Schwalbe , noun, \'shhh-wall-bee\: the most technically sophisticated tires on the market. The de-facto standard for high-performance tires. [German]
The Schwalbe Ultremo ZX is a race performance tire of the highest order. That's the Ride Studio's view and riding experience. We're in good company because Schwalbe says, "The ZX is the best Ultremo yet." That says a lot because the entire line of Schwalbes is incredible.
Here are some reasons the ZX is one of the Ride Studio's favorite tires - and the best Ultremo ever:
The Ride Studio believes that ride performance is the single most important tire characteristic. If your tires don't ride well, your riding experience will not be the best it can be. Ride Studio defines ride performance as a combination of stability in cornering and descending, acceleration, grip, traction - in all conditions: wet, broken pavelement sandy, and icy.
Schwalbe's RaceStar Triple Compound provides sophisticated contact patch performance: first, the base layer of rubber ensures extremely low rolling resistance; the second rubber compound - the center section of tire - is relatively firm for even faster rolling performance; and finally, the third compound is a grippy material on the edges of the tire for improved off-camber and high-speed turning performance. Schwalbe states that, "No other bicycle tire manufacturer can combine rubber compounds in such a precise fashion in volume production."
Cornering control has been further increased by the ZX's reinforced shoulder; we find that this makes for more stable and predictable handling in all situations.
The ZX also exhibits excellent shock absorption characteristics for two reasons: The reinforced shoulder and the third rubber compound. Ride Studio's experience backs all of this up.
The XZ boasts rolling resistance that is 15 percent lower than previous Ultremo tires! How? Through their RaceStar Triple Compound. It provides sophisticated contact patch performance: first, the base layer of rubber ensures extremely low rolling resistance; the second rubber compound - the center section of tire - is relatively firm for even faster rolling performance.
Puncture Resistance: The ZX employs a patented aramid fiber protection belt that works extremely well. Schwalbe's patented technology is actually a series of 14 international patents for their high density weaving processes. It's what Schwalbe calls their High Density Speed Guard. We've put lots of miles on these tires - and our customers have put on a lot more - with excellent results. The ZX also has a slightly reinforced sidewall for surprisingly durable shoulders. In fact, we did a mountain bike ride on a road bike with ZXs the other day and the tires passed without incident. No flats. No cuts. No damage of any kind. Amazing.
Tire Life: The ZX compound provides a lot of miles per tire, too. Of course, tire life depends on many factors - rider weight, road conditions, tire pressure, and more. We're seeing about 1,600 mile life, on average. That's pretty good, particularly considering the tire's light weight, speed, and grip.
The ZX Line is available in 23c, 25c, and 28c tire width. So, when you're looking for high-performance tires for just about any road riding style, terrain, and weather, the ZX has you covered.
The 23c tire barely tips the scales at 195 grams. Good luck finding a durable road tire at a lighter weight.
The Ride Studio's scientific and rigorous tire changing standardized Gaussian scale shows the Ultremo ZX 23c to be one of the easiest tires to install and remove.
Installation Rating: Our standard tire install tester said, "Fastest tire install in the history of man." Taken with a grain of salt, this translates to something along the lines of, "very easy to install; did not even require one tire lever."
Removal Rating: Very easy. Only one tire lever is required for removal of the tire.
Color & Style
It's a great looking tire. The XZ's make any bike look sharper. Schwalbe offers the ZX in eleven colors. We stock the all-black sidewall; no superfluous tread design. Simple. Black. Classy.
