FrostBike 2013: Hands On with Schwalbe’s new Ultremo ZX Tubeless Road Tire
Road tubeless is a technology that has a lot of folks excited, yet the roll out has been a bit slower than expected. With Hutchinson more or less leading the way, for a while any other tires were simply rebranded Hutchinsons, however other companies seem to be closing the gap and bringing their own tires to market. Schwalbe happens to be one of those companies as they offer their new Ultremo ZX Tubeless road tire which was first introduced at Interbike, and is now about to enter the wild. Billed as the lowest rolling resistance tire that Schwalbe makes across the board, the 700x23c tire is apparently the fastest tire they make.
We threw it on our scale to test out the claimed weight, after the break.
Keep in mind that this is a pre-production sample, so 309 isn’t terribly far off from the claimed 290g.
