Mcfk Carbon Straight Seatpost

Article number: 018-03-00

Mcfk's original carbon seatpost featured a zero-offset design. This was for good reason; such seatposts are simpler in design and lighter weight than their offset counterparts. Since then, Mcfk's seatposts have been through a few revisions. Until now, the most recent iteration was only available in a minimal offset version. But by popular demand, Mcfk is happy to return this zero offset design "straight" seatpost to their catalogue.

Precision designed and manufactured in Germany, each variant of the straight seatpost has an individual carbon layup schedule to optimize its strength-to-weight ratio. The head of the seatpost features titanium bolts, aluminum yokes and bolt crossbar, and a carbon lower rail support. The blend of these three materials again ensures the best possible weight without sacrifice in overall strength. Since the seatpost rails are supported only on the top and bottom, both oval carbon rails and round steel or titanium rails are supported. These seatposts can be ridden with confidence in a variety of cycling disciplines, including road, gravel, and cross country mountain biking.
