My seat clamp loosens and my saddle slides back/forth & the nose will tilt all the way down or up. I have been tightening the nut on the post but in a matter of seconds on a short ride, the saddle becomes so loose that I have to walk my bike all of the way home.

Is this a weight issue or a seat post problem?





P.S.

It is a stock post on a 2 month old Cannondale '09 F5

A couple things...
It could be the post. Try some blue loc-tite (thread locker) and proper torque (pretty high on those)...and carry a multi-tool so you can re-tighten the seat and not walk home.

...or just buy a Thomson if you have $75 (retail) or $40 for one off an auction sight.

Thanks for the fast reply.

I just received a multi-tool for Christmas so i will try to tighten the nut more on the post and so what happens. I didn't happen to have it on me tonight, I need to buy a saddle bag that will fit my bike.

A 5mm allen wrench on your multi-tool won't tighten the bolt enough. Just save up for a Thomson and be done with messing with your seat for the rest of your riding life.... Unless you run your bike in to a parking garge when it's attached to your roof rack. Then you'll need to replace it.

It sounds like you have a one bolt seatpost. My personal experiences with those have always ended baddly. Our big butts just need a seapost with 2 bolts that hold the seat on. Thomson (as mentioned above), Race Face Diabolus, and the "Knock-Rated" Titec Posts have been bomber for me.

Usually the 1 bolt posts use a 6mm allen.
I have a few easton seatposts.......2 Vice posts and a new Havoc post. The Vice runs between 30-40 bux. I think the Havoc is a bit more......something like 70 bux....I dunno. i got it on a pro deal so I have no cluse what retail is on it.
I'll get a thompson someday......but the higher end eastons work great for my fat a$$.
