We've just received the first 2018 Rocky Mountain Slayer and it is the meanest! This is the top-level C90 in size XL.
With carbon where it counts and Kashima everywhere, they left the alloy in the right places for a big bike like this. Rocky's high-end specs have a custom feel to them, this one having a RaceFace cockpit and Flow wheelset. No house brands on this bike, it's spec'd in the same way you'd build your dream bike.
This XL weighs 13.61kg! Take a look.
