Review on 🚴 TAC 9 Bike Tubes, 700x35-40 (27x1-3/8) Schrader Valve, 32mm (ISO 622/630) by Jason Gopinath

The 700x35-40 Tac 9 inner chamber seems to fit. This particular pipe had a Schrader valve with a cap. This is the type of valve seen on cars. To install such an inner tube, first remove the old inner tube and inspect the inside of the tire to make sure there are no sharp objects stuck in the tread or sidewall. Then draw some air into the tube and dust the tube and tire with a powder such as talcum powder. Hook one bead of the tire onto the rim, insert the tube and valve, and then attach the other bead to the tire. Using a manual air pump, slowly inflate the tire, periodically checking to make sure the bead is flat and the valve stem is straight. Check and adjust according to tire side pressure. My experience with this tire shows that it has failed. The tire was flat the morning after driving. After checking the tube, it burst and there was no corresponding sharp object in or through the tire. I think the tube is defective. I have found that this is typical for economical lamps. Purchase this handset at your own discretion.
