I think I can shave about a kilo off my bike for the ride. The Marathon Plus 38 i have on the rear is listed as 990 grams and the double kickstand is like 550... The +'s have serious rolling resistance as well so that might be an bigger improvement than the weight.
So event tires it is.
Likely move my 38 marathon from the front to rear and perhaps get a 32 or 35 for front...
I used to love Gatorskins, but I think they top out at 28's...
