Schwalbe One have replaced Ultremo .. I am currently using a pair of 25c since last couple of thousand miles perfectly good tyres; light; roll nice; grippy and I've had 2 punctures both pinch flats due to wrong air pressure .. tubeless compatible too if you are into that sort of thing
The Ultremos look a bit gash though.
The vittoria Diamante pro light seems light at 170g with a puncture belt (how effective it is, I have no idea)
