The Flatforce Stem is a brand new stem from Syntace that has been designed to fit the gap for the 650B mountain bikes, which are Approx. 25mm bigger & even some 29'' bikes. With the new Syntace Flat Force your handlebar will remain in the same position you've been riding with when you convert to say 650B instead of having to put up with a now raised bar height. It is made from high strength forgeable 7075 T7X alloy with a completely hollow construction allowing it to weigh a mere 116g (60mm size). The Flatforce can be combined with bars up to 800mm wide & still provide stiffness & strength that would normally be found in stems over 200g. Another feature of this stem is the new low 3:5 boom tube, with less than a 25mm stack height it means you have the most effective knee, back & chest protection. Available in Raceblack with a 77mm length only.
