3. Cane Creek DBair IL: Best Tunability
The Cane Creek DBair IL is a tuner’s dream, offering independent high and low speed compression and rebound adjustments. In our evaluation, this level of control allows riders to dial in the shock for specific trails and preferences. The Climb Switch is effective at reducing bob, making it a strong choice for riders who tackle steep climbs. Owner feedback often mentions that once set up correctly, the shock performs exceptionally well across varied terrain.
However, the DBair IL has a steep learning curve. Many owners report needing multiple rides and adjustments to find the sweet spot. It is also heavier than air shocks from Fox or RockShox, which may matter on weight-conscious builds. If you enjoy tinkering and want maximum control, this shock is fantastic. But if you prefer simplicity or have a limited budget, you might find it frustrating.
- Four-way independent adjustment for compression and rebound.
- Climb Switch provides a firm platform for climbing.
- Self-contained design with external reservoir.
Pros: Unparalleled adjustability for fine-tuning; Excellent climbing performance with Climb Switch
Cons: Complex setup can be intimidating; Heavier than some competitors
4. Marzocchi Bomber Air: Budget Pick
The Marzocchi Bomber Air is a no-frills shock that delivers solid performance at a budget-friendly price. We researched owner feedback and found that it offers a surprisingly plush feel for its price, thanks to its well-tuned air spring. The lockout is effective for climbing, and the rebound adjustment allows basic tuning. Durability is also a strong point, with many riders reporting trouble-free use over multiple seasons.
On the flip side, the Bomber Air lacks the high-speed compression adjustment found on more expensive shocks, which can limit its performance on fast, rough descents. Some riders also note that the lockout lever feels a bit stiff. If you are a recreational rider or on a tight budget, this shock is a smart choice. However, aggressive all mountain riders who push hard may find its damping insufficient.
- Simple, reliable design with fewer seals for reduced maintenance.
- Plush air spring with good small bump compliance.
- Affordable price point without major sacrifices in performance.
Pros: Great value for money; Easy to set up and maintain
Cons: Limited adjustability (no high-speed compression); Not as refined as premium shocks on rough terrain
5. Ohlins TTX22M: Premium Coil
The Ohlins TTX22M is a coil shock that sets the standard for traction and small bump compliance. In our evaluation, its Twin-Tube technology delivers consistent damping even during extended descents, reducing fade. Owner feedback often highlights the shock’s ability to keep the tire glued to the ground, inspiring confidence in corners. The build quality is exceptional, with precise machining and smooth adjustments.
However, the TTX22M is heavier than air shocks, and the coil spring must be changed to match rider weight, adding cost and complexity. It also has limited external adjustments compared to some air shocks, which may not suit riders who want fine-tuning. If you prioritize grip and are willing to deal with the extra weight and spring setup, this shock is outstanding. But for weight-conscious riders or those who prefer air springs, it may not be ideal.
- Twin-Tube design provides consistent damping and heat management.
- Smooth coil spring feel with excellent traction.
- High-quality construction and materials.
Pros: Incredible small bump sensitivity and grip; Consistent performance on long descents
Cons: Heavier than air shocks; Coil spring requires swapping for different rider weights

The DT Swiss R 535 One stands out with its compact piggyback design that minimizes weight and improves heat dissipation. Our research shows that the damping is consistent and predictable, making it a good choice for riders who value reliability. The platform switch is effective for climbing, and the air spring offers a linear feel that many riders appreciate. Owner feedback is generally positive, especially regarding its performance on smoother trails.
However, the R 535 One offers only basic adjustment (rebound and low-speed compression), which may disappoint tuners. Additionally, DT Swiss parts can be harder to find in some regions, and service intervals are less standardized. If you want a distinctive, well-engineered shock and don’t need extensive adjustability, this is a solid option. But for those who want to fine-tune every aspect, it may feel limiting.
- Unique piggyback reservoir design for consistent damping.
- Linear air spring with good support.
- Easy-to-use platform switch for climbing.

Frequently Asked Questions
What is the difference between air and coil rear shocks for all mountain riding?
Air shocks are lighter and offer adjustable spring rate via air pressure, making them versatile for different rider weights and terrain. Coil shocks provide a more linear spring rate and superior small bump sensitivity, but they are heavier and require swapping coils to change spring rate. For all mountain riding, air shocks are more common due to their adjustability, while coil shocks are favored by riders who prioritize traction and plushness over weight.
How do I choose the correct shock size and stroke for my bike?
You need to match the shock’s eye-to-eye length and stroke to your frame’s specifications. These measurements are usually listed in your bike’s manual or on the manufacturer’s website. Installing a shock with incorrect dimensions can damage the frame or affect geometry. Always verify compatibility before purchasing.
What does low-speed compression adjustment do?
Low-speed compression (LSC) controls how the shock responds to slower inputs like pedaling, braking, and gradual bumps. Increasing LSC reduces bob and improves climbing efficiency, while decreasing it allows more movement for better traction. It is a key tuning tool for balancing support and comfort.
How often should I service my rear shock?
Most manufacturers recommend a basic air can service every 50 hours of riding, and a full damper service annually or every 100-200 hours, depending on conditions. Regular maintenance ensures consistent performance and extends the shock’s life. Check your owner’s manual for specific intervals.
Can I use a coil shock on a bike designed for air?
Yes, as long as the shock dimensions (eye-to-eye and stroke) match, and the frame has clearance for the coil spring. Coil shocks are often slightly heavier and may affect the bike’s suspension kinematics. Some frames are optimized for air shocks, so check with the manufacturer for compatibility.
