Stumpjumper 15/Evo Link (2025-current)

Our link for the 2025 to current Specialized Stumpjumper allows you to dramatically alter the leverage curve of the bike, essentially getting you a whole new bike! With the stock shock on a 29" bike, it boosts travel to 152 mm and a little more than doubles the amount of progression. The results are even more dramatic on frames with a 27.5" rear wheel. Our testing with the stock shock has found that this allows us to increase bottom out resistance without reducing the bike's ability to handle chatter. Even with a special shock, it is very easy to overwhelm 12% progression. Not to mention 4% on mixed wheel bikes. This also opens the door to other shock options, such as coils, that are poorly suited to the stock link.
