Bike from the Dead

I live for the CABE
I've been getting a little burnt out working on my current RRBBO20 entry as of late, as I've run into a few hurdles that I need to take my time with before I proceed with final assembly. I really wanted to have it rideable in time for this weekend, but it's just not going to happen at this rate. Plus, as much as I want to build my factory green Schwinn straight bar cruiser, what I really want to build right now is another klunker.

Specifically, I want to build a single-speed, low-gear klunker to test a theory I've got about why I see so many single-speed klunkers with such small chainrings, as opposed to klunkers with multiple gears. I'm sure everybody who's already done this knows why and has explained why, but I learn better from hands-on experience. My guess as to why so many folks build klunkers with a single low gear as opposed to having more gears, aside from ease of assembly and maintenance, is because you don't need a higher gear for going downhill, as gravity is on your side there, but you need a low gear for going uphill. It never really clicked with me until I rebuilt my step-thru klunker to have 7 gears, and spent more time riding in a lower gear than a higher gear. I also got a better sense for that when I rode a Mongoose Dirt Jumper alongside my 7-speed klunker this past Monday.

I want to find out whether riding a single-speed klunker with a low gear and a coaster brake is just as good, if not better, than riding a klunker or mountain bike with multiple gears, shifters, derailleurs, caliper/v-brakes, and all that other stuff. I certainly know which one I'd rather build, but I want to find out which one's more fun to ride. Up till now, my only problem with that was that I wanted to paint the bike I planned to build to test that theory. That all changed when I got an idea yesterday for a frame I bought at Haysville, Kansas this year for $4.
299028-BftD-haysville-haul-2025-29.jpg


I'm not 100% sure what it is, but my best guess is that it's a mid/late-'30s CWC. I bought it because I thought it was Colson, but the tank area's narrower than a Colson's. The fork that came with it was junk, the rear fender and rack are probably not original to the frame, and the chain tensioners have been replaced with flathead bolts, but the frame was nice and straight, and the price was right.

Headbadge reads "NONPAREIL BICYCLE WORKS Speed ST. LOUIS, U.S.A. (Part of the reason for the thread name.)
299032-BftD-haysville-haul-2025-33.jpg


Originally, my plan for this frame was to install this Shelby fork I have, bob the rear fender, and make a board track racer out of it.

299039-BftD-Firestone-Pilot-Rat-9.jpg


I still might do that later, but when I was gifted this Schwinn Cruiser for free last month, I hatched a new plan for this Speed bike. See, I got this bike for the fork, but the steerer tube is 6.5", 1/2 an inch too short for the bike I planned to use it on. So, I tried thinking of a bike in my stash that could use it.
299041-BftD-schwinn-cruiser-2.jpg


That's when I remembered that this Speed bike used a 6.5" steerer tube, and since the fork I want to use isn't coming off the donor frame anytime soon, I figured this would be the perfect bike to use that fork! When I ran by my storage space to drop off some parts and pick up some for my Build Off bike, I grabbed this frame and any parts that could come in handy for the idea I had in mind.

I mocked it up after dinner last night, and although the tires I mocked up were too big and I hadn't removed the skiptooth chainring yet, I could already tell that this bike would make a perfect klunker!

99034-BftD-UNPARALLELED-SPEED-klunker-1st-mockup-2.jpg


I threw on a small Schwinn chainring, and right then and there, I knew this bike was just what I needed to test my theory about low-gear single-speed klunkers!

Here's the plan: I want to throw this bike together before Saturday, because on Saturday is the Port City VW car show in Catoosa, Oklahoma. Not only is it a big car show, but it's also a big bicycle show as well! I even won "best in show" with my bike Shoestring last year and won a new Park Tool work stand, pictured above! I want to bring something new to the show this time, and since my RRBBO20 entry won't be ready in time, I want to bring this and ride it around at the show! Now, there is a chance that the show may get rained out, but even if it does, I still want to be able to bring it to my Dad's next cruise-in at his shop next Thursday. With any luck, I'll have it ready to ride by tomorrow evening, but we'll see how that goes. The bikes that "should be pretty easy to put together" have a way of being more difficult than I'd like.
 
As nice as the blue fork looked on this frame, I didn't want to spend any time and effort stripping and repainting it to better match the rest of the bike. Fortunately, I had this chrome fork I bought at the same swap meet as the frame, mocked up on another klunker I'd like to build.
299066-BftD-mockup-mash-42225-12.jpg


It looked good on that Colorflow, but that frame really needed a fork with a 7" steerer tube, not 6.5", and I'm not ready to build it yet as the frame needs to be repaired with some welding. So today, I took the chrome fork and stuck it on the CWC frame. While I was at it, I decided to see how the BMX bars would look on this frame as well. I was ready to just use the flatbars I had earlier, but those BMX bars just looked so much cooler!
99043-BftD-UNPARALLELED-SPEED-klunker-2nd-mockup-1.jpg


I didn't want to use those bars though, as those needed to stick with the Colorflow. I dug through my other bars, and found this old-school stem with black bars. The black bars weren't doing it for me, but I liked the older stem.
99044-BftD-UNPARALLELED-SPEED-klunker-2nd-mockup-2.jpg


I installed the bars that originally came with the stem, and I knew this was just what this bike needed!
99045-BftD-UNPARALLELED-SPEED-klunker-2nd-mockup-3.jpg


I also found this threaded hole in the bottom bracket, which I guess was for a chain guard. I'm not messing with chain guards for now, so I found a bolt that could at least fill in the hole for now.

