DMLNN 28 700x18-25C Road Bike Replacement Inner Tubes Schrader Valve 48mm for Road Bikes with Tire Size of 700c x 18, 23, and 25 (4 Inner Tubes with 2 Tire Levers)

La verdad me sorprendió la calidad de los tubos por el precio. He tenido tubos continental, bontrager, chinos, Schwalbe etc, pero results han sido los mejores. Sufrí de varias pinchaduras en dos semanas, era frustrante. Compré estos tubos y no he tenido ninguna en un mes, no sé si sea coincidencia pero el hecho es que se notan de mejor calidad desde que las sacas de su caja

ممتاز

Great price and product. Prompt service. Will purchase from this company again.

Purchased to replace a set that popped two parallel splits every time I hit a bump. Obviously a manufacturing issue. Bought these because the marketing pitch claimed it had an extra .1 millimeter of material over normal tires. First red flag was that they looked remarkably similar to the last set, tho I paid more for these. (I used "get what you pay for logic".) But I wishfully willed myself to believe they felt thicker anyhow. Yet today, two weeks after installing one, it popped the same two splits as the last batch did when I hit a bump. See pic.And, of course, these now list as "Currently Unavailable" less than three months after purchase, which seems to happen with every Amazon product I have trouble with. But if they do come available, I strongly suggest you avoid.

Product as advertised. Delivery was next day. What more can you ask?
