Ray R.wrote a review of Continental Grand Prix 5000 TL Tire - Tubeless on October 31, 2019
Familiarity: I've used it once or twice and have initial impressions
28mm on DT E1800s, replacing Conti 4000 that had approx 6000 miles on them (guess I’m easy on tires). Went on easily with just a smidge of gentle lever assistance for the last couple of inches. Aired up immediately with only a floor pump. Running initially at 70 psi, may need to push it to 75 as they felt slightly squishy. The ride was fabulous. Subjectively felt faster although the weather today was not conducive to pushing for PRs.
