Looks like I just joined the AltRider Luggage Rack Stress Fracture Club!

Think I’ll steer clear of Alt Rider stuff. That’s a catastrophe waiting to happen!

Too thin to use those tapered head bolts. A cap head bolt with a wide washer would prevent this, but the top would no longer be perfectly flat.
I run the nordic rack. Its 3/8” powder coated steel. Heavy but you can stand on it with no issues.

How long have you had that rack and how many miles of use?Looks like I just joined the AltRider Luggage Rack Stress Fracture Club!

Any chance a heavily loaded top case may have been a contributing factor?

Nordoc? Never heard of it? Do you have a link?
Just over 2 years and 10k miles, 90% of which was on slab, the rest fire roads/easy trails. No stump jumping.
Not likely. The topcase is usually empty aside from raingloves and a small bag. Less than 2-3 pounds, tops.

Sorry, Nordic
Looks like they dont make it anymore.
Heres the best pic i have of it:

Omg thank you.I think you are looking for Nomadic racks.
I bought it forever ago and it only has an “N///“ on it, so i was not recalling the name correctly.

I wonder what alloy altrider is using?

I took my AltRider rack apart yesterday to check for cracks and to get some measurements for some modifications. From the pictures of failed racks, it looks like all the cracking starts at the sharp edge at the bottom of the countersunk holes. As long as I had mine apart, I ran a 27/64" drill through all the countersunk holes to remove the sharp edge. I then deburred the holes. Everything went back together just fine with the same hardware. Remember to put the longer spacers toward the front of the bike. The other modifications might have to wait until winter. FWIW, I did not have any cracks in my rack, but I don't have a top box and very seldom put a large load on it. The 27/64" drill (.422") is about .060" larger than the original holes. I think I measured the original holes at .360". Keep in mind that the countersink angle on metric fasteners is 90 degrees. SAE fasteners use a 82 degree angle. The aerospace industry uses a 100 degree angle for thin materials.
My thoughts are: if a top rack, which doesn't regularly receive impacts, cracks/fails like this. . . . what should be expected from the skid plate(s)? I understood when I got mine, that it was not a hard core plate. But, I'm betting that bouncing off of a curb puts a lot more stress on it, than the top plate receives from anything that people put on it. Unless a person is in the habit of carrying gold. . . . or lead.

Their mounts appear to be made of soda glass they fracture so readily.
Seriously, do they have a metallurgist on staff or at least someone they consult with? Alt Rider charges too much for any product they make and to have ridiculous failures like this due to design or material issues - thanks, no. I'd rather spend less money for better products elsewhere.

I've had my Givi plate for 5 years and the top case always has between 15 - 60 pounds worth of "stuff" inside, including 2 bowling balls when I would sub on a league! No cracks, everything is fine.

Wondering if they chose a cheap brittle alloy to save on raw materials costs. Even a proper alloy mic can become hydrogen embrittled if not processed correctly and cleanly.

The Nomadic rack isn't steel it's aluminum too, but it is 1/16" thicker than the AltRider one. Did they used to make a steel one?

No i am clearly just an idiot who has forgotten the details.
Stuck a magnet to it, its non ferrous so certainly aluminum.

It's ok
What kind of topcase do you use with it? They claim it is Givi Monokey compatible but it doesn't look like it has the holes needed for mounting the rear pegs.

Givi Monokey will work on it. I've got a V46 on mine.
I've checked mine and recon it is mounted in a different way. The plate ain't bolted to the spacers directly but rather there is a bottom U shaped plate below it.
I'm touching iron but it seems this application shall resist (hopefully) better.
Pics hereafter to explain what i mean
