Kurt, thank you for offering this up. I want to attempt a repair before I look to make a change. The bosses that I have at the moment are painted to match, and Iíd like to keep the bike as original as possible. If I crash and burn, I will send you a PM to see what we can work out.

Thanks!

Glad to offer it. Like you, I hope you won't need it - the original, painted boss is a beautiful touch on a beautiful bike (and that color is scrumptious).

As others have said, take a look on McMaster Carr to see if a small enough pop rivet can be had. Aluminum pop rivet, not steel - you don't want imminent corrosion. I also wholeheartedly back the suggestions of epoxy (though I'd like to know the chemical reasoning why some recommend against JB Weld).

Clean the area well. Better than you've ever cleaned anything.
Get a GOOD two part epoxy that is applicable to aluminum (I would think a marine application would be a good place to start looking). Prep the surface the way the epoxy manufacturer specifies.Epoxy technology has come a long, long way since the bike was originally assembled.
Do not use JB Weld!
Get good, correct sized aluminum pop rivets, and install them in the existing holes as the epoxy is setting up.
Between a GOOD epoxy and the rivets, you should not ever have an issue with them coming off again.

The company I work for orders from McMaster car often, so I planned on starting there. I also suspect our maintenance dept has the istallation tool. I donít want to purchase a tool that I may not use in the future. I will look for better 2 part epoxy as well. I want to do this only one time.

By the way, I see you're from Canton OH. So am I! Now in KC.

Cool! I donít see many vintage bicycle enthusiasts in Canton, so I bet we crossed paths at one point or another. Does your user name indicate that you are a pastor?

Maybe so. Yes, I pastored in Athens, OH; Uhrichsville, OH and Warren, OH among other cities/states. Now Iím at Nazarene Theological Seminary in Kansas City. I grew up in Canton; I have family there that cycle and collect bikes too.

If you really want to do it super right, use 3M 2216 B/A gray epoxy and acid etch first.

I maintain that JB Weld however is good enough for this application. Either adhesive will far exceed strength requirements if applied correctly. Note that by JB Weld I mean the long cure stuff, 60 minutes or whatever. The 5 min version is useless.

Ha, I went through Warren, Ohio several times, in the late '70s, to get to Nelson's Ledges State Park. I'm not admitting to skipping school, lol, but that was a common practice back then. 😁😉
BTW, school was in Niles, Ohio, birthplace of former President McKinley.

Oh, yes, Niles. Iím very familiar. Iím also familiar with Nelson Ledges, haha. My kids probably skipped there too

There is a very nice Western Reserve Greenway rails to trails that goes through Niles, Warren and north to Lake Erie. Plenty of great trails, paved and crushed limestone within reach there.

Ohio is always on topic for me, so feel free. When I first started cycling in Canton we did not have many trail options (that I knew of). Fortunately, they have built and expanded a whole lot of trails over the past 10-15 years. I live just a few feet away from the new East to West route that connects the two major north/south routes. It also will tie into the national bike highway! I donít know if you are familiar with Malone College, but I live within sight of it.

i missed the part about the bike. Itís an 83 ST-500 (AA serial number) Itís the first year that Cannondale offered a bike. Itís an eclectic mix of nice parts. Superbe shift levers, superbe tech RD, Cyclone FD, gran compe brakes, SR Apex triple crank, Suntour sealed bottom bracket and Suntour sealed hubs. The bike is surprisingly light when I pick it up.

Yes, Iím familiar with Malone. The last place I lived in Canton was with my parents off of Market North of Applegrove. My brother regularly rides the trails there in Canton and vicinity. Iíd like to come back and check them out. I did do the TOSRV (Tour of Scioto River Valley) with my sons and him last year.

Itís cool you got an AA in Ď83! I bought a Ď85 Cannondale brand new for $450 when I was in college in Marion, Indiana. SR-300 model with Suntour Cyclone etc. and loved it. They looked different from anything on the road at the time and felt light and fast.

I guess you are going to have the "rocks in the hubcap" syndrome, or did you get them out?

No, still in there. I planned on pulling the bottom bracket at some point.

Update:
I was adding up costs for this project. I figured I was looking at 50 dollars at a minimum by the time I purchased stainless rivets, epoxy, acid etch, rivet tools, etc. I decided to call an LBS that I trust and ask them. It turns out they have done similar repairs. They are going to prep and use a 3m epoxy followed by rivets to hold while it cures.

I love that bike shop. They have all the odd parts along with knowledge and appreciation for old bikes.

I asked them to check the derailleur tab alignment while they have it too.

This story has a happy ending. I picked my bike up yesterday and Ernieís bike shop did a great job on the repair. They used 3M epoxy and rivets. I feel confident that the shift lever wonít be a problem anymore.

Today I rode it to work for the first time. I could feel the difference immediately, but after about 5 minutes the bike just felt normal. I have been sick for about a week. Iím looking forward to riding this one with healthy and fresh legs.

Very nice. I have a 1989 ST600 that is a great bike. I switched to 700c rims and Compass Bon Jon Pass 35mm tires. New BB and new headset, the rest serviced, assembled, and tuned. I also switched to Tektro 539 dual pivot nutted calipers and the braking is very good. This one is a keeper.
