Schwalbe Ultremo ZLX Road Bicycle Tire
The ZLX is scary fast and I mean fast it also weighs in at a scant 160 grams! it grips like your on rails and accelerates like a indy car, for real! However keep in mid this is a race day type tire and you are also giving up the puncture resistance. This in most likely not an issue if the roads are in great shape.
If you want to really take Ultremo ZLX to another notch in performance us the Vittoira latex tubes...
