Schwalbe 3-16' fietsbinnenband, verpakking kan afwijken, kleur zwart, maat 40 cm

This inner tube ruptured within one day of being installed, and the bike was never even ridden! It was inflated to 50 psi, and left overnight -- flat tire when I went to ride the next morning. I disassembled the wheel, and found no sharp edges on the interior of the rim or spokes (rubber rim strip also installed). The tube just simple ruptured on the interior face. Very poor quality -- possibly even a knock-off, as I've had good luck with other Schwalbe-branded items in the past (tires).

子ども用自転車（タイヤは16×2.5）のメーカー不明初期チューブがあっという間に接合部で裂けたので、ちゃんとしたシュワルベに交換。当分はたぶん大丈夫でしょう。バルブ部が全ネジ＋ナットなのでポンプを挿すときも作業しやすいです。

A me serviva per la bici pieghevole STRIDA con pneumatico SCHWALBE BIG APPLE 16 x 2.00 (50-305) e la camera d'aria consegnata è esattamente quella che occorre per questo tipo di pneumatici. Pienamente soddisfatto del prodotto consegnato.

Given the time it takes to replace a defective inner tube it make sense to buy quality which is exactly what these Schwalbe's are. The giveaway is the manner in which the valve stem is welded to the inner tube. In addition, the stem is made of metal and has a ring nut to prevent the stem from being pushed into the inner tube when the tube is being inflated.

Entrega rápida y el material es de buena calidad. La válvula trae tuerca de seguridad. Todo ok
