On this bike without a lot of expense and modification your basically stuck with the 1 piece. But for Schwinn like this there is nothing wrong with it. If you rebuild replace the BB it will work just as good on this bike as a 3 piece and be more correct to the bike. There really isn't a good reason to change the crank on this if it is good, even If bad I would replace it with basically the same Schwinn crank which aren't very costly.

There are adapter kits, but zukahn1 is right that it's not worth it. It won't improve the bike, and it's expensive. Why do you want to replace the crank?

There's nothing crappy about Schwinn's one piece cranks. They're strong and the bearings were amongst the best when they were made.

The one piece cranks on the old Schwinns are one of the best features they have going, most are good looking, they are strong & plentiful. By the time you bought the adapter and new crankset you wouldn't gain much weight saving or performance by doing so Is there something wrong with the cranks you already have.

I agree with the others leave the Ashtabula crank in there. if you can remove, clean, lube, reinstall and adjust without cursing you are on your way to being a good mechanic.

Here is the adaptor and you need to get it installed so it will not move but also so you don't strip anything. then you have install a bottombracket for the cranks you wish to use.



I susggest though you leave this crankset in the bike then buy another bike with a 3 peice to learn in it.

Thanks for the replies. The crank rides a bit wonky. Probably a combination of pedals and crank.
That's why I'm looking at other options. But if the cranks are good then cool. I'm not really trying to spend 3piece money.

Wonky? If the crank is bent replace it. It could be that a pedal spindle is bent, which is not all that uncommon really. If it still has its old pedals that may be the case.

"Best" cheapest place to get parts for an older bike is a donor bike. There are millions of old Schwinns out there. And of course, depending on the part, parts off other brand bikes can work as well. The last Schwinn Suburban I rehabbed got wheels from a Peugeot UO8. I just picked up a Schwinn Continental for $5. Frame paint and decals were trashed, but components were in really nice shape. They will go on another Schwinn Continental I had with good paint but lousy components.

"Best" most convenient source is ebay (cost will be more, usually, a lot more.

I keep a couple of old Schwinns around just for this purpose, along with other various donor bikes. On a lot of them, I just strip the frame of parts I can use, and then donate off the frame and other misc parts to a local co op.
