Review on 🚴 DUROLITE Road Bike Tubes with Threaded Presta Valve, 3-Pack – Fits 700c Road Bicycle Tires, Removable Valve Core, 700 x 18-26c by Samuel Groove

I have been a road, triathlon and mountain bike enthusiast for over 12 years. These whistles are by far the worst whistles I have ever bought. The first drawdown after 4-5 hours of road riding was weird, but it happens. The next tube took a little longer, probably 400 miles, before the valve stem head broke and I couldn't inflate the tire anymore. Okay, let's move on to the next one. Shallow pin hole when I partially inflated it to match the rim. I bought them for light work, nothing heavy, just for cycling/city trips. It's scary to imagine how they will stand up to tougher conditions.
