Replacement Spring Kit - Fits 27.2mm ShockStop Endurance SeatPost, +25% Stiffness

Replacement springs are an ideal upgrade if you need a bit more stiffness from your ShockStop Suspension Seatpost. The stiffer springs provide a more topped-out feel, or if you're at the upper end of the weight range and want more support.

• Approximately 25% more stiffness than the standard spring set
• Includes two steel springs (one outer and one inner spring)
• Only compatible with the 27.2mm diameter versions of the ShockStop Endurance Seatpost (both the 280 and 350mm lengths)
