I'm 6'5 and 185lb. I'm not that heavy, but I am tall and have to stick my saddle pretty far back in the post to have it fit(usually as far as the safety marks allow..used to slide it further). I also haven't had a saddle last more than a year. I've tried various brands, but they all bust within 2-12months. Also, I bust saddles whether it's road or mtb riding, it' sucks
I've broken rails, but usually it's the contact between the saddle and rails that fails.
Having said that, I found a fun looking post at http://pricepoint.com/detail/16675-2...r-Seatpost.htm and I'm wondering if any of the other riders with lots of force on the saddle have tried these(or something similar)? I'm used to the saddles busting, but I've never busted a post(tho cf ones bend noticably under me). Do you think this post would be safe for me to ride?
