Where do you get pinch flats more often? Front or rear?

Never had one on the front.

I usually get them on the rear. When hitting bumps & potholes, I'm usually able to lift off the front-wheel and unweight it. However, this weight is usually transferred to the rear wheel which then gets dragged over the obstacle with your full weight on it... >PINCH< Pffsstttt...Pffsstttt...Pffsstttt...Pffsstttt...

Rear mostly but ocassional front...haven't had one in a while. Best antedote? Pressure...keep your pressures high...especially if you weigh a lot. Also with my Campy wheels I was getting a lot of stem failures at the base. Best fix there was a suggestion from a fellow forum member. Cut a 1 inch piece of old tube...and punch a small hole through both plies of rubber and place it over the stem and then mount the tire and tube. This keeps the base of the stem from rupturing on the hole in the rim...aggravated in particular when pulling off the pump nozzle which loads the base of the stem into the tube. I have very infrequent flatting now with both of the above techniques...hope that helps.

Just had one on the rear. Same deal, I hit a bunch of potholes and lifted the front tire as I passed. My fault and should have known better. I'm thinking that repeated blows to the tires allows air to excape through the presta valve until you get to the point where the tire is low enough to cause a flat. Well, that's my theory anyway....

pump up your tires to right pressure for their size and your weight, and you shouldn't pinch flat short of hitting things of rim denting proportion. I'm over 200lbs, and I cannot recall the last time I got a pinch flat.

The few I had have been on the front. Much reduced by regular tire pressure checks - a pressure gauge is a very worthwhile addition to the bike toolbox.

I only get pinch flats when i hit things of wheel denting proportion, often on high speed descents, and I've blown through both front and rear, and replaced wheelsets as a result. Gerat excuse to upgrade the wheels!

I also have no more problems now that I bought a gauge and inflate to the correct pressure.

What tires/pressure do you use, merlinextraligh? I've got Gatorskins, and like the puncture-resistance, but the recommended pressure is 110 psi (I think), and I can occasionally feel the tires squish down to the rim over moderate bumps. No pinch flats (yet) though. About 215# here.

The last pinch flat I had was a rear one from an unavoidable pothole (too long to explain). I can't remember the last one before that one which wasn't related to poor rim taping.

No intention of beating any dead horses here but the best way to avoid pinch flats completely: Ride tubulars. AHHHHHHHHHH... such a nice ride .

Rear. . . this past Saturday after hitting an unavoidable pothole.

For me, pinch flats are rare. I'm 165 lbs. and I always inflate to the tire's recommended maximum.
