Ultraverse Bike Inner Tube for 700x23-25c, 28 inch Bicycle Wheel Sizes with 48mm Presta Valve - Butyl Rubber Tubes for Road and Gravel Bikes - 2 Tubes with 2 tire levers Included

Excellent quality tubes that are thicker/more durable than competitors (Continental, Michelin, etc). They hold air very well, and although they weight a few grams more than those of other brands, I have great confidence in their quality and longevity.

It is unbelievable how poor quality tubes are now! I have had so many once reputable brands just go to pot. I have had seems split, valve stems just fall out, not being able to be patched on the road, etc.But these have worked out well. I have not had any stems fall out, the patch kit works on them, and compared to the Continental (which is also still of high quality) they are slightly thicker when installed and inflated. This is fine with me because I don't want to get a flat on the road and I am willing to to trade weight for that. The other thing a thicker installed tube does for you is they hold the air presurre longer, so I don't have to pump up before every ride. The 25c Continental's are really 23c in my book as they are quite thin when expanded inside a 25c tire and more prone to being punctured. I would and have bought these Ultraverse tubes again!

Great product strong built well worth the price can't beat it they work amazing.

Bought these tubes for a used bike I recently purchased. The rim punctured the tube. Ultra verse customer service promptly sent me a replacement. The tubes are great quality.

Buen material, práctico!
