New Build - Which tapered headset?

ratsbeyfus

Hi

I'm building up a CX bike using a Boardman Frame and Boardman Fork I sourced separately. The original built bike would have come with a tapered headset with 1/8 45x45 & 1.5 36x45 bearings. Do I have to get a tapered headset with the same bearing angles, or can I go for a tapered headset with 1/8 45x45 & 1.5 45x45? Does the bearing angle on the lower portion of the headset match the angle where it sits in the headtube? If so I guess I need 36x45 bearings?

I can find cheap versions of the latter (1/8 45x45 & 1.5 45x45) for approx £18, but not the former (1/8 45x45 & 1.5 36x45)... If I do need the former can anyone point me towards a cheap one?

Thanks in advance for any help

I'd have thought that you would need to use what was originally specified for the frameset, which the BM website says is FSA No. 42 ACB http://www.fullspeedahead.com/products/cyclocross/orbit-c-40-cf-acb-integrated-headset/#
If you just need the bearings try this company http://simplybearings.co.uk/shop/Products-Cycle-Bearings/c4747_4586/index.html

Thanks DJ58 - unfortunately the FSA headset you linked to is the only one I could find previously and is way to expensive. I think I'll have to buy a cheap 1/8 45x45 & 1.5 45x45 headset and swap out the bottom bearings with a set of 1.5 36x45.

Thanks anyway for your help.
