Before you start, this is your official warning that cleaning your chain is a dirty job. So take off that tux, pull on some gloves, and let’s get started!
1. Determine what your tire pressure should be. Every Bontrager tire has a recommended pressure range right on the sidewall of the tire.
2. Check to see if your pump is compatible with the type of valve on your tires. All tires have either Schrader or Presta valves, and most Bontrager pumps are compatible with both! If your pump isn’t, you can purchase an adapter at your local bike shop.
3. If your valves have dust caps, remove them.
4. If you’re using a Schrader valve, you’re ready to get pumping!
5. If you’re using a Presta valve, unscrew the end to open it. You can check that it’s loose enough by pressing the valve core inward. If you feel a burst of air, you’re good to go.
6. Secure your pump to the valve by pushing the pump head down on the valve as far as it can go. Then, lock the head by lifting the lever.
7. Wiggle the head. If you feel the valve moving inside, it’s not secure enough and needs to be pushed down even more.
8. Once the pump is securely attached, begin pumping. If you hear air hissing out as you pump, the head still isn’t secure enough. Repeat step 7, and try again!
9. Keep an eye on the pressure gage as you pump. Stop pumping when you’re within the range printed on the side of your tire.
10. Release the pump head by pressing the lever down and quickly pulling the head off the valve. If you’re using a Presta valve, don’t forget to close it.
