Detail
Mcfk's seatposts are among the very lightest available and feature solid, German-engineered construction and impeccable finish work. For riders that require a rearward saddle position, this seatpost satisfies those biomechanical requirements while adding a weight penalty of only 10% (compared to Mcfk's zero setback seatpost). Unlike other seatposts of similar design, Mcfk's lower rail clamps offer a much greater contact area, allowing greater security and support for delicate carbon rails. Cosmetic options include 3k weave and unidirectional, both in high gloss finish.
Mcfk seatposts are manufactured in Germany, and feature a two-year warranty against defects in materials and manufacturing.
Ordering
Mcfk's setback seatposts have been weight optimized by limiting the clamping range of the seatpost collar. The following table expresses acceptable seatpost extensions, measured from the center of the saddle's rails to the point where the seatpost exits the frame. Improper installation of this seatpost will void the warranty and can cause seatpost failure and/or serious injury. Please feel free to contact us for compatibility questions.
| Length | Extension Range |
| 300 | 150-210 mm |
| 350 | 190-250 mm |
Installation
We highly recommend the use of a carbon assembly compound (such as Tacx Dynamic Assembly Paste) on the seattube/seatpost interface to limit the clamping torque required. A torque wrench is highly recommended as well. Mcfk recommends a maximum seat collar torque of 6 Nm, and a maximum rail clamp torque of 4 Nm.
