Review on 🚴 Improved SEO: Sunlite Thorn Resistant Bike Tube - Size 27 x 1-1/4 (700 x 30-35) with SCHRADER Valve by Fritz Wiest

Sunlite Thorn Resistant Inner Tubes 700c x 30-35 They are actually made by Kenda. There are two markings on the tubes: Kenda 700c x28-32 and then Sunlite 700c x 30-35. Having removed my original tube (Kent Bicycle from Wal-Mart) which was marked 700c x 35, I would say these Sunlite tubes definitely fit the Kenda 700c 28-32 size. Sunlites are made from very thick rubber. They remain round even when completely deflated. No wonder they are puncture resistant as each Sunlite tube weighs 420 grams while my bike's original tubes weighed only 180 grams. The Schrader valve is a standard height, making it unsuitable for some aero wheels used on Kent bikes. from department stores. These bikes require a Schrader valve stem that is about the same height as the Presta. Overall: 4/5 stars, Kenda brand Sunlite tubes in 2 different sizes (seems to be much closer to 700c x30-32 than 30-35), weighs more than twice as much as a standard camera.
