Quiet, pure, unadulterated fun: that's Niner's goal with their One 9 Frame. Handcrafted from Easton's custom-drawn GX2 Scandium, the One 9 delivers a sublime ride through advanced tubing manipulation and Niner's proven geometry. That advanced Scandium tubeset also makes the One 9 beautifully light. And, not only do the rear S-bend chain and seatstays add to that beauty, they also provide maximum horizontal stiffness with no discernible flex at the bottom bracket while still allowing vertical compliance for comfort. Rounding out the package is Niner’s own Bio-Centric bottom bracket that allows for perfect chain tensioning and easy rear wheel removal, even with disc brakes.
