I've just bought a pair of Schwalbe Marathon Supreme 26"x2" today for an old Bridgestone mountain bike that I've customised with drop bars ....
I really wanted Compass Rat Trap Pass .... after reading your post, I'm sad now and should have bought the compass tyres
Oh well, next time ... when the Schwalbe's need replacing, I will get the Rat Trap Pass .... only thing that concerns me is the puncture resistance (I commute 40km per day, but it's only on Asphalt/tar roads with a few potholes here and there)... I hat punctures and loose money if I'm late for work
