In order to enjoy your Haleakalā ride to the fullest, you must use the appropriate gear, including a properly sized mountain bike. Let’s find out more about proper bike sizing and why it’s so important on any mountain ride.

Why Bike Fit Matters

Mountain biking is a dynamic sport that involves many challenges that are unique to the landscape being traversed. Sharp turns, steep grades, and lengthy descents are all part of the adventure. Having a properly sized bike will ensure that you can maintain control during your ride, increase your comfort, and keep you on trail and on schedule. An ill-fitting bike will cause distraction, fatigue, discomfort, or in a worst-case scenario, injury or worse.

Step 1: Understand the Basics of Bike Sizing

There are several factors that must be considered when sizing a bike, including frame height, standover height, reach, and wheel size. Each factor must be carefully measured and matched to the rider to ensure the most comfortable and efficient ride possible.

Step 2: Know Your Measurements

Before being sized for a mountain bike, gather these key measurements:

  1. Height: Stand straight and measure from the floor to the top of your head
  2. Inseam: Measure from the floor to your crotch while standing barefoot
  3. Arm Length: Measure from the tip of your shoulder to your wrist
  4. Torso Length: Measure from the base of your neck to the top of your hips.

Use these measurements to consult a bike size chart specific to the brand or model of mountain bike you’re considering. If you’re using a bike tour company that provides a bike, provide these measurements to the company to get the bike most appropriate for you.

Step 3: Test the Fit

No matter if you’re buying a mountain bike, renting one, or your bike tour company is providing one for free, always take a test ride before heading out on your mountain ride. Here’s what to check during your test ride:

  • Comfort: When sitting on the bike with your feet in the pedals, your legs should be fully extended when the pedal is at its lowest possible point, but not overextended
  • Control: Be sure that the bike feels balanced while you are riding and that you feel in full control of all movements
  • Handlebar Reach: You should never have to stretch to reach the handlebars when sitting on the bike, nor should your arms feel cramped

Step 4: Customize Your Bike Setup

Even a bike that is perfect for your measurements may need some minor adjustments for maximum comfort. Your bike tour company will help you make these customizations, including adjusting the seat height so that your legs aren’t under or overextended, adjusting the handlebar height so you can maintain a neutral grip position, and the pedals to fit the footwear you are using.

Step 5: Consider the Terrain

Riding on mountain terrain, like Mount Haleakalā, requires a durable and versatile mountain bike. Things to consider before taking off include:

  • Is the suspension full or front only? Full suspension is best for control on rough terrain, but front suspension is best for climbing.
  • Are the tires wide enough to grip the terrain, and how good is the tire tread?
  • For steep grades, a bike with a wide gear range is always best.
