Think this will be of interest:
Titus FTM Carbon. Frame is pretty lightweight and builds into a great AM bike at around 27lbs!
Tapered headtube. Headset included, which is essentially just the bearings since it's direct mount internal. Size medium (18") with 30.9 seatpost size. 135mm QR rear. 140mm travel. Shock in perfect working order. Bearings working fine but have had 2 years of light work on them.
I'd like £400 delivered, we'll probably haggle over minor marks etc and end up down at £350, so that's what I would like!
Sent this in email too.
