tension bolts breaking

I had a B17 and the front bolt broke on me and I don't have any idea how. I was just going to lube the front bolt on my Swift and that bolt has a pretty good bend in it. I don't really think I'm that abusive and I take pretty good care of it, but for some reason this keeps happening. I bought a new B17 and I don't have any problem with it after 2000 miles. Anybody got an idea. I was told that if you lift the bike by the rear of the saddle it could cause this. I have the saddle on a 20# CF bike and I really don't think that would cause it. I have a Look bicycle with a Fizik Aliante on it and that bike has 3000 miles on it and it doesn't have a problem and it's treated the same as my other 2 bikes. Anybody else have this problem and what could be causing it.

I call BS on that one. If picking the bike up by the saddle could bend or break any part of the undercarriage, it wouldn't last 50 yards with somebody riding it. More likely it's just poor QC, which fits with the rep that new Brooks saddles have. I've got a probably 35 year old B17 on my daily rider, and though I have to hold the tension bolt by hand when adjusting it, there's no sign of ANYTHING bending. (BTW, I'm a 190 lb high-mileage (8-10k mi/yr) rider).
