Hi Supergray
I have just moved over to these from rennsports.
I have used 120/180 in the past for fast road, went onto pre-loved 120/190-55 racetecs.
I have always given my tyres some warm-up time, otherwise they will slide, but these have been great - although I do only ride in the dry and warmer weather.
Only 2 brief rides this season
Roll on the good weather
