Is there any way to attach a rear luggage rack to a bicycle whose dropouts do not have the proper eyelets? It needs to be pretty solid (i.e. be able to carry a kids seat)... Can it be done?

Stephan,
There are child bike seats that attach directly to the frame (both front and rear styles). Do a Google search for "child bike seat". If you already have the seat and rack, ignore this suggestion.

I am building a bike for my brother. I don't do kid seats...he may have to keep his old bike (or get a new seat), because I can't seem to be able to find any way to do it.

Black Rack Mounting Kit

Stephan,

Back in the 70s Blackburn had a simple kit for mounting their rear racks on bikes without fender eyelets.

It was composed of 4 flat stainless steel washers about 3/4" in diameter, two 5mm or 1/4" x 5/8" stainless socket head capscrews (Allen head bolts) and 2 stainless nuts to fit with "Nylock" bushings in them so they wouldn't come loose.

You placed one of the washers on each side of the dropout opening, put the bolt through the washers and through the mounting hole on the rack leg.

They may have had a rubber bushing to fit between the washers and some additional small lock washers too.

I think that they sold for a buck or two for the kit.







Also, get some plastic covered wire harness clamps to mount the rack to the seat stays if it didn't come with a sturdy mounting system.

Better yet, from Topeak.
I would not use it with a carbon fibre seat post.
I have one of these and it works really well. Very impressed.
Doesn't come loose and no vibration, and I have packed the bag as full as I can with no ill effect other than the slight change in balance of the bike that you always get with a rack. The Pack slides on and off the rack on rails with a quick release catch.

I used one of those Blackburn adapter kits back when I took my racing bike on tour and it worked great. The washers were really aluminum disks that were machined with a flange to fit into the dropout. It was a very secure attachment for campy dropouts w/no eyelets. It was a simple set of aluminum disks that fit into the triangle cut-out in the dropout forging. I still see those kits, NOS, turn up on ebay.

Correct! Embarassed

It's been ~35 years since I messed with those things but at least I got the concept correct... Confused

We only sold a few of them because most of our bikes came with fender eyelets plus most of the folks who owned "racing bikes" without eyelets wouldn't be caught dead with a rack on their bike! Wink
