What should I do with my Schwinn?

Last year I decided I had enough time away from my two young girls that I could start cycling again.
i contacted an old friend of mine to ask him to refurb my old Schwinn so that I could start riding again.

Unfortunately he found the headtube cracked when he was in the process of stripping and cleaning it.
As a replacement for the time being, we got a Surly Pacer frameset and swapped as many of the components over as we could.
So now I have a functional bike again, I just don't know what to do with this old Schwinn frameset.

any suggestions?

This also brings up another question I have had recently.
Is 4130 the new Hi-Ten?
heres what I mean:
With the advent of newer tubesets such as 853 has 4130 been relegated to the "Gaspipe" status?
This of course comes from my Surly Pacer frameset. Did I downgrade from the Schwinn frameset to the Surly one?

Any thoughts?

i have attached a few pics of the Schwinn if anyone has any suggestions.

I thought 4130 is cro-mo?

take the fork out and look inside the tube, is this crack due to metal fatigue or shoddy brass work?

I think a frame builder could open and re-braze that if the steering tube is infact intact.

Well, I agree that it is, I am just wondering if I downgraded from the frame I had.
Also it seems that with newer and more advanced tubesets like 853 or SLX etc if the lower rung of steel frame bikes that have been relegated to 4130 could be considered low quality since the tubesets are not as advanced as some others.

The pacer frameset is full 4130 TIG welded with double butted main triangle.

Is the fork straight? Did you hit something or was the bike possibly hit in the garage? While tenax is not top of the line it mightbe worth having it evaluated for repair.

4130 is a lower grade of ChroMoly tubing, Hi-Ten is hight tensil steel, while I am not a smitty nor trained in the arts of metalurgy I believe both have completely different moleculear makeups.

The Surly uses a 4130 labeled frame? they didn't even bother to put some kind of custom decal on it?



Is this where the seatpost was when you riding this? If so it was too big and your better off staying with the Surly or buying a smaller frame.

IMHO yes you down graded. However you likely to spend 50% or more for a frame equal to the Tenax schwinn than you did the Surly.

The Pacer frame info is right off of the website for that frame.
I have attached a pic of the tubing sticker from the Pacer frameset as well.

The actual tube on the schwinn is cracked. If I rotate the frame so i am looking at it from the non-drive side I can see where the crack extends away from the lug itself. I do have a local shop (Assenmachers) capable fo doing the repair, I am just not sure whether it is worth it or not when i consider the repaint costs along with the repair costs.

The schwinn was never in a wreck. it was hanging upside down in the garage when I wasn't riding it.
I also have a distinct memory of a 35mph descent that got harry due to instability in the front end.
Looking back on it now, I realize that the tube was probably cracked at that time, and I just didn't realize it.
I put a lot of miles on that bike and i have very fond memories of riding it.
Its had a relatively long life and while I don't know whether I could part with it, I am also not sure I could afford to fix it.

Should I pass it on (maybe sell it as a damaged frameset)?
Should I cut it up and turn it into a shop stool?
Should I just hang it on the garage wall and let it remind me of the past?

I'm sure a framebuilder could fix it, but the question is if it would be worth the expense to you?

If you decide not to fix it, making a shop stool out of it would be a pretty cool usage of a frame that has personal significance to you.

Bianchigirl,

No, the seatpost was not at that location when I was riding it.
I am 6'4" with a 36" inseam. i think I was about at the size limits of that frame.
I had enough strength when I was riding consistently that i could make that frame shift by itself on a hard climb or on a hard sprint.
i also recall a noticeable amount of BB flex in that frame.

I fear that for a rider of my size with the type of riding that I enjoy, in order to get a frame of the quality of that schwinn today that i would almost be relegated to a custom frameset.

This thread also makes me happy that my wife started riding my fathers old Schwinn circuit.
Just had assenmachers go through that one and it seems to be in good condition now.

Looks like you had a poorly brazed frame, the extra BB flex you mentioned sounds just like an '88 Premis (also Tenax) that i had a few years ago. The "dirt' ring showing on the BB/ seat tube joint on mine (yours looks similar) was actually a small gap due due poor assembly of the frame, I was able to clean and re braze the joint on mine (silver), never any flex issues after that. I'm sure your headtube problem is from a similar issue, it should be worth repairing (have the BB joints checked as well), the heat required is much lower than welding , paint damage will be fairly localized, maybe just a relatively small area to blend in.

Nothing wrong with a Surly, but they ride like tanks and lack that certain something.

If the fit of the Schwinn is perfect for you, and a repair wouldn't be too much, I'd go for it. The paint is way cool, and those frames are pretty versatile, so sentimental attachment says fix it!

Henry James still sells standard 4130 tubing. The higher strength tubing uses heat treatment to obtain higherr tensile strengths (allows thinner walls), but it is still a Cr-Moly type tubing. So 4130 is still better off than 1020. Also, what is the wall thickness of the Surly vs the cracked frame set. I would suspect, the Surly may be as thick or thicker due to Tig welding vs brazed lugs on your earlier Schwinn
