TAC-9 Tube, 26" x 1.90-2.35" PRESTA Valve, SELECT 32mm or 48mm Valve Stem Length (ISO 559)

This was my first time ever replacing a tube on a bike. Just never had a need to do it before now. So with only a couple of YouTube videos under my belt, and my newly purchased tire levers, I went to work with these tubes and a new set of tires. Took me maybe 10 minutes for both wheels. I can easily see this being a 5 minute job for anyone who has done it once or twice. At any rate, tubes worked out great, both are holding air, presta valves are a tad longer than I'd like, but that's on me because I ordered that length. Unless they blow out on me within a couple of weeks, I'd say it's a pretty darn good deal.

Love the tubes and Presta valves, however after mile 30 the rear suddenly lost pressure ordered a replacement hopefully it’s nothingEdit checked the tube today, it opened up on a ridge. Looks like a failure I’ll patch it and keep it as a spare.

Wow! I received these fast and I don't even have prime. The seller of this product is exceptional. Thank you Andy.

Excellent deal and very fast shipping. Will buy again.

Gets me down the road.

So far, so good.I have them in a 1.8 tire and 2.3. Good fit.

Aired up perfectly.

During regular use these both tubes failed within a couple of weeks. This should not be so. It has led me to believe that this is a defective batch/poor quality. I will not purchase this brand again.
