Ich bin extrem zufrieden mit diesen Schläuchen.

I bought these for packing as spares for an emergency. Their small size makes them easy to fit in tight spaces. I installed one pair on my bike and they seem to perform well and seem to hold air well. Be aware to order the correct valve stem length as extenders do not work with these tubes due to plastic valve stem construction. This has not been an issue so far.

La calidad es muy buena

チューブの継ぎ目からエアが漏れる個体があるようです。三本買って二本がダメでした。

These are my new emergency repair tubes for my road bike running 32mm wide tubeless tyres. I've not needed one yet (I run Schwalbes...) but if I did, I am confident that these little and light beauties would serve the job nicely. I am loving the fact that they are tiny! They are so small I can chuck 2 in my saddlebag. They seem nicely made and did I mention they are light?! Wish they were a bit cheaper but worth it, even if I never use them just because of the size and weight - I will be carrying them on every ride after all.
