Yeti Draperwrote a review of Schwalbe Racing Ralph Tire -29in on August 4, 2017
In numbers, the schwalbes sound excellent. They are lightweight, fast rolling and surprisingly grippy. That said, I have never had a schwalbe tire last more than a month. The reason they are so light and fast is because the sidewalls are basically paper, not only that but the material is weak and susceptible to tearing and flats. If you want a tire that performs similarly, and costs the same, and lasts much longer, check out the MAXXIS Ardent Race tires. Trust me, they're better.
