SPRINDEX ALLOWS FOR TOOL-FREE, EASY ADJUSTMENT OF YOUR COIL’S SPRING RATE.
Adjusting your shock’s spring rate can profoundly improve your bike’s handling and suspension. In fact, you may find yourself using different spring rates for different trails, depending on the conditions and type of trail. Or you may increase your spring rate for long climbs and decrease it for down hills.
- Adjustable base spring rate with a progressive finish
- Price includes all tax and express shipping to your door
- Includes spring, adjuster, and 5 performance adapters
- Lightweight (highest grade steel allows less material)
- Available in 5 spring rate range options

FEATURES
No expense was spared on the materials or manufacturing processed used. The coil itself is made of super high tensile spring steel similar to “lightweight” springs (which is why Sprindex is lighter than regular springs) in order to handle the stress of the system when adjusted to its highest spring rate setting, as well as reduce coil mass. The Sprindex assembly is made of glass reinforced polymer. The 5 included adapters are made of slippery Delrin.
Spring rate is the force required to move a spring a given distance and independent of preload. For example, a “400 lb/in” spring requires 400 pounds to move the spring 1 inch and 800 pounds to move a spring 2 inches. Preload is how much force is required to start moving the spring. Sprindex is patent pending in many countries.
Follow your shock manufacturer’s instructions for preload amount and sag and other shock adjustments. Do not preload your Sprindex more than 3 turns and 1 to 2 turns is preferred.
Your Sprindex coil behaves like a regular coil that has a spring rate the same as your adjusted Sprindex spring rate. Adjusting your Sprindex does not change the length of the coil and so does not change your preload. Preload is adjusted normally and with the threaded ring that came with your shock.

LIGHT DUTY TRAIL TIRE THAT ROLLS FAST IN DRY CONDITIONS
The aggressive tread combined with a high volume casing make the Ardent a great front and rear combo on a trail bike, or as a rear tyre on an enduro bike. If using on an enduro bike, match it up with either a Maxxis Minion DHF, DHR or Highroller 2. The ramped centre knobs offer great rolling speed while their shape allows them to be very effective at braking and climbing. The Ardent also offers oversized and stepped side knobs for multiple gripping edges when cornering.- Tubless Ready

Bigger, grippier, lighter and as tough as ever. The Penthouse Flat MK5 pedal is here!
After two years of development and testing the MK5 Penthouse Flat is here. Retaining our signature toughness, the MK5 is the lightest and grippiest Burgtec pedal to date. We did this by not only increasing the size of the pedal platform, but also how concave it is alongside reducing the diameter of the pins and adding the most wear resistant internals on the market.
Riders want the derailleur to do its job shifting on command, whether under climbing load or the stage finish.

The strongest system is a chain with no weak links. Eagle chain links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. And it’s also the biggest contributor to the ultra-smooth, precise, durable and quiet performance found in the 10-50 and the new 10-52 tooth cassette and X-SYNC 2 chainrings.
