Cane Creek eeSilk+ Suspension Seatpost

The Cane Creek eeSilk+ is a premium lightweight suspension seatpost designed to improve rider comfort on long rides and rough surfaces. With up to 35mm of vertical compliance, it reduces road shock transmitted to your lower back and sit bones—helping you ride longer, faster, and more comfortably.

Featuring a parallel-link design, it maintains consistent saddle height and angle throughout travel, ensuring a smooth and stable pedaling experience without bobbing. The post uses swappable elastomer inserts to adjust stiffness based on rider weight, and changes can be made externally in under 2 minutes using only 3mm and 4mm allen keys.

Available in carbon and aluminum versions, and compatible with over 20 seatpost adapter sleeves to fit a wide range of bikes.
