i've ridden the volante se's on my conversion a good 5-6 months and i can't complain. had one flat, but i think it was because i didn't check the tire pressure (locked up, came back in morning and tire was flat). they are a very nice, cheap, and durable tire. i have the rubino's on my road bike but cant really equate that to fixed riding. they have held up pretty well to abuse but the bike isn't ridden every day. and gatorskins on the track bike, which i like.
