i have a thickslick, albeit i think one of the cheaper models. i have allot of tires. like, allot just hanging around that i dont use lol anywho....
the first time i tried this thickslick i threw it on the back of my road bike. and tried it for the first time in rainy conditions. i thought slicks were supposed to be more grippy but my back tire skidded a touch on tighter turns, did it a handful of times. i took it off and put a fyxation 700x23c on the back instead. IMO just from personal experience, fyxations have excellent grip, and feel solid in tight turns. they have wrap around tread but i think whatever material they use just seems/feels grippier.
anywho im giving the thickslick a second chance on the front now that its getting hotter/sunnier. perhaps they just need to be worn in or something i dunno
