i just got conti ultra gatorskins because i ride around 20miles a day on a 82 or so schwinn world sport with 27x1 1/4, they seemed to be the best reviewed tire in my size and it is a world of difference over any other tire i've ridden the same size, i like it, i can't speak to much on the durability of them because like i said they've only been on a week but they seem to be awesome at this point, definetly worth the money so far
