Schwalbe Ultremo DD Road Bicycle Tire
The sound of having to put a double density belt tire on sound like is going to weigh a ton and roll slower! Hardly, this tire does weigh 45 grams more but it rides and feel also most the same as the Ultramo ZX version. So when off season kick in these may be the way to go. Here is why - the HD Ceramic belt it is protected by a complete SnakeSkin fabric. This additional protection works particularly well on the shoulders and side walls. Cuts by glass shards, or sharp flints are effectively repelled. Weight and rolling resistance remain low because of the Triple Nano Compound.
If you want to really take Ultremo AQUA to another notch in performance us the Vittoira latex tubes...
