John Y.wrote a review of Continental Grand Prix 5000 TL Tire - Tubeless on August 19, 2019
Familiarity: I've put it through the wringer
Mixed review. I have a set on a Cannondale HollowGram Si Disc wheelset. They went on tight but OK. They roll really nicely and I'm pleased with them. But, they simply won't fit on my Mavic Comete UST wheelset. I brought them to a shop, and even the pros couldn't come close get getting the tire bead onto the wheel. Since there is no tubeless standard and there are different tubeless ready rim profiles out there, be warned that these tires have a tight tolerance and may not fit your wheelset.
