TAC 9 Bike Tube, 700 x 35-40 (27 x 1-3/8) Regular Schrader Valve, 32mm (ISO 622/630)

It’s hard for me to criticize them as they still hold air months later. I previously bought a different brand and they didn’t even inflate past 20psi before blowing, so kudos. IJust don’t trust any tubes on Amazon as all brands are “supposedly” all made in the same factory of the same country, but somethings amiss. Not sure if they are factory rejects or some other new companies cheap knock-off.When it comes to something you depend on, like bike tubes, I’ll be buying my tubes from a reputable retailer like REI. I’ve had 100% success with their in-house brand.

Excellent AAAAAAA ++++++++++++

I used these for 2 Trek bikes that need new tubes/tires. they worked perfectly and were value priced. I would recommend!

Working great for me; would buy again.

Received 2 tubes and 2 rim strips, as advertised. Tubes labeled as Kenda - Taiwan. Only used 1 tube and strip. Keeping the other as a spare. Tube's been on the bike for a week without any issues.
