I've used Hutchinson Scorpion Tubeless and thats about it. I'm new to this tubeless tire thing. I really like it on the front tire, it seems to work well. I'm on a Cannondale Jekyll 1000. The rear tire as already worn out and it was replaced with a Michelin XL S UST Tubeless rear tire. The front is still the Hutchinson Scorpion. I heard good things about the Michelin XL S UST Tubeless. What's your take on tubeless tires?
