Review on 🚲 TAC 9 Tube for Bicycles - 700c x 18-23, Presta Valve, 32, 48, 60 or 80mm Length - Choose Valve Size and Money-Saving Option in 1 Pack or 2 Pack by Bomba Ton

judging by the reviews these whistles are scattered around the world, I don't know why? The product description states that these tubes can withstand high tire pressures and for me they have held up very well. I run Vredestein race tires on a Cannondale road bike at very high pressure, over 160psi. These tubes seem to handle it with no problems. I ride busbars so maybe this will help? I'm not sure, but these bulbs appear to be of much better quality than the Giant bulbs they replaced, giving me pinches both front and rear. It appears that the TAC 9 tubes are only slightly thicker than the Giant tubes and therefore have no pinch points.
