Preparing for the Course

Have your bike checked over before the ride. Make sure everything is tight and properly adjusted, or take it to a trained Erik’s mechanic. They’ll gladly look it over and make sure everything is safe.

Remember to plan for the unexpected. Erik’s recommends on every ride that you keep the following in your hydration pack or seat bag:

  1. Spare tube
  2. Patch kit
  3. CO2 inflator with multiple cartridges or pump.
  4. Multi-tool
  5. Tire levers

For a long ride or race, you should add the following if you don’t already carry it:

  1. Tire boot for patching large cuts in tires
  2. Chain “quick” link to make field repairs
  3. Chain tool
  4. Back up energy food as a reserve tank

Erik’s mechanics will be on hand to make final adjustments or help out at the aid stations where possible. For more ideas, check out these recommendations or stop by one of Erik’s locations near you.
