2002-2004. I sold my 2000 Blizzard and got a 2002 Rocky Mountan Hammer. Still a cr-mo frame, but this thing was so, so much better because I upgraded to to Shimano 555 disk brakes immediately. I ended up with a lot of cool parts on this that I got from shadowy people for cheap. Mavic crossmax XL rims and a fox Talas fork were simply amazing upgrades, but not as game changing as disk brakes. I rode this until 2004, when I custom built a Santa Cruz Blur.
