Saddle Slippage(5 posts)

I've got a recurrent problem with the stock saddle on my Gary Fisher Tassajara. It's a WTB saddle; I forget the model name. Comfort isn't the issue; rather, the problem is that the clamp doesn't want to hold tightly -- the consequence is that when I hit a bump the saddle tends to pivot vertically, and depending on where my weight is when it happens the nose goes up and it becomes uncomfortable, so I have to stop and adjust. The clamp bolt is tight and, although I have not measured it with a torque wrench, I can't believe it's off by much from suggested torque.

Any ideas? Is this just a perpetual problem with saddle clamps, or is there a fix (including a replacement saddle)?

Thanks.
It's not your saddle, dude.Kerry Irons

It's your seat post, or more precisely your seat post clamp. Somehow it's not clamping your saddle tightly enough, and you need to figure out why. Try marking some exposed clamp part and the saddle rails with an indelible marker, and then see where things move when it gets out of whack. This is not a common problem so you need to do some discovery of the cause and mechanism. It seems that you might have some part that is not put together right such that when you tighten the clamp it is bottoming out on something before it can apply full force to the saddle rails.
You have the Bontrager post, huh?russw19

That's part of the problem. The stock Bontrager seatpost on that bike isn't very nice. If you want to buy a new one, a good design is the Thomson post. It's light for an alloy post, very strong (perfect for off road abuse) and not too expensive. But the best part is that the clamp won't slip like yours is. It's a nice two bolt design that is easy to adjust, but it stays put once you get it where you want it.

Agree, apply the Thomsonator. Same fate as my Ritchey. nmSpunout

As already mentioned, it's your seatpost. Consider going to a two bolt seatpost such as a Thomson Elite. I recently swapped out to a Salsa Shaft which has an independent tilt and fore/aft setting. It does what a seatpost is designed to do and it won't break the bank.
