Kind of a dumb question about rear racks...

Not exactly a dumb question, but I didn't find what I was looking for with the search function.

What I'm looking for is suggestions for a rear rack that mounts on the brake bolt. I don't have rack eyelets and would be using P-clamps as well. Most of the ones I see online have struts with mounts for eyelets only, though I do see some pictures of bikes with the rack mounted on the brake bolt.

Also, I am aware of the clamps you can add to a seat post in order to mount a rack made for rack eyelets. However, this will be on a larger frame (60c) and that would put the rack pretty high up there, meaning I would need extra long legs, which I forsee as just adding another weak link to the setup. (Waiting for 5 people to post a link to said clamp without having read this part of the post...)

Axiom makes two racks that will work, the Streaminer Pro Tour and the Streamliner Road DLX, both of them have an extender that bolts behind the brake mount for a road caliper style brake.

P clamps! Maybe too fred for you but I carry a case of beer + commuter panniers full of sundries on a cheap al rack with no problems. The single strut to the brake bridge doesn't look good for lateral forces on a loaded top. I do envy the set back on the bottom of the axiom examples.

Even some cheap ones allow brake mounting. A $15 no-name thing I got at the LBS has three sets of holes in the front. The middle set is for brake mounting.

I'll echo Mauriceloridans' comment about stability. With even modest loads in the panniers, the rack becomes subject to sway. It's fine for lightweight stuff, and occasional heavier loads. You're better off with P-clips on the chainstays (not the seatpost).

As long as the rack has a place to attach a center brace, I just bend one of the struts to go forward, dive under the brake then up to be bolted in place. As long as the rack legs are secure, it is a 3 point mount which is fine unless you plan to really load it up.

Since you mention brake "bolt" I assume you have a rear caliper brake. If that is the case, then there are options as mentioned above. If you have cantilever brakes (i.e. "bolts"), then Old Man Mountain makes racks designed to attach to those mounts.

http://www.oldmanmountain.com/Pages/...RearRacks.html

I have a few of their racks and they have stood the test of time. I have one mounted on a Langster fixed gear to the seat stays with rubber coated p-clamps they supply. I have had it on there for years and it has been bombproof.

There are several options. Delta offers a center stay for their Mega Racks here (look at the hardware near the bottom of the page). You can use p-clips...but I agree they are sorta ugly.

The Tubus Fly uses a center mount but it's not cheap...a great rack but not cheap.

Tubus also sells a better clamp than the p-clamps. It's easier to use and looks better.

Many racks could easily be modified to work off the brake bolt. Topeak Explorer you could drill two holes in the center of the plate the double struts mount and you would be good to go.
Now a word of warning. A single mount is going to allow the rack to twist around more then doubles would. I would keep the load light or reconsider the P clips.

...I already said I would be using p-clamps or something similar. I have a seatpost mounted rack right now, but as was mentioned, it can sway quite a bit with some pounds in the panniers. This is why I was looking at other options.

The Tubus fly looks really good, I might have to save up for that one. The axiom rack linked above looks like a great concept, but I read a few online reviews that point to some design flaws. Namely that all the important mounting points are thinish flat stock.

Any other recommendations?

I have an inexpensive Bontrager Back Rack II that comes with hardware to mount to the rear brake. IIRC, it was under 20 dollars and it has served me well.
