After a few mishaps (after all 3 tires per season, all edge damages ... for the glory of the Ultremo ZX: the tread battered - but no breakdown damage, perhaps a little unlucky was there) with the rather sensitive Schwalbe Ultremo ZX I looked around the end of the 2014 season after something more resistant and have come across during my research on the Conti. He is something visually simple, but robust and made harder for urban use. The tire is of course not so easy and smooth, we-the Ultremo ZX. Eben good for training and for longer spontaneous trips with less than ideal road surfaces. Mint concentricity and sitting on the rim are good qualities that I can confirm. He walked a little (by design) tightly over the rim flange. A little dish on the bead managed as remedial during assembly. He is also slightly profiled and the flanks are running a little stronger. He gets along well with the standard Road Tube Schwalbe. So far, he delivers what he promises. More can be said only after the 2015 season. The self-presentation of the product by the seller buy stimmt-!
