I haven't yet..... (knock on wood)! The inner bladder or tube helps cushion the blow against the rocks when hit straight on.

Much greater rim protection (even at very low pressure) than running a heavy duty tube. I bent both rims on my new gasser (in 2007) within the first couple months running standard tubes. After changing to tubliss in that bike and later my 2011 gasser I've never dented a rim again. I always run less that 10# pressure in front and my rear is usually 6 or less. On my 300 the rear was probably 0-4 pounds more often than not.

I just tried it this weekend with a tubliss at 3 psi for a race in very diverse terrain with everything from deep silt that I buried the bike past the pegs in, to clay mud with rocks, roots, and lots of tree crossings and steep hills. I have to say that I was very pleased with it except for braking. Seemed strange because never had any problem with wet roots and steep climbs finding traction, but trying to brake was a nightmare. Going down some of the hills got a little sketchy because even touching the brake would make the rear skid and slide out, had to rely on the front to do almost all the braking even on the flat. Maybe the rubber is too stiff to bite into the hard pack. I am going to try sipping and if that don't work then I am going to a different tire because if i ever lose my front brake lever I don't think I could be comfortable finishing the race.
