Summarized by Shop
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.
