Inner tube Presta 700x38/45c, 48mm
You can read the size on the side of the tyre: the first number is the wheel diameter, the second is the width.
MTB inner tubes are made for a range of widths, so they don't have to fit exactly — just stay within the specified range. Choose the valve according to the hole in the rim; the thicker type is more common off-road. Reinforced inner tubes add a few tens of grams and significantly reduce the number of punctures from thorns and rocks, making them worth it on the trail. Always take a spare one in your backpack, even if you ride tubeless.
