Who here has has a high speed blow-out at high speed.

I have had two blow-outs already.....luckily both were on the rear tire and I was going straight at the time. First time I destroyed the rim, but no damge to bike. Second time I only slightly pitted the rim surface because I was going slower.

I am really worried about going fast down hill wthout my Tufo Elites (tubular clincher) because once a regular clincher goes flat there is nothing holding the two edges of the tire togther and it just comes off the rim.

EDIT: Please include information about damaging the rim during the blow-out. Did you scrape on the rails?
