Mcfk Seat Post - Offset 5mm - 30.9mm UD Matt

One seat post, many possibilities

The offset of a seat post is not as easy to quantify as may seem. If you focus on what is essential you will find quickly that the offset is limited only by two components. One is the clamping plate of the seat post and the other is the length of the seat rail. The short clamping plate provides a wide range for seat adjustment.

Outstanding performance

• Mcfk seat posts are optimum in terms of durability, comfort and weight. At present, hardly any post uses carbon as material more efficiently than these posts do.
• Mcfk uses complex sophisticated asymmetrical layer design of varying diameter, length and range of adjustment. Only this development effort and the high-precision manual manufacture, at the site in Germany, guarantee the high stability, the low weight and the exceptionally outstanding manufacture.
• You can install seats both with round stays or highly oval carbon seat rails with a high adjustment range on the 2-screw clamping mechanism with high-strength aluminium clamping parts and high-precision, black carbon rocker and black high-precision titanium screws.
• The clamp is of sufficient stability not to fail in excess load situations and the long seat support places less stress on the seat rail.
• Mcfks seat post is Di2 compatible! All models fit to the Shimano battery SM-BTR2. For the clamping Mcfk recommends to use their own battery holder, which can be obtained in the online shop. Please make sure to choose the correct seat post diameter.
