Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

Old Schwinn. Need help ID'ing and finding part sizes

Hello,

I recently acquired this old schwinn and I'm looking to figure out what model it is and what part sizes I can get for it. I want to convert it to a single speed, but I don't know the exact process (I'm reading the sheldon guide, atm).

Here is a pic of the bike (or what's left of it): http://imgur.com/La99z.jpg

I believe the headset is intact, but it's clearly missing a stem and handlebars. Any suggestions on what would fit? Also, I'm assuming it used to run on 700c wheels. As far as the cogs/crankset/chain etc, does anyone have any advice?

I apologize for being a total novice but I'm a fast learner, I swear.

Thanks!

Alright, I understand where you're coming from. It's definitely cheaper to buy a stock singlespeed/fixie like a Kilo TT or Cutter than fixing up an old frame. Assuming the only thing I wanted out of this experience was a working bicycle, you would be right. But, in my mind, I'm using this experience to learn more about bicycles so that I can perform maintenance in the future and help friends fix up bicycles too. For that, I'm willing to invest time and money for the long term knowledge pay off.

So back to my original question, in my persuit of finding parts that are compatible, there seems to be a lot of variations in sizing for things such as stems, cranks etc. If anyone knows any resources or measurements that would work on this bicycle, again, I would appreciate it greatly.

Thanks!

Actually looks like a pretty good Schwinn, can't ID the model from that shot tho. Crank should be fine, just toss on some wheels, bars, stem, brake, chain and you'll be ready to roll.

Don't listen to earthe5ive, lugged Schwinns are pretty much indestructable.

Also don't listen to earthe5ive about those prices. Wow, where did you get that stuff?

You can get a set of perfectly fine puncture resistant tires from the LBS for $17 a piece. You don't need to go straight to the gatorskins. You can get tubes 3 for $12.

He's also giving you numbers for things like cranksets (which you already have), freewheel (which comes included in your $180 wheelset), and repacking the BB/headset ($70? more like $7 for a tube of grease).

I'm not saying this thing will be cheap, but you're looking at probably $300-$350 to get it road-worthy.

Can you find out what model it is? It's usually written across the top tube, it looks like there is still some lettering there but we can't make it out from the picture. If it's a Varsity... meh, maybe not worth it. If it's a Sports Tourer or Super Sport or Superior, then is definitely worth riding.


ONE PITFALL I'd mention is that you are NOT going to be able to find replacement chainrings for that crankset. The inner is 118 BCD and the outer is I-don't-even-know. Before you ride it, definitely take time to replace the bolts on the chainring. I learned this the hard way.

I would agree with this estimate, and you'll develop a deep bond with the bike while doing the build that you wouldn't get by buying some cheapo new bike.

I would also mention that earthe5ive is employing a major double standard. That Schwinn Cutter isn't coming with a $180-$300 wheelset, nor $70 combined bottom bracket and headset. If you could buy all the parts on that Cutter yourself it would end up costing you more than Performance is selling it for, but if you're building up your own bike, you wouldn't choose those parts.

This is probably more accurate.

This will probably take a 1" standard stem. Most likely all the parts will take standard sizing, except the double cranks as stated earlier will not take new chainrings.

Also keep in mind that the $350 or so includes buying a few tools you probably don't already have, like a crank tool, chain tool, etc. These are good things to have, and you'll be happy they're around for the future when you start doing all your own mechanic work (using the skills and knowledge you gather thanks to your conversion experience).

Lockring tools and chainwhips are nice to have as well, but there are DIY solutions to those problems.

Thank you for all of the advice guys. I'm definitely sticking with this project.

How are these items (for fit not necessarily for quality):

Stem: http://cgi.ebay.com/ORIGIN-8-TRACK-F...3%3A1|294%3A50

Handlebars: http://cgi.ebay.com/EIGHTHINCH-BULLH...3%3A1|294%3A50

Wheelset: http://cgi.ebay.com/NEW-RED-VUELTA-T...3%3A1|294%3A50

I have the original front brake calipers, need to replace the pads/cables though. I have the original seatpost and a seat from a different bike that would fit nicely on it.

Any advice how to pick out the chain? It would be the last thing I need.

I live in DC too and City Bikes sell tubes for $12 a piece. Which place did you have in mind?

All that stuff looks like it would fit just fine, you could probably find better quality parts for cheaper, but for a first project it's fine. I have a similar wheelset and haven't had any problems with it.

Here is a cheaper stem: They have it in different lengths, too. It's the one i've got on my road bike. Its holding up just fine.
