I heard this creaking sound the other day while riding the diSSent. At first I thought it might be the headset because I have been down that road before but I then I realized that it was only happening while seated. I got off the bike and inspected the saddle upclose only to discover that I have a bent rail. I have never seen this before.
I fired off an email to J&L Distributors, the importer for Origin 8 products and this is what they told me to work with the shop that I bought it from. Dropped it off last night at the Bicycle Goodie Shop so lets hope they come through.
