I felt compelled to warn others of my experience with the U.S.E. titanium seatpost and the f'in nasty injury it caused me. This was with the original 2-bolt clamp design which has since been revised, but the "new" one-bolt design looks as flimsy as the original. Short story:

I bought the U.S.E. seatpost for my Surly from an online parts retailer that I've used for years. Never had a problem with the post until one night riding home when I briefly sat up in the saddle and rode no-hands for half a block. The next thing I know I'm falling off the back of my bike and miraculously end up in a standing position watching my bike wreck in front of me. Naturally, I'm like wtf just happened? End result: busted clamp, large bruise/gash on left thigh and a f'ckd up new rear wheel (I fell on it). I pulled the f'in piece of crap post out and rode home for the better part of 12 miles with no saddle. Yes, my quads burned, but not as much as the silent rage that seethed within me.

I contacted U.S.E. and sent them photos of the broken clamp (below). I calmly informed them that I rode daily on their *new* seatpost for less than 6mos. It was installed and used properly. At no time did it creak or give any indication that a failure was imminent. They apologized & offered to replace it with their MTB Sumo model through the retail shop I ordered from. I said 'no thanks'. I'll accept a refund but never confidently ride on their crap again, thankyouverymuch.

U.S.E. = ultimately sh1tty engineering
