I bought a second hand Spesh, but under the chainstay protector is a large crack. Where can I get a replacement aluminium chainstay? Thanks. Its a 2015 Specialized Enduro Comp

From Specialized via one of their dealers? Good luck. Andy

...with a whole new frame attached. Or, maybe ship your frame back to the factory in China to get a new stay welded in.

It's an Antique now. Best bet look for a used one. Or get your money back?

I had thought this bike had rear suspension, thus a bolt on potential stay replacement.

Just the same if the frame is not repairable then perhaps approach the Specialized dealer about a crash replacement deal. Of course the second hand status likely makes this option moot. Andy

AnkleWork

Good thought -- apparently is does have full suspension so maybe a bolt on swing arm is available.

Update, I have just found a donor frame which is a different size to mine (shouldn't matter) but the seller states that there is a bad rub mark on the chainstay. Does it look large enough to affect its strength? The seller states that "the rub mark just breaks the metal surface, don't think it would effect strength but would always reccomend having a welder run a small bead of ali over the top to be safe"

The problem I have is that I live in a country where there are no specialized dealers, not even a single decent bike shop either!!

I'm a bit worried about the front triangle of my frame now, considering how badly cracked the rear triangle was. The seller claimed that it was squeezed in a tight spot during transport. How can I properly check the front triangle for cracks?

HillRider

I think you are throwing good money after bad. If the chainstay is cracked and the rest of the frame questionable, I recommend getting an entirely different bike.

The rest of the frame (front triangle) looks alright, just a few paint chips here and there which is normal. It has been invisiframed in some areas. I have gone over most of it with a flashlight looking for hairline cracks. I'll try and take it to a metalworking/car factory to get it looked at.Quote

That "rub mark" on the possible second frame looks to be into the tube wall. Knowing it's compromised why buy it. The first frame should have taught you that, had you known of it's crack you likely wouldn't have bought it to begin with.

It's uncommon for a frame to have cracks in more then one location, but not impossible. Without metallurgical scanning devices the most lay people can usually do is a VERY THOROUGH look over. Andy

I haven't worked at a Spec dealer, but most manufacturers keep rear triangle parts for FS bikes around for a few years. Seriously, have you contacted a dealer? Specialized dealers aren't exactly few and far between. Rear end parts seem to break more often than main triangles. If the front looks OK, I wouldn't worry about it too much.

If it's been ridden enough to crack a chainstay look forward to likely necessary pivot and suspension service. These are very frequently neglected by most MTB riders.

The chainstay was cracked because of neglect while transporting it. I've checked the front triangle and there aren't any clear cracks. I've dissassembled the pivots and the bearings feel smooth and well lubricated. I have contacted Specialized themselves to try to sort something out.
