So, my dads swapping his frame to a Singular Swift (blue one), what headset should he get on a budget?
Thanks
Ben

My superstar headsets have been fine, FSA with sealed bearings OK and the new Uberbike models look nice.

FSA always seem to be able to be picked up at a bargain price and I have never had an issue with them. I have previously picked up cheap Chris Kings headsets second hand and had a good long run out of them.

On-One? I've one on my commuter and not touched it in three years

I got one of these Ritchy headsets the other month, so far so good and you can't argue for a tenner The only thing I'm not keen on is the plastic top cap but that's easily changed.

Cheers for the recommendations, but what type of headset will it need? Integrated, semi-integrated etc??

You need to know what kind of headtube it has.

Singulars website says the fork is 1 1/8" and the pictures 'look' like it will be a standard 'traditional' 33.9 dia.
If this is indeed the case you can use the SHIS EC34 / 28.6 upper and EC34/30 lower,

On my Swift I have a FSA orbit (what it came with). Its done a most excellent job overall.
I did have to replace the angular bottom bearing after 4 years of use and abuse but spares readily available.
