Tubus Rack Question

I just installed a Tubus Cosmo rack on my bike and it seems pretty straight forward except what holds the rack level? The two rods that attach to the seat stays don't seem to have a firm attachment on the rack. They hold tight in the inboard and outboard direction but forward and back is unclear. Can anyone give me some help?

On my tubus cargo rack there's a nut and bolt underneath the rack that holds the fore aft position.
I thought all rear tubus racks have the same mounting hardware.

Yeah, there's a nut or screw on the little posts underneath the rack that needs to be tightened - possibly on the side of the little post.

There is a nut that tightens onto the rod, which is meant to stop the rack from moving fore-aft. HOWEVER... it's possible that your rack came with that hardware mounted backwards, which means the nut cannot clamp the rod no matter how tight you make it. This is what happened to me with my Cosmo - I thought I had everything tight, but then on my first test ride the whole thing suddenly swiveled backwards... very embarrassing. Took me a couple of minutes of scratching my head before I realized why the nut wasn't stopping the rods from moving. I have no idea why they would ship them like that, but they did. So just look at the clamps that the rods go through, and if tightening the nut does nothing then try reversing the side which the rod goes through (i.e. flip the clamp 180 degrees so that the other side is facing outward) - then the nut should engage the rod and clamp it when tightened.

Thanks Neil, I think that may be the problem because I have tightened the nut as far as I'm comfortable tightening it. I know this isn't rocket science so I'll try your suggestion.

Again Thanks

I just fixed the problem and you were right Neil, The tombstone shaped parts that hold the rod holders were assembled backwards so they could never be tightened enough and the side with the shallow bottomed hole had the nut in it so I turned those parts so the rod holder fit into the recess which allowed the rods to be held against the side of the tombstone looking parts. Now they are working properly. I would have thought that Tubus was a little more together than that...oh well...mission accomplished.

Thanks for the help
