We all benefit from comfort, but all too often, it comes at the expense of performance. Not anymore. With the Ruby Comp, you get a next-level comfort from a design that's nothing short of revolutionary. The frame is among the lightest that we've ever made, and it's been constructed from our superlative FACT 10r carbon fiber. Its stiffness levels are also off the charts, and compared to the SL4 iteration of yesteryear, you'll experience a whole new, faster, and more efficient geometry. Through some engineering sorcery, however, we've managed to keep the same fit, feel, and position that we've all come to love from the SL4's Women's Endurance Geometry.
