How to Change a Mountain Bike Inner Tube: A Step-by-Step Guide
To change a mountain bike inner tube, first, detach the wheel from the bike frame, then remove the tire and the old inner tube completely. Next, check the cause of the flat tire, make sure it’s not a sharp object still lodged inside the tire and recheck the tire to ensure that the tube doesn’t become punctured again. After that, take the new inner tube and place it inside the tire while making sure it is not pinched or twisted. Finally, mount the tire back onto the rim and inflate the tire to the recommended pressure.
