Let's revive this old but useful thread. By accident I just bumped into (and bought) a nice 1995 Blizzard. It's an 18.5" with Rocky Mountain stamped dropouts, but what's interesting is the serial number: B0070. Quite unusual for this year. I'm glad with the frame and the bike, nonetheless, but am puzzled my this serial number that deviates so much from any post '94 Rocky I've seen here on the forum.
Just added what I believe to be a 95/96 Altitude to the registry in hope of some help on its lineage. The serial number on the BB reads RMA096. I bought it from a secondhand shop in cosmetically rough but serviceable condition. It's covered in Grip Shift decals and never appears to have been graphic'd as an RM. It has Ritchey drop outs and the same paint as a 95 Team Only.
