To build a bicycle wheel, you need four essential components:

• Rim – The outer hoop that holds the tire
• Hub – The center of the wheel that attaches to the bike
• Spokes – Connect the hub to the rim and provide structural strength
• Nipples – Small threaded pieces that secure spokes to the rim

In addition, many builders use:

• Spoke washers – Improve fit and reduce stress at the rim
• Spoke prep or thread compound – Helps prevent loosening and corrosion

Choosing high-quality components—especially spokes and nipples—is critical for building a strong, durable, and long-lasting wheel.
