Bicycle Mechanics - Rear rack with no braze-ons (sp?)

Hi. Trying to figure out how to attach a rear rack to my bike. I have eyelets down near the rear sprocket that I can attach the bottom brackets to but I have no holes (I think they are called brazeons) or fittings to attached the top of the rack to the bike. I have looked at the racks that attached to the seat post but they look like they would sway and move around. I want to start commuting and need to carry a change of clothes and a laptop computer and a planner. Probably 15-18 pounds or so.

Any thoughts or fixes? Is a backpack just as good?

Thanks
Adam

There are racks available that attach to the brake bolt of caliper brakes.

You can also attach a rack to the seat stays using vinyl coated clamps. Go to http://www.thethirdhand.com/index.cgi and search on "clamp."

Old Man Mountain Racks (http://www.oldmanmountain.com/)

Some rear racks include 'P' clamps which clamp near the top of your seat stays for those frames without braze ons. They're sold separately as well.

Old Man Mountain racks are very nice but pricey...

Some additional info on Old Man Mountain. They use a tandem skewer (sp?) to hold their racks on full suspension ATB's. They also will work with you for solving mounting problems. They helped me work around disc brakes to mount my rack. You might call them.

Any rack can be setup with 3-point fittings. I have used a cheap Blackburn clone , you just need a bit of metal which bolts to the two slots at the front, and you bend/fold it down to the brake bridge. You bolt the fitting using the caliper brake bolt (if you have calipers), or an M5 allen bolt. The metal fitting is a kind of triangle shape with a hole in each corner.
You can also use P clips, or get a local frame repair shop to braze on some fittings.
You dont need an expensive rack for everyday use, but the Blackburn design is a good, light, simple one.

Why not simply get a Blackburn MTN Rack and replace your seat binder bolt with either a quick release or a regular bolt-and-nut? This makes a more secure mounting than the over-the-brake thing.
