So i've got hold of a Marin frame and im planning on doing it up as bit of a project.

This is the frame: ... &Type=bike

It came with nothing but the headset and bottom bracket, but they need replacing, at the moment it has a 1 1/8 Threadless Headset and a TruVativ Power Spline Bottom Bracket ( ... -prod21496).

Now as far as i know, the bottom bracket can be replaced with whatever a new crankset needs (Probably HT2) aslong as the widths and diameter match?

But the headset is where im struggling, does it have to be a Threadless headset or can it be a different standard?
