I had a couple of road morphs; one fell off when I was leading a ride, and then, when I got my Kuota in 2008, it didn't fit the frame. I guess it was fine for a frame pump. I've never been comfortable changing a flat, won't go into that, but I had to start carrying CO2. I now have Gatorskins on both of my bikes and I haven't had a flat in 3-4 years, the last time being when I was on a ride with Hirakukibou.
