Gregorius Perriwrote a review of Schwalbe Racing Ralph TL Ready Tire - 29in on May 14, 2014
Familiarity: I've put it through the wringer
This is a competition race tire. It is meant for racing, but it is more durable than the Rocket Ron or other super light race tires. So although it is light, it isn't ultralight. I love the tread pattern and it grips well on a variety of surfaces, and very fast. It isn't a great mud tire, but that isn't what this tire is for. (It is rare to be racing in mud). They do make a snakeskin version of this tire if you want more durability, but of course it adds some weight. I did have one puncture that wouldn't seal using this tire during a race in Park City last year, but it wasn't on a sidewall so I'm not sure the snakeskin version would have prevented this (I just impaled the front tire on a ridiculously knife-sharp like rock). I usually go through a set of these tires about every 3-4 months, and that is riding 2-4 times a week for about 1.5 hours.
