This guide covers how to replace an inner tube with Presta valve on a Fuji road bike.
Bikes are one of the most common forms of transportation, and they require frequent maintenance if they are to remain at their peak condition. The inner tube cushions the bike tire from impacts, and it helps the bike absorb shock from a rough and bumpy terrain. Punctures, manufacturing defects, or changing tire size are among the many reasons one should know how to replace the inner tube of a bike. Luckily, this a process that is quick and not too complex, so any person with a tire lever and an air pump can do it.
Once you have completed the steps, be sure the inner tube is inflated to the correct pressure. Now you should be able to enjoy a smooth ride once again!
