Key Features to Look For
When you shop for a 150mm rear shock, check for these important features.
Adjustability
- Rebound Damping: This controls how fast the shock springs back after being compressed. Look for adjustable rebound. It helps you fine-tune the ride for different terrains.
- Compression Damping: This controls how the shock handles bumps. Some shocks let you adjust this. It can help you pedal more efficiently or soak up bigger hits.

Other Important Features
- Eye-to-Eye Length: This is the distance between the mounting holes. Make sure it matches your bike’s frame.
