FYI... the magic aero properties go to hell long before you've used up all the tread. So if you want to race on the GP4000S, it's best to use new ones. Also the aero goodness is mostly for high yaw, which may not describe your conditions. I still think the 20mm SS for narrow rims, and for wide rims the 22mm Attack or 23mm SS or maybe even the 20mm SS are the fastest choices for *racing* tires... for most conditions.
I've used the same set of gp4000s for the past two seasons.....18 races.....close to 400 race miles.....mostly OLY and a few Sprints. I like them......and have no problems.....flats, etc, using a Zipp 900 on back and Zipp 404 on front.....23mm on both (Cervelo P4). Pretty much only use bike for races.....maybe have 500 total miles on them (use another bike for limited road training). Are you saying I would still benefit by getting a new set before next year's schedule starts with this kind of mileage on them? And to others who use these tires......how often do you change out and do you notice a difference?
PS.....was actually thinking of trying the Attack/Force 22/24 combo next season just to experiment......any new thoughts/advice here?
