Bicycle Rear Shocks

Description

Bicycle rear shocks are an essential component of full-suspension bikes, designed to absorb impact and improve ride comfort and control on rough terrain. They connect the rear triangle of the bike frame to the main frame, enabling suspension movement. Here’s an overview:

Key Components

1. Shock Body: The main cylinder containing air, oil, or a spring.
2. Spring: Can be a coil spring (metal) or air spring.
   • Coil springs: Durable and consistent, ideal for downhill biking.
   • Air springs: Lightweight and adjustable, suitable for cross-country and trail riding.
3. Damper: Controls the speed of suspension compression and rebound using oil or other mediums.
4. Mounting Hardware: Includes bolts, bushings, and spacers for attachment.

Types of Bicycle Rear Shocks

1. Air Shocks:
   • Lightweight and adjustable.
   • Commonly used in trail and cross-country bikes.
   • Offers fine-tuning for rider weight and riding style.
2. Coil Shocks:
   • Heavier but provides consistent performance under high stress.
   • Popular for downhill and enduro biking.
3. Hybrid Shocks:
   • Combine features of air and coil shocks for versatility.

Key Adjustments

1. Rebound: Controls the speed at which the shock extends after compression.
2. Compression: Adjusts how the shock absorbs impacts.
   • Low-Speed Compression (LSC): For small bumps and pedaling efficiency.
   • High-Speed Compression (HSC): For large impacts like jumps or drops.
3. Sag: The amount the shock compresses under the rider’s weight. Typically set to 25-30% of total travel.

Popular Brands

1. Fox Racing Shox: Known for high-performance air and coil shocks.
2. RockShox: Offers a range of models for different disciplines, including the Monarch and Super Deluxe.
3. DVO Suspension: Premium options with advanced adjustability.
4. Marzocchi: Durable and robust shocks for downhill and freeride biking.
5. Ohlins: High-end shocks with exceptional control and damping.

Maintenance Tips

1. Clean the shock regularly to prevent dirt buildup.
2. Check air pressure (for air shocks) or spring preload (for coil shocks).
3. Service seals and lubricate pivots periodically.
4. Follow manufacturer guidelines for rebuild intervals.
