Saracen Zen headset = baffled.

I've bought a second hand Zen frame (2011 - 3) withought a headset and am slightly baffled as to what I need. I need to fit standard 1 1/8th steerer forks.

As standard it came with 'FSA gravity dx pro' to fit a tapered steerer fork in the tapered headtube. Googling that headset gave me the following info;

'1 1/8th" 36deg/45dec acb upper
1 1/2" 36deg/45deg acb lower
For tapered 50mm/57mm OD headtube'

I'm pretty certain that the headtube is actually 44mm/49mm though, hence the confusion. I popped into my new lbs with the frame to ask for advtice but the first guy I spoke to had no idea about headsets, another guy got involved but gave me a choice of 1 headset and the mechanic was too busy to speak to me.

Will this fit? http://superstar.tibolts.co.uk/product_ ... cts_id=425

Is there anything I should be looking at as an alternative?

This is what the headtube looks like

OD is outer diameter - what is the internal diameter of the headtube at the ends?

It needs to be measured and confirmed.

How did I miss that?! I measured it (with a ruler, as that is all I could find at work,) and was 44mm top and looked slightly over 49mm bottom. The lbs wanted me to book it in and leave it with them just to get it measured, so I didn't bother!

Worth investing in a pair of calipers for accurate measuring. They don't have to be expensive, like these for e.g.
