How to Choose a Rear Mountain Bike Shock | Boyer Cycling

Choosing the Perfect Rear Shock for Your Mountain Bike
Your rear shock is crucial for controlling traction, absorbing bumps, and ensuring a smooth ride through technical terrain. Whether you're tackling rock gardens or sending it off drops, selecting the right shock can make or break your riding experience. Here's how to make the best choice.
Understanding the Key Numbers
Rear mountain bike shocks come with various specifications that can feel overwhelming at first. Here’s what they mean:
1. Shock Size (Eye-to-Eye & Stroke Length):
•    Eye-to-Eye Length – The total length between the mounting bolts, usually measured in millimeters (e.g., 210mm, 230mm).
•    Stroke Length – The distance the shock compresses under load, affecting suspension travel (e.g., 60mm, 65mm).
You must match both measurements to your bike frame to ensure compatibility. Check your bike manufacturer’s specifications to confirm the correct sizing.
2. Spring Type (Air vs. Coil):
•    Air Shock – Lightweight and adjustable; ideal for trail and all-mountain riding.
•    Coil Shock – Offers plush feel and better small bump sensitivity; great for downhill and enduro.
Choosing between air and coil depends on your weight, riding style, and terrain preference.
3. Shock Tune & Adjustability:
Look for shocks with:
•    Compression & Rebound Adjustments – Allows you to fine-tune how quickly the shock reacts.
•    Lockout or Pedal Platform – Helps with climbing efficiency by reducing unnecessary movement.
If you're into aggressive downhill riding, a shock with more tuning options can provide better control.
How to Ensure Proper Fit
•    Check Your Frame Compatibility: Not all shocks fit every frame, so verify dimensions before purchasing.
•    Consider Your Riding Style: If you're into technical descents, a coil shock may be best; for efficiency in pedaling, an air shock is the way to go.
•    Consult Manufacturer Guidelines: Brands provide recommended shock specs for each bike model—always check before upgrading.

Selecting the right shock isn’t just about numbers; it’s about how it complements your riding style and terrain. A well-chosen rear shock can enhance control, comfort, and overall bike performance—so choose wisely and ride with confidence!
