Very early to tell as I've just got back on board after a few years off and am taking things steady for a while, however, even in the current cold conditions they warm up nice and fast and seem very stable in the corners.
Best thing so far though is the way they track over those horrible expansion joints that cable laying companies love to stick in the middle of what used to be nice smooth country lanes. My old bike would hit these and fidget all over the place. Not sure if it's my ss or the tyres, but it's almost like they are not there.
