FAQ
How long should I expect the ShockStop elastomers to last?
The elastomers should last for several years, but the exact lifespan will depend heavily on use and environmental conditions. We spent a long time designing the internal mechanism and the elastomers so that we would not exceed loading conditions that could internally damage the elastomers. In addition, we have done a significant amount of cycle testing and measured changes in stem deflection under load at regular intervals and found no drop off in performance.It should be noted that the elastomers will "break-in" slightly as they settle into place, so you might notice the stem response softening slightly after a ride or two. This behavior is to be expected, and once they are broken-in the response will stabilize.
