1. Mountain biking myths often aren't true.
2. Injuries often happen at the end of the day during the last few runs.
3. Tire pressure increases by about 10 to 15 psi at high altitudes due to decreased temperature.
4. Tires recommended to be inflated between 17 and 35 psi won't explode at high altitudes.
5. Bunny hopping on a mountain bike is mostly in your arms and shifting your body weight, not in your feet.
6. Fast engagement hubs can negatively affect suspension and cause pedal kickback.
7. Quick release skewers had a recall in 2015 but are safe if installed properly.
8. Storing bikes vertically won't ruin suspension if done for a reasonable amount of time.
9. Master links (quick links) on bike chains are single-use according to manufacturers, but many people reuse them without issues.
