Other Rocky's, Kona's, Klein's etc. XTR, Race Face, Chris King, Profile. Good climbing and excellent decents. If only the ass holes at the dealers would warranty the parts i would have no complaints. I no longer seem to need to be in shape for riding, as it has quite a large weight difference from my old bike.
Frame geometry is great for climbs and maneuvering, very stiff.
Looks great, and works great. Rocksy Mountain Vertex.t.o have Very Short Top-Tube. There are none. The company, the people in the company, the warranty. Fine until you call on the warranty.
