Since you have a Mongoose, similar to mine, you could do what I did. I made an addition to my existing 25lbs capacity Transit rack. It works really well. Since your rack has the same double seat tube support setup as mine, it may work. I made it out of simple 3/4" angle iron. What's really nice is the double tube support prevents it from any possible swaying when riding.

BVH said:ElectricEd, what are using for your seat post/rack clamp pictured above where your support arms land? I need a 1 3/8", nice looking clamp for the same purpose.
I was just reading this entire thread to see if that had been suggested yet. I have the Axiom Odyssee rack rated at 55lbs cap. and want to make sure it does not rotate on the seat post as others have mentioned.gerlewis said:Hi guys, I now have this same Topeak rack problem, where it sways as I go on a journey!
My idea is to create a better bond between the clamp and the seatpost, either by gripping both surfaces with a keying of somekind, or by using something like threadlock or superglue to create a permanent bond.

gerlewis said:good idea with the ball bearing, what you thinking, 4mm - 5mm?
A grub screw glued in place might do a similar job, though im not sure where on my clamp I could drill a hole to be honest.
I need to do something, as its not up to the job as it stands, swaying this way and that.

I think it may work well to find two racks that nest well on each other and clamp them one over the other on the seatpost. If you were to do that and add struts between the two, I think the major limitation would be seatpost strength.
