Continental Country Tour Plus in 700X35. Put them on my cross bike that I commute on after several flats on the stock Sammy Slicks. When I first put them on I thought I had made a dreadfull mistake. They are quite heavy. But I (over) inflate them to 75 and that really seemed to help them roll faster. Not one flat in about one solid year of commuting, mixed surface and lot's of road debris. I'm happy with them but when I do replace them I'll look for something lighter.
