Review on 🚲 LotFancy 27.5 Mountain Bike Tubes (2 Pack) - Schrader Valve (32mm) - Tire Levers Included - Various Sizes (1.75 to 2.40) by Michael Nard

Mine came as a pair in a plastic box with no instructions or other materials. The best advice I can give is to inflate enough air to shape them before putting the tube on the impeller. This will help prevent something from pinching the inner tube and essentially destroying it as this will cause further flattening. Comes with a pair of tire mounting arms that are. I found myself a bit small and clumsy but my eyesight is pretty poor initially so your mileage may vary. Also remember that I am not a top cyclist. My bike is a Walmart bike which helps me with personal fitness. I'm telling you this so you know, although I'll say it "works", you have to understand that I'm not very good with bike materials. I don't do descents, jumps and the like. However, for my needs, which is a basic camera to keep me going, they seem to work well. I'm only giving it three stars because I think this is aimed at the entry-level market and I don't want people's expectations to get too high. Good to have as emergency gear but if you are looking for performance. go somewhere else
