The tire arrived 3 days ago and I've only logged about 20 miles on it. It rolls smooth and fast. I can't speak to it's durability as yet, but I love it right now. Makes my old Puch Meteor Luxe feel like a real speedster. Because its' so stiff it was a little hard to install and had me wishing for a 3rd hand, well worth it though. I thought, This thing is going to ride like its' made of granite. Rides like a dream.
