Only used it in earnest once but no complaints so far. Dealing with Merlin Cycles is a real pleasure. They have great patience with us older, and more forgetful, cyclists :)
Great racing tyre for UK conditions. I have been using this tyre throughout 2018 and have never suffered with any lack of grip no matter what the conditions. Inspires confidence in the corners which let's you carry more speed and get better lap times.
A very good Tyre at a reasonable price, it rolls very well, fast and light, would recommend for the trails
Love the tire. They were a bit tricky mounting on DT Swiss wheels, but after stretching them with an innertube overnight, with sealant painted on the bead, they sealed nicely.
The ride is great but they were by far the hardest tire I have ever mounted on my Roval Control SL rims. Broke 3 tires levers.
Light and fast rolling. Tubeless setup was easy as always with Schwalbe.
Bought a pair to replace my stock tires. The grip is superb and superfast rolling! Each tire weights aroung 610g. Extremely fast and reliable. This model has not arrived in brazilian stores yet. Great purchase!
I've been using the Racing Ralph / Rocket Ron combo on my XC bikes for the last 4 years. While I should use them just for racing, I'm lazy and leave them mounted year-round, so they wear down after one season. I'm not expecting more from this new Addix Speed compound, but at least the tire is sporting a handy red stripe to remind me what I was running. The measured weight on this tire was 608 grams, which is not bad as I've had the RRs vary 50+ grams more.
