Thanks for the comments guys
mtbmaniac - you are spot on, it should have a zoom long layback post but it was not there when I bought it, does anyone have any idea where I can get one?
I'm also after a picture of the original decals from the '94 Diamond back catalogue or wherever if anyone can help?
It was an A5 portrait size catalogue if i remember correctly.
There are lots of '93 decal pictures and I have the 93 catalogue at home but the two years are quite different.
*edit* just found a picture of a 'reasonably stock' '94 with a scary bloke leaning on it!
