Unless you’re a bike beaster a normal headset is fine, although if there is a problem Nicolai will say you should have run a deep insertion headset as instructed.
For a deep insertion headset fit a good one as it’s something you only ever want to do the once. The Nicolai FET set is stoopid heavy, the CK steelset is lighter but still heavy, but my money would go for an Acros which is lovely (if my frame didn’t have the 1.5). Seriously, if your ordering new get the 1.5 headtube – ideally to allow the Cane Creek adjuster thingy and for future proofing. If it’s a bargain frame think how hard your likely to be ragging it and be honest as to if you will need a strong headset… and then buy the Acros because it’s relatively cheap, very light for what it is, will give peace of mind, and is available from the nice bloke who is Richard at Gravity Sports (or from Jamie at Balfa).
Re TLR’s pedal strike… he is the only person who suffers from this… I’m running 30% sag front and rear and it bothers me not… whatever TLR is doing wrong he is doing it wrong to himself 😀
