That's a Raleigh Montage. I had a Raleigh Mirage for my first bike! They're late 80's I think. Rims, obviously, aren't original and it looks like the cranks are uprated as well.
Montare was the gary fisher number, montage was the raleigh name. Sat fairly high up in their ranks of M bikes: Mustang, Maverick, Magnum, Mirage, Montare wasn't it?
Looks to be the same size as my first proper mountain bike, a Magnum (I'm 5'7", but my parents had high hopes obviously...)
as im pretty much a die hard raleigh fan. ive ridden it around the block and i think im pretty much the right hight? (6ft 1) think it should clean up realy well. theres no rust on the frame just loooooaaaddds of dust :?
