The Easton EC70 ISA Seatpost is an ideal upgrade for road cyclists and mountain bikers looking to achieve a precise, stable riding position using high-quality materials. Featuring lightweight unidirectional carbon construction and patented Independent Saddle Adjustment (ISA) technology, this post excels at allowing riders to fine-tune saddle tilt and fore-aft position without compromise. While it offers superior adjustability and security, users should note that the dual-bolt system requires a slightly more methodical approach during initial setup compared to basic single-bolt seatposts.

This model is 27.2mm in diameter and 350mm in length.
Yes, the EC70 ISA is designed for both road and mountain bike applications, provided the frame size is compatible with the 27.2mm diameter.
The post features a 20mm head offset.
Standard hex keys are used for all adjustments, though a torque wrench is highly recommended for safety and precision.
The minimum insertion depth required for this seatpost is 80mm.
Ensure both pitch adjustment bolts are tightened evenly to the recommended torque specification using a torque wrench.
Clean the seat tube and post thoroughly, then re-apply a fresh layer of carbon-specific assembly paste to increase friction.
Installation requires a standard hex key set and a torque wrench to ensure carbon safety. When setting the post, ensure at least 80mm of the shaft is inserted into the frame; exceeding the maximum extension mark will compromise the structural integrity of the carbon. Always apply a thin layer of carbon-specific assembly paste to the seat tube interior to prevent slippage and oxidation. For the ISA head, ensure the dual bolts are tightened in small, alternating increments to prevent binding or uneven pressure on the saddle rails.
