Im always on pavement so slicks make sense to me. They are lightweight and fast. Ive tried larger tires touted for comfort and rolling resistance but these have always been my favorite! The durability and puncture resistance are also first rate!
I wear out 9 of these tires a year on my Scorpion trike. I have been using them for the last 5 years. But, since January 2017 it is seldom in stock and now it is not listed any more.
Did you hire somebody incompetent in the inventory department lately?
I use it on my Scorpion Trike and Gold Rush front tire. I have never had a flat with one in 10,000 miles total. It mounts easily and seems almost as fast as the Durango but does not flat like the Durango.
I have used these Kojak tires on my trikes for years. They are fast, light, wear very well and have good flat protection. I have recommended them to many friends and never received a negative report.
I have this on the front of my Bacchetta ATT 20 with a Kojak 26 in the rear. Smooth ride. Low rolling resistance. I coast faster then my wife on her upright with 700c rims. I've been riding primarily on the street, through tree debris in the bike lane and no cuts or punctures so far. Highly recommended for recumbents
