Seatpost Rack Mod
I would like to install a rear rack on a mtb frame that has no eyelets. I'm thinking about modifying one of those seatpost supported pannier racks by somehow attaching the bottom of the pannier supports to the seatstays by a way of aluminum brackets. Has anyone done this? Thanks...

Am I reading you right? I am a bit confused by what you mean by seatpost rack, are you talking about those racks that just clamp to a seat post with no bottom support and a low weight limit?
If you're talking about modifying a seatpost rack to keep the rack from swinging around, do you have V-brake bosses on the seat stays? If so, you can get a 90degree angle bracket and perhaps a longer hex bolt and put the 90deg bracket behind the v-brake cantilever and then use the longer hex bolt through all. You might not even need the longer hex bolt! Now, once you have the angle bracket on, all you need to do is rig up some support from that to your seatpost rack and you're set. The only disadvantage with this, is, depending on the angle bracket you use, it might hinder the parallel arms on the v-brake so you might not be able to open the pads as far as normal which might interfere with removing a full MTB knobby tire when not flat.
I have a OMM rack on a bike with lower eyelets but no upper eyelets so I use this method for the upper support on my rack.
Hope this helps!

Fixer,
I remember seeing this last year. It belongs a former poster named Anton Kroupennikov. I don't have any useful information about the rack, and I couldn't get Anton to talk at the time. Still, it lends validity to the seatpost rack concept. Dig the heavy duty clamp!

Thanks, Buddha.......that's exactly the setup I had in mind. Looks like the rack bottoms are either axle or frame supported........ definitely not canti boss supported.
On second thought, from looking at the photo, canti boss supports alone may not be such a good idea to support the weight of the load from the bottom.

No problem , Fixer
It looks like some kind of two-armed strut is supporting the rack from the seatstay. I think supporting from the canti-bosses would work better on a much shorter rack.
Best of luck,
BK

Those are probably racks by Old Man Mountain. They specialized in racks for bikes without eyelets.
You can mount a standard rack with some clamps like these (scroll down to the Stainless Steel Coated Clamp).

Old Man racks ride on their special quick release axle mounts and are stabilized by arms bolted onto canti bosses. Since I already have one of these seatpost clamp pannier racks made by Delta, I was looking for ways to support it from the bottom. These seem like solid, bulletproof racks.

Riderx, up in the space!
This is off subject, but is there going to be a 2004 SS Rally in Philly?

I decided to save my seatpost clamp pannier rack for a future commuter project. Meanwhile, despite the slight hassle with wheel removal, I ordered and received an Old Man Mountain Sherpa rack for my mountain bike which has no eyelets. It is a rock solid minimalist looking mount.
