Mcfk Carbon Offset Seatpost

Availability: Out of stock

Mcfk has elegantly crafted their carbon post with an exclusive layup and molding technique. The asymmetric layup allows Mcfk to utilize a minimal amount of materials to produce a post that is sturdy while maintaining flexibility to damp harsh road and trail conditions. Using a twin bolt and cradle design the Mcfk carbon post allows precise adjustment of both angle and position. The short cradle allows for an extended adjustment range ensuring you get the perfect fit dialed in with little fuss. This post is available in a range of diameters and lengths, and two different finishes. 

In an effort to lighten the post as much as possible Mcfk has removed all excess material. Due to this construction, the post can only be clamped within the reinforced clamping zone. Above the 100mm minimum insertion length the clamping area is 120mm long and can be identified by the change in carbon layup. This means the distance between the frame and saddle rails must be factored in when purchasing a post. The exposed length of post between the saddle and frame needs to fit within the ranges of 100mm - 220mm for 320mm posts, and 200mm - 320mm for the 420mm post. The specific construction of the Mcfk post means that it cannot be cut or shortened and can only be clamped in the reinforced area. Carbon assembly paste is strongly recommended when installing this post.
