advice needed - overactive rear-end!

crimsondynamo

I have a new full-suspension bike and I'm tying to get used to the handling. The one extremely disconcerting aspect of its behaviour occurs when going over a couple of table-tops where I ride. I'm not trying to catch big-air, I'm just trying to roll at speed. The back end flips up such that I rotate headfirst-wise in the air.

I suspect the shock gets heavily loaded in the preceeding half-pipe, then sort of springs the back wheel up when everything goes "light" at the lip of the table-top. Could this be right? I've got my rebound front and rear set half way.

Any advice greatly appreciated.

more rebound definately if you are feeling it noticably kick, depends what shock you are running for this. (shameless plug) the Fundamentals DVD I am selling on e-bay at the moment has an excellent suspension set up part done by Tim Flooks from TF Tuned which is very detailed. (shameless plug over)

What bike, what shock?

What bike, what shock?

Stumpjumper FSR Elite 08, which has a Fox Triad shock (psi'd to my weight)

As above, sounds like thre rebound needs tweaking.

Just to be clear, do I need more rebound?

That seems counter intuitive, but I'll give it a shot.

Whatever works best! Have an experiment.

But, looking at what you said, I'd say a little more to stop the back end kicking up so quickly.

you need to slow the rebound down a bit, so that it doesn't buck you off, less rebound would do this, but experement with just a couple of clicks at a time.

And keep your weight back too. Anytime you get airborne the bike will start to nosedive - how quickly it does this is largely a question of how fast you are travelling, and how much weight you have over the front end!

Learn to shift your weight on the bike to help minimise this.
