I did have them on my Karate Monkey, but swapped them out for some 37c Contis. They look great, but were too heavy for my single speed build. For one, I think I had too tall of a gear and the Big Apples are larger in overall diameter so that added to the tall gear issue. It also takes a lot too get them up to speed which isn't good for my stop and go, city commute. Couldn't fit fenders over them, but I think the New Planet Bike 29er fenders are out now which will work. YMMV.
