Review on 🚴 Schwalbe Tube Nr.17: 28/27 Inch Bicycle Inner Tube for Enhanced Performance by George Bell

Great handset and well worth the extra money. I threw away my existing lamps (which have been repurposed to onboard spares) that I bought here a few years ago due to their inherent porosity. I had to inflate my tires every day (up to 90psi). They lost about 20psi a day and I found no leaks when they were taken off. These Schwalbe tubes will hold pressure at an acceptable level for about 5-7 days, and even then they're pretty tough. Also note that the boxes marked in green contain Schrader valves, although they are all metal and come with a lock nut. I almost sent them back thinking it was the wrong valve until I took a closer look. I will only use this brand in the future. Unlike many bike inner tubes, this is a high quality product with very little leakage.
