I used to run Q3s. They have good solid feeling at lean and good edge grip, but only got about 1500 miles out of them. Went to S21s then S22s…they were good for about 2500, but the feeling with them is crappy…edge feels really soft and wallowy…they’ve got plenty of grip but it isn’t very confidence inspiring. I’ve got a set of Power Cup 2s ready to mount…I know the mileage will be crap (probably 1000 or less), but they are going to be really fun miles on the mountain roads around here. Bought 200 rear so I get more edge grip at lean.
