I used to break stuff pretty regularly, but I think since running air suspension I haven't really broken anything much? Lots of tokens, pretty low sag, it just never seems to hit bottom hard anymore.
You're onto something ^^ that's worth repeating. I suspect OP is breaking frames due to hard bottoming or the super-long seat post like already mentioned. Run something with lots of ramp or bottom-out control. MegNeg with tokens, Cascade Link, progressive spring or whatever other method you can find to keep from bottoming too often or too hard. Frames with a good amount of progression are key, but MegNeg will make a lot of frames ramp up nicely.
I'm only 6'2" and around 200 lb riding weight and I've broken a lot of frames. Partly because once I have a bike I like, I keep it until there's a really compelling reason to upgrade. I've broken frames at a slower rate now that I'm dialed in to setting up my suspension so it doesn't bottom. I wish I understood this better in 2005, holy crap I killed a lot of frames around that time.
I'm also done with aluminum unless it's a tank due to welds failing at about the 3 year mark. Not that carbon can't break... done a few of those too, but usually a manufacturing defect instead of being weak.
