Vorsprung Secus Air Spring Kit (Forks only)

$450 for part alone, or $650 including a full Hyperformance Service and installation

The Vorsprung Secus air spring is the first air-sprung fork system that will give you a feeling truly comparable to that of a coil fork. Coil-sprung suspension has provided the benchmark for performance over recent years, but with the Secus you're able to match that performance without the added weight of a coil spring, and even maintain some of the positive characteristics expected from air suspension. The first 2/3rds of your travel will be supple, compliant, and linear, just like a coil fork, however, in that final third of the travel (where you need that added bit of security) you'll benefit from some natural progression that we expect from an air spring system. The end result is a system that will handle just about anything you can throw at it in the most controlled manner possible.

          

 












Benefits of the Secus

  • An enlarged negative air spring chamber delivers a soft, supple initial stroke for ultimate small bump compliance (yes, even compared to the Luftkappe)
  • Proprietary Midstroke Support Valve improves predictability and support beyond the sag point
  • Reduced lower leg pneumatic ramp means better scalability of the air spring, particularly for light riders who previously struggled to use full travel
  • Plush and predictable like a coil, bottomless like an air spring
  • Allows full use of travel in both directions - fully extends to topout without any quibbles (including on Debonair B1 air springs) and fully compresses without excessive ramp
  • Allows more lower leg bath oil to be used for superior lubrication
  • Considerably lighter than coil conversions - adds approximately 130g
  • Simple setup - inflate fork, bounce on it a few times, press MSV charge button, go ride
  • Compatible with OEM volume spacers for end-stroke progression adjustment
  • Compatible with other aftermarket top-cap systems such as DSD Runt and MRP Ramp Control
  • Lower compression ratios mean a more consistent spring rate
  • Transferrable between any Secus-compatible forks with only a footstud to change at most

    Vorsprung Smashpot Coil Conversion System (Forks only)

    $469 for part alone, or $669 including a full Hyperformance Service and installation

    If you don't mind the very small amount of added weight that comes with a coil spring the Vorsprung Smashpot coil conversion might be what you're looking for. Even with the newly released Vorsprung Secus air spring (see above) there are still benefits to a coil-sprung fork if you're chasing the absolute best performance. Some of these benefits include:

    •  Zero stiction or friction in a coil spring, and no moving seals in the spring system to wear out, cause friction or leak
    • Zero spring rate variation allowing more mid-stroke support and consistency
    • More oil in the fork - lubrication and service life are improved
    • Catering to rider weights from 45kg (100lbs) to 125kg (275lbs) with 11 coil spring rates
    • Allows lighter riders to get the most use out of their forks, and heavier riders the support they need without excessive air pressures

    • Only coil conversion system on the market allowing 180mm travel

       
    • Easily adjust your travel with internal spacers (please note the minimum & maximum travel of your fork as determined by manufacturer)Unique Hydraulic Bottom-out System reduces harshness
    • Can be transferred between different forks with minimal parts /cost (a purchase of a new top cap or foot stud)
    • Reliable and low maintenance, set and forget. User installable and serviceable
    • Weight increase of approximately 250-450g (dependent on spring rate and fork's existing spring system)

    Vorsprung Tractive Valve Tuning System (RS Monarch Plus and RS Super Deluxe Air/Coil shocks only)

    Installed in NSD workshop only - $380 including a full Hyperformance Service and installation

    With over seven years in development the Vorsprung Tractive tuning system has a wealth of time, research and testing behind it.  Teaming up with engineers from one of the worlds most advanced mathematical computing companies Vorsprung have created a one of a kind tuning system. Tunes are created based on your riding weight, bike, terrain and rider preferences. The Tractive tune will provide you with greater support, predictability, compliance, and traction over the standard factory tune found in your shock. You will also get more effective use out of your three position compression lever with evenly spaced settings. This upgrade is installed strictly in house only at NSDynamics as an ‘Elite Tuning Partner’ of Vorsprung Suspension.

     
















    Benefits of the Tractive Tune

     
    • Improved support, compliance, traction.
    • Superior stability and predictability
    • Upgraded compression base valve assembly with triple circuit technology
    • More usable 3-position compression adjuster with evenly spaced settings
    • Pressure-balanced valving to provide sensitivity and support without cavitation
    • Low friction Acetal IFP to replace the stock metal IFP which scores the reservoir bore
    • Custom Tractive Valve Tuning System tune selection for each rider based on frame, weight, terrain, aggression and preference
    • Customised rebound valving to replace the stock rebound shim stack (which is non-functional in the Monarch Plus)
    • Nitrogen charged via low-profile reservoir end cap
    • Internal alterations to reduce the typical knocking during direction changes
    • Recommendations on spring pressure and volume spacer alterations if necessary.

    Vorsprung Fractive Tuning System (Fox forks with FIT4 dampers only)

    $130 for pre-configured part alone, or $325 including a full Hyperformance Service and installation

    The Vorsprung Fractive Tune is designed for riders wanting to get the most out of their Fox fork running a Factory Series FIT4 damper. Similarly to the Vorsprung Tractive Tune for rear shocks, the Fractive Tune replaces your stock-standard compression piston assembly with one tailored to your riding weight, style, and preferences. In doing this your three position dial (on top of your righthand fork leg) is converted into a three position high speed compression (HSC) adjuster, and the effectiveness of your low speed compression (LSC) adjuster is improved greatly throughout its full range of adjustment. By providing this specific-to-rider internal tuning and further external adjustability Vorsprung have further improved the capabilities of the FIT4 damper and (with the Fractive upgrade) have made it arguably the best fork damper available.
















    Benefits of the Fractive Tune

    • High performance compression piston for Fit4 dampers
    • Vorsprung-exclusive Online Tune Calculator 'found here' to determine custom compression valving tailored to your preferences & requirements
    • 3 position switch becomes true high speed compression (HSC) adjuster with little low-speed impact
    • Low speed compression adjuster more usable than before - works in all HSC modes
    • Support where you need it, compliance where you don't
    • Allows for linear valving to improve support and adjustability without harshness
    • Available for user-install
    • Compatible with the Luftkappe air spring upgrade kits

    For more information and a complete list of compatibility options please visit the 'Vorsprung Fractive' product page on the Vorsprung website and scroll down to the bottom of the article.

    Sprindex Adjustable Rate Coil Springs - $195ea

    Fine tune your spring rate on the fly with this nifty little invention from Sprindex. Sprindex springs allow you to alter your spring rate (not preload) by rotating the collar/wedge to effectively remove the amount of active coils. By reducing the amount of active coils in a spring the spring rate is increased, and visa versa. NSDynamics is proud to be the Australian distributor for Sprindex springs and have a wide range of stock available. 
    Please see the complete 'Sprindex Website' if you require further technical information.

POM spacers to suit your shock included free with the purchase of a spring.

    Please see the 'SA Racing Springs' product page for more information.


    Custom Valving

    Although reconfigurations of your compression/rebound circuits are usually not needed, sometimes the stock-standard configurations just don't cut it. If you feel like your stock shock or fork isn't working quite as well as it should be NSDynamics may be able to offer custom valving for your suspension.

    Please 'Contact Us' with your requests for more information, ensuring you include bike model, shock model, rider weight and a brief description of what you're currently experiencing, and what you're looking to achieve.
