Which is your choice...???

I think the air shock's damping rate is row

so coil shock is a little advantage

just I think... haha

We used the coil shock until now
The air shock try to next year
When the air shock using, what is a bad point.

I've heard they have horrendous stiction. No expierience with them myself.

I would run some tests to see what the changes to damping characteristics are due to temperature change.

Tony Foale's book, Motorcycle Handling and Chassis Design, talks about this subject in Section 6- Suspension Principals.

You can get some objective information there. To sum some of it up, its the spring rate of air shocks that can sometimes suck, not necessarily the damping.

The one thing I would worry about is blowing a air seal on an air damper. granted most mountain bike air dampers can handle alot of punishment from a 250lb rider, Three foot drops or more, but it would still be a major concern. But on the otherhand the weight savings could be measured in pennys but pennys means speed. I think intensive testing should be done before you fully settle on this.

Back in '98 and '99 we ran the Cane Creek air spring/dampers. Very high stiction (at least 1/2" in ride height variation!), plus no "negative spring", and not very easy spring rate (vs. spring preload) adjustment.

mountainbike air shocks have come a long way since then! even guys who race downhill now use air shocks, they've come along that well. though i don't know how suitable they are for fsae.

Through further investigation I did find that some shock manufactures are making air shocks for SuperCross bikes now. So on a rebutle of my last post I guess that they are getting way better then my initial thought. I would recommend just looking into it more thoroughly.
