that will make it heavier, is that the valve-stem is metal.

Huge weight savings over standard tubes, road most of a season with out any punctures and minimal normal pressure loss. Granted the comfortable ride is also due to wider road tires and overall wheel setup but the tubes appear to provide that extra bit of comfort. Highly recommend these tubes. Oh yeah, the smaller size is nice for storing the spare tube.

I am an experienced cyclist and avid rider (average 1,000 miles monthly). I was pretty excited to try these tubes after being disappointed in the Turbolito Tubes (see my review). However in just two 30 mile rides I had a total of 13 punctures and a massive loss of air that almost resulted in me laying the bike over in multi-lane traffic. I have ridden for months on regular tubes with only 1 or 2 flats on the same route.The Good:- Cool Green Color- Metal Valve Stems- Great plastic Band to keep the tube tidy as a spare....and you'll need it!- PATCH KIT is great in that you get a bunch....but you'll need about 10x what they provide- Ultra light, but whatever time gain you get is blown on replacing tubest every 50-60 miles- Terrific and easy install - no tire levers neededThe Bad- Absolutely UNSAFE....the slightest intrusion and you will have punctures- Any weight savings is blow as a result of having to carry multiple tubes- Massive air loss possible due to road damage resulting in possible loss of control- Even with proper cleaning and cure time some patches will not adhere to the TPU. I purchased a separate TPU patch kit which performed much betterSummary - if you are using some super tough tires (Gatorskins, etc.) or on an indoor/groomed track without risk of debris/damage, these would/may be amazing. For real world conditions STAY AWAY if you value your bike and/or life.See photos - these were patches after on TWO 30 mile rides! Insane.

On my bike 6 months now, many miles on Ohio roads, work great no issues no flats I’ll be buying more.

The good: Very lightweight, good ride quality. They feel as if rolling resistance is less than normal butyl tubes, but by how much I don't know. I do know they are fast in my 40mm carbon wheels with Conti 5000s, 28mm.The bad: despite using the provided cleaning pads and patches, my experience was the repairs don't last. In two cases I repaired a puncture, patch held for a bit, then a leak developed mid ride from repaired area. At the price these are, one puncture and done is a little steep for my taste.

I weigh all the bicycle parts i get and this one waswithin 1 gram of advertised weight. Put it in the tire and have done maybe 100miles without any problem. I keep a spare in the pocket and it's nice it takes so little space.

The value leaked and tore after a rides

I've put about 1k miles on the vittoria latex and didn't have any issues, but wanted to try something lighter. Swapped them out with these green TPU tubes and was noticably lighter in weight. The feedback from the tubes are small and maybe too indifferent for me to notice.The installation was trickier than usual because they were so slippery. Remember to read the included instructions and warnings. No air compressors, don't inflate more than 8psi while installing.The green ones also hold air better over a few days than the latex tubes.

Ich fahre die Schläuche seit letztem Jahr im Rennrad. Seitdem sind mehr als 700km vergangen ohne Probleme. Besser als die von Pirelli.

Die Produkte ist eigentlich dick und günstig als in der Laden
