Race Face SIXC Seatpost

It's carbon, it's Canadian, it weighs less than 200 grams, and it's worthy of downhill that most riders would have to walk or just tumble down. The RaceFace SIXC Seatpost is all of these things, thanks to advanced design and the unbelievably high standards that RaceFace products are forced to live up to. The SIXC uses a special leading edge composite carbon fiber layup to achieve incredible impact resistance and a ridiculously high fatigue threshold. Not only is it tough and lightweight, it's also ingenious with a clamp system that allows tilt adjustments and foreaft adjustments to be performed separately. The clamp is only compatible with I Beam saddles, not saddles with traditional rails.
