80mm Travel Rear Shock Length: Everything You Need to Know

When it comes to mountain biking, the rear shock is one of the most crucial components to ensure a smooth ride. Among the various specifications, the 80mm travel rear shock length is a common choice, especially for cross-country riders or those looking to maintain a lightweight, efficient bike setup without sacrificing performance. In this article, we will dive deep into the 80mm travel rear shock length, its benefits, and how it impacts your ride. Additionally, we will answer frequently asked questions to help you make an informed decision when choosing the best rear shock for your needs.

What is 80mm Travel Rear Shock Length?

The term “80mm travel rear shock length” refers to the amount of suspension movement the rear shock provides. In simple terms, travel is the distance the shock compresses under force. A rear shock with 80mm of travel means the suspension can compress 80mm (or 3.15 inches) when encountering bumps, drops, or other obstacles on the trail.

The 80mm travel rear shock length is commonly used on cross-country (XC) bikes or other lightweight bikes where efficient pedaling and control are a priority. This shorter travel is ideal for riders who need to maintain a fast, responsive bike while still benefiting from a degree of cushioning when riding over rough terrain.

Why Choose 80mm Travel Rear Shock Length?

  • Efficiency and Speed: One of the biggest advantages of a 80mm travel rear shock is its ability to keep the bike responsive. With less travel, the bike remains efficient and quick, which is especially important for cross-country riders who focus on speed and endurance. Shorter travel also means less weight, allowing you to conserve energy and ride faster for longer periods.
  • Improved Climbing Ability: XC riders often face steep ascents, and the 80mm travel rear shock length helps maintain pedal efficiency during climbing. With less suspension travel, there is less “sag” when you push down on the pedals, meaning less energy is wasted.
  • Smoother Rides: While 80mm of travel is less than what you’d find on downhill bikes or enduro models, it still provides enough cushioning to make rough trails more comfortable. You can enjoy the benefits of shock absorption without sacrificing too much efficiency.
  • Lightweight Design: Bikes designed for cross-country riding often prioritize weight savings, and an 80mm travel rear shock length is typically lighter than shocks with longer travel. This makes it ideal for riders looking to shed grams without compromising too much on comfort.

Factors to Consider When Choosing an 80mm Travel Rear Shock Length

  • Riding Style: If you are a competitive cross-country racer or enjoy long rides on smooth trails, an 80mm travel rear shock length could be the best option. However, for riders who often tackle technical or aggressive trails, a rear shock with longer travel may be a better choice.
  • Bike Geometry: The overall geometry of your bike plays a role in how the shock interacts with the rest of the frame. Make sure the shock length matches the manufacturer’s specifications to ensure optimal performance and safety.
  • Shock Type: There are two main types of rear shocks: coil and air. Air shocks are typically lighter and more adjustable, making them a popular choice for XC bikes with 80mm travel rear shock lengths.
  • Adjustability: Some 80mm travel rear shock lengths offer adjustable rebound and compression settings, giving you more control over how the shock performs. This is particularly useful for riders who like to fine-tune their suspension to different trail conditions.

How Does 80mm Travel Compare to Other Travel Lengths?

  • Shorter Travel (50mm-70mm): Great for cross-country or road bikes where efficiency and speed are paramount. Shorter travel can provide a more responsive feel, but it may not handle rough trails as effectively as longer shocks.
  • Medium Travel (100mm-140mm): Perfect for riders who want a balance between climbing efficiency and trail comfort. This range is ideal for trail bikes that need to handle a variety of terrain.
  • Longer Travel (150mm+): Designed for aggressive riding, enduro, or downhill bikes. These shocks provide maximum comfort and control on technical and rough terrain but tend to be heavier and less efficient for long-distance riding.

Conclusion

The 80mm travel rear shock length offers a solid balance between efficiency and comfort, making it a popular choice for cross-country riders. Its lightweight design, minimal sag, and ability to absorb impacts without compromising speed make it an excellent choice for those who want to ride fast on smooth, technical trails. When choosing your rear shock, consider your riding style, the terrain you typically encounter, and your desired bike geometry to make the best decision.


Frequently Asked Questions (FAQ)

Q1: What type of bike is best for using an 80mm travel rear shock length?

An 80mm travel rear shock length is best suited for cross-country bikes, lightweight trail bikes, or endurance racing bikes. It provides an excellent balance between comfort and performance without adding unnecessary weight.

Q2: How does an 80mm travel rear shock length affect pedaling efficiency?

An 80mm travel rear shock length helps maintain pedal efficiency by minimizing suspension sag. This makes it easier to climb and maintain speed, which is especially beneficial on cross-country trails where efficiency is key.

Q3: Can I use an 80mm travel rear shock on a bike designed for longer travel?

While you can technically use an 80mm travel rear shock length on a bike designed for longer travel, it may affect the bike’s geometry and overall performance. Always check with the manufacturer or a bike mechanic to ensure compatibility before making any changes.

Q4: Is 80mm travel rear shock length good for technical trails?

An 80mm travel rear shock length is suitable for smooth to moderately technical trails, but if you often ride on extremely rough or rocky terrain, you may want to consider a longer travel rear shock for better impact absorption and control.

Q5: What is the difference between coil and air shocks for 80mm travel rear shock length?

Coil shocks are generally more durable and provide a more consistent feel, but they tend to be heavier. Air shocks are lighter, adjustable, and offer more fine-tuning options, making them a common choice for cross-country bikes with 80mm travel rear shock length.


By understanding the significance of the 80mm travel rear shock length, riders can make better decisions when customizing their bikes for comfort, speed, and performance. Whether you’re an experienced cross-country rider or a beginner, this shock length offers a great balance for tackling a variety of trails.
