is it just me or does the head angle look wrong? seems too steep and a very short wheelbase.

The photo isn't exactly square-on but you're right. I grabbed the pic, straightened it up then measured the angle down the fork and got 74.4° :shock:

The seller does state "the shock is also moveable so you can slacken the head angle", so that's a relief

Looks like the shock is too long (certainly for the position its mounted in). moving it forward would solve it, but.. the piggyback reservoir will prevent this sot he shock will have to be turned round back to front (if it will fit and not foul on the seatpost mast)

looks like its had a hard life,would want to try before buying that one.

Looking at it again, the BB seems to be sitting about 3" above the axles at rest, wouldn't that make it about 15" BB height before sag? :?

a combination of a too-long shock and too-tall fork has that all over the shop

15" b/b is about right! they are tall old beasts but dont fell it when ridden. that one still looks wrong to me,not sure why.

the bb on mine is 18" off the ground

you have to remember depending on the age of the frame it would have been built with a shock that was probably 1.5 stroke and 180mm ish long.
if it has a longer modern shock that will push the swingarm down
and as said the piggyback would not let the shock move to a better position.
