Faster and even faster. We challenge ourselves. That is why in the "ZX" we installed our latest developments, RaceStar Triple Compound and HD-Speed-Guard. Both components perfectly combine the requirements of competition racing cycle tires. That is exactly why the ZX is the best Ultremo ever!
The question is: On what rim will they fit?
Some samples on their way! Will post if they fit on my AlexRim30
The Ultremo ZX is narrower than the Durano.
Will update when they arrive.
