FSA ITC Seatposts employ newest patent-pending design. The SL-K ITC SB0 with the ITC (Independent Top Clamp) design allows for completely independent adjustments of saddle angle and saddle position. This allows for rapid and easy, minute adjustments for bike fitters and end users, to attain the perfect saddle placement. Only one bolt is needed to securely affix the saddle tilt due to 4 tapered-locking grooves between the side clamps and head unit. Furthermore, the side clamps can be switched side-to-side to change the seatpost offset, without compromising the full range of angles. The 20mm offset post also doubles as a -10mm offset. The 0mm offset post also doubles as a 15mm offset. This post allows the greatest ease of adjustability, with a broad tilt range, in two different offsets.
