One direct result of my being on these boards is that Schwalbe later this year will start producing 700x28 Marathon Supremes.
This is great news! Thanks, Kojak. Now if only I could think of an excuse to buy a new set of tires. I already have 2 sets of marathon supremes, 1 set of marathon XRs, 1 set of marathon winters, 1 set of marathon racers, and 1 set of big apples. 12 tires for 3 bikes (plus a spare wheelset). As you can tell, I'm a happy customer, but it's going to take me a few years to work off what I have.
Any idea what the weight of the 700x28 will be?
