Fascinating reading. Thanks guys. Interested cos I have what I believe is a b3 with oval downtube with a pair of f3 forks. Unfortunately the rear shock is a tad lacking, what options are there for rebuilding or replacing?

Hi ZTH,
I've not seen a specific parts list for the shock, but the AMP shock is a pretty basic coil over oil shock.
Details in the middle of the AMP 1997 service manual, here: https://www.dropbox.com/s/cm4utlrpjveys ... l.pdf?dl=0
Best option really is a new Risse Genesis air shock
$198 + shipping.
Specific shocks for the two B3 specs, B4s and the B5 still available.
Here's the two B3 versions. The difference is in the diameter of the shaft clamping shaft (wheel end, left):

Kevin Risse ([email protected]) still services old ones if you find one (and a whole load of other old shocks etc). https://www.risseracing.com/airshocks.shtml
Although AMP themselves don't offer product service anymore (They did stop making them 17 years ago, now :shock: ), there are some useful manual/brochure/info downloads here: http://www.amp-research.com/company/his ... ain-bikes/
All the best,

I'm looking at an AMP Research which has carbon rear stays and a carbon F4 front fork.
Is the F4 much of an improvement over the F3? I know there is more travel and weight, but it doses look somewhat beefier. I'm looking for an XC bike.
There are some comments online re failure of the rear carbon stays...anyone any experience.
Sizing is the most difficult aspect of this and thanks to Dan for his very helpful explanation. The frame is medium, but I'm not sure about the seat post. Are they relatively easy to find if an alternative size is required?
