Choosing the right Sprindex

Selecting a Sprindex for your current coil shock

Consider which of the categories you fall into:

  1. Your current coil seems a little too stiff and you are not quite getting full travel. Choose a Sprindex with the highest end of the range at or just below your current coil. For example, if your current coil is 450, choose about a 400-450 Sprindex.
  2. Your current coil seems a little too soft and you occasionally bottom out.  Choose a Sprindex with the lowest end of the range at or just above your current coil. For example, if your current coil is 450, choose about a 450-500 Sprindex.
  3. Your current coil is way too stiff. Choose a Sprindex with the highest end of the range around 25 to 50 below your current coil.  For example, if your current coil is 450, choose about a 350-400. 
  4. Your current coil is way too soft. Choose a Sprindex with the lowest end of the range around 25 to 50 above your current coil. For example, if your current coil is 450, choose about a 500-550.
  5. Your current coil seems to be very close to your ideal for most riding conditions. Choose a Sprindex with the your current coil rate somewhere towards the middle of the Sprindex range.

Note that sometimes the rate marked on your current coil shock may be up to 5% or more off of reality. The only way to know for sure is to have the rate tested.  As a point of comparison,
 you can use our spring calculator. 

Spring calculators do not take into account your exact bike suspension, the way that you ride, body position, trails you ride, and so on.  They can be a good guideline starting point.

There are three different Sprindex lengths and strokes available, and each Sprindex coil can be adjusted through a certain spring rate range.  Be sure to use the correct included adapter as described.  Make sure that the spring length fits on your shock and that your maximum shock travel is not more than the specified Sprindex coil travel.

Customer Reviews

"The shock is fantastic but this is a real game changer. I was in between 550lbs and 600lbs in spring rate and was recommended this by one of the staff (Greg) as a way of giving me options. So far, I'm bang on the spring weight we discussed but knowing I can change it whenever is such peace of mind."

"Expensive for what it is and the difference between its lighter setting 610lb and it’s heavier setting 690lb is really not that noticeable so much so I’m a tad sceptical. "
