SCHWALBESV19 Inner Tubes - 27.5 (650b) / 29er x 1.5-2.35", Presta Valve (2 Pack)

My factory tires had a puncture, but I was planning to swap them out for different models. So I went ahead and changed the inner tubes as well. I went with the Schwalbe SV19 Inner Tubes - 27.5 (650b) mostly because of the price and immediate delivery date. One of the two only lasted a couple of weeks.After a puncture two nights ago, I ordered the Continental MTB Bike Tubes 27.5" instead. The size was easier to get under the tire, they installed easier, and the tire bead seated much easier. Maybe others have had different experiences, but I am going to stick with the Conti from now on.
