Looks like an octalink xt crank and a superstar ring??
Any more info?
Probably Middleburn cranks looking at the silhouette.
I'm guessing shimano lx m569
Most of the Fern bikes have a painted (or anodised?) Shimano Dura Ace FC-7402 crankset, with a 116 mm (probably Neco- cheap but very good) sealed bearing. JIS tapered. Which gives the bike a 140mm Q factor and a 46mm chainline.
