When it comes to mountain biking, the rear shock is a critical component, significantly influencing your ride’s comfort, control, and overall performance. For riders seeking to optimize their setup, understanding concepts like spring travel and the available options is essential. If you’re considering components for a 185×55 shock, FOX Racing Shox offers an innovative solution with their Super Light Steel (SLS) springs.
What is Spring Travel and Why Does It Matter for Your Shock?
Spring travel, in the context of rear shocks, refers to the maximum distance the shock can compress. This travel is crucial because it dictates how much impact your bike can absorb, directly affecting how smoothly you ride over rough terrain. A 185×55 shock, for instance, indicates a shock with a 185mm eye-to-eye length and a 55mm stroke. The stroke, in this case, is closely related to the potential spring travel. Matching the correct spring travel to your shock and bike frame is vital for optimal suspension performance. Too little travel, and you might experience harsh bottom-outs; too much, and you risk frame damage or inefficient pedaling.
Introducing FOX SLS Springs: A Lightweight Upgrade
FOX Racing Shox has engineered their Super Light Steel (SLS) springs as a high-performance alternative to traditional steel and even titanium springs. Designed for DHX and VAN rear shocks, these SLS springs offer a significant weight reduction compared to standard steel, while also presenting a more budget-friendly option than titanium. This makes them an appealing upgrade for riders looking to enhance their bike’s responsiveness and handling without breaking the bank.
The Technology Behind SLS Springs
FOX achieves this weight reduction through a combination of advanced materials and manufacturing processes. SLS springs undergo a proprietary surface treatment and stress relief process. This sophisticated treatment eliminates residual stresses within the spring material, enabling it to withstand higher stresses. Consequently, FOX engineers can utilize a smaller wire diameter and fewer coils in the spring design. This optimization is key to creating a lighter spring without compromising its strength or durability. Each SLS spring is easily identifiable by its vibrant orange color and clear markings indicating the spring rate (in lbs/in, with 25 lb increments) and the maximum compatible shock travel.
Compatibility and Range of FOX SLS Springs
FOX SLS springs are available in a range of spring rates and travel options to suit various rider weights, riding styles, and shock configurations. They are designed to be paired with FOX DHX and VAN rear shocks. It’s crucial to select a spring with the correct rate for your weight and riding preferences and ensure the spring’s maximum travel is appropriate for your shock. For instance, for shocks with 2.25″ of travel or less, FOX offers SLS springs like the Spring: (T) [1.385 ID X 550 lb/in, 2.25 Travel] SLS. This specific spring is designed for shocks with a maximum of 2.25 inches of travel and has a spring rate of 550 lbs/in.
For comparison, FOX also provides standard steel springs, which are black and marked with their spring rate and total spring travel. These standard springs should be paired with shocks having less travel than indicated on the spring itself.
Choosing the Right Spring for Your 185×55 Shock
Selecting the correct spring is vital for optimal suspension performance. When considering an SLS spring for your 185×55 shock, you need to know your current spring rate and desired performance characteristics. The tables provided by FOX (as shown in the original document) are invaluable resources for identifying the precise SLS spring model that matches your required spring rate and shock travel. Always refer to the manufacturer’s specifications and guidelines to ensure compatibility and safe operation.
Conclusion: Upgrade Your Ride with FOX SLS Springs
FOX SLS springs represent a significant advancement in rear shock spring technology. They offer a compelling combination of lightweight performance, durability, and affordability, making them an excellent upgrade option for riders seeking to enhance their mountain biking experience with 185×55 shocks and other compatible models. By understanding spring travel and exploring the FOX SLS range, you can fine-tune your suspension for improved trail performance and riding enjoyment.
