The 2009 K-Force Light seatpost is a one-piece carbon monocoque design with a two-bolt chromoly/stainless steel head that makes ﬁne-tuning the saddle angle a cinch.
Once in place, it does exactly what you want a good seatpost to do by holding everything ﬁrmly without any complaint or ﬂex. The K-Force is available in 27.2, 30.9 and 31.6mm diameters, and with a setback (distance from the centre of the post to the middle of the clamp) of either 0, 25 or 32mm.
All are 350mm long. Our 31.6mm model with 32mm of setback weighed a reasonably light 251g – all other versions are slightly lighter.
