I read a thread by Bigboy here where they were warning a bike builder
about using shocks in this manner and the bottom line it was liable
to fail.

Are you using the shock on a fork?

Huh? I asked you a straight question, "Are you using the shock on a fork"?

Punctuation and capitalization would help........

Shocks can fail in extension but I guess a failure on a soft tail
is better than on a front fork?

motorbicycle racing okayy sorry about that i thought by my answer it would be obvious its not in a fork.

wheel bender can you put a link to this bike you are on about up if possible i would like to see a picture of its location and use. never realised they were different styles of shock, should of been obvious to me since i studied hydraulic and pneumatic systems in college though.

Hers is a link to a page in Scotland about the pull shock.

Some of the more complex compression bicycle shocks are the
Specialized Brain shock and the Pro Pedal (produced by Manitou, I think). These shocks
will become rigid while pedaling hard to transfer more of your energy to the rear wheel but still
allow rapid compressions as you hit the bumps.

just to close this thread nicly i discovered that a air shock can be used in either direction but to do so in a dirction it is not intended for automatically voids warranty on parts. i read on mtbr forum a poster said that he had done this. he simply put more air in side where the rod of the cylinder is than on air chamber and les in chamber. of cousre this changes where rbound and all associated parts of shock travel in relation to ordinary usaeg but i repeat do not buy a new shock and do this if you want the warranty to last as if they discover for a conventional shock was usd as a pull shock it is automatically voided as misuse. :-||

Cool. You just add more air to the rebound side than the compression side of the shock. If you could buy a used air shock, you wouldn't need to worry about violating the warranty.

If I recall correctly almost all the Buell motorcycles used a shock that woked in extension rather than compression. Not an Air shock though
