the 2004 frames had a different front shock mount bud...yours is definitely a 2000 or 2001 at the latest as they changed the front shock mount a few times as the frames evolved. Its a 16" patriot LT..long travel...that model was usually 5" travel but your's having no v brake mounts dictates its a lt.....it has a fox vanilla rc rear shock with a measurement of 190 x 57mm stroke instead of the standard 50mm stroke...due to the leverage ratio, this gives you the extra inch of rear wheel travel..if its the standard spring then it'll be 450lb. on the 2004 the front shock mount was welded between the downtube and the toptube(ive had a few) whereas yours hasn't(also had a few lt's) also...the 2004 bikes used a different shock...normally 5th element coil/manitou swinger 3 or 4 way coil or air