I thought about trying to give this bike a more "period-correct" look with these rusty white wheels and Lightning Dart tires, but I just wasn't feeling it. I'm not really a stickler for that sort of thing, but on top of that, the front axle was just too narrow for the fork.

99051-BftD-UNPARALLELED-SPEED-klunker-2nd-mockup-9.jpg


I checked the frame's alignment, and fortunately, all I had to do was tweak the dropouts a little bit!
9052-BftD-UNPARALLELED-SPEED-klunker-2nd-mockup-10.jpg


I decided to use a set of later-model silver wheels with some new 26"x2.125" cruiser bike tires I got on clearance at Target earlier this year. Not only to they look good on this bike, but they should preform better than the older wheels and tires I thought about putting on before.

9056-BftD-UNPARALLELED-SPEED-klunker-2nd-mockup-14.jpg


The last thing I did was throw together a kickstand so I could pose the bike outside.

I've got to say, I'm really happy with this! I might still modify it and build it into a board track bike later, but for now, this is going to make a fantastic klunker! And it's the perfect bike to do my whole low-gear test with as well. I don't have to worry about painting it, as the rusty black paint and chrome looks good on it as-is. I might not even try to shine it up with rubbing compound; I'll just wash the dirt off and hit the inside with rust inhibitor! All I need to worry about is cleaning up the internal bits, like bearings, cups, races and wheel hubs, and then it's just a simple matter of putting it all together!
 
I'll keep the words to a minimum as it's 11:30pm, I'm tired, I want to go to bed, and I want to get up at a decent time tomorrow because I still have more more day left to get this bike done, and I'm going to need it. I'll just list the progress that happened today, then go over specific highlights as they come up.

1. Checked headset and bottom bracket bearing cups. The headset ones were okay, but the bottom bracket cups were iffy.
2. Washed the frame, fork, chainring, crank, handlebars and handlebar stem.
3. Wire-brushed chainring teeth, crank threads, handlebar stem parts, inside the seat tube and bottom bracket, pedal threads, bearing cups, and anything else that needed wire-brushing and/or steel wool.
4. Picked out pedals and handlebar grips
5. Cleaned up headset and bottom bracket hardware in ultrasonic cleaner.
6. Installed fork, handlebar stem, and seat post/seat.
299180-BftD-CWC-klunker-clean-assembly-1.jpg


Highlight #1: Either the headbadge is not original to the frame, or it was taped/glued back on after someone repaired and painted the frame. (More on that in a bit.)

299182-BftD-CWC-klunker-clean-assembly-3.jpg

299183-BftD-CWC-klunker-clean-assembly-4.jpg


Highlight #2: This frame uses Schwinn bearing cups. I'm fairly sure this is a CWC...
299184-BftD-CWC-klunker-clean-assembly-5.jpg

299185-BftD-CWC-klunker-clean-assembly-6.jpg


HL #Alyx: As I cleaned the frame, I found evidence of frame repairs with a lot of brazing. There's more besides the bottom bracket, but that's the biggest repair.

299187-BftD-CWC-klunker-clean-assembly-8.jpg

299188-BftD-CWC-klunker-clean-assembly-9.jpg


Highlight #4: Found the serial number under the bottom bracket. It's hard to read, but I think it says "Z 32721." Anybody know how to decode this?

299192-BftD-CWC-klunker-clean-assembly-13.jpg

299193-BftD-CWC-klunker-clean-assembly-14.jpg


Highlight #5: I also washed the fender that was bolted to the frame when I got it, only to find it was blue, not black. Looks like I'm not not using this fender on this bike for now.
299194-BftD-CWC-klunker-clean-assembly-15.jpg


Highlight #6: I guess this bike used to be green originally. Also, no holes from the rest of the frame connecting to the headset... Odd, but not unheard of.
299195-BftD-CWC-klunker-clean-assembly-16.jpg


Highlight #7: More evidence of repair, wear, and tear.
299196-BftD-CWC-klunker-clean-assembly-17.jpg


Highlight #8: My improvised wire-wheel setup for cleaning threads on bolts.
299197-BftD-CWC-klunker-clean-assembly-18.jpg


I almost put these pedals on my Schwinn klunker, since it has some non-Schwinn pedals, but two things kept me from doing that.
1. The pedals on my Schwinn klunker are much shinier than these, and fit the look of that bike better than these would.
2. I think it's funnier to stick Schwinn parts on a non-Schwinn bike, and vice versa.

Continued from previous post.

I ran into a substantial hiccup with the fork and headset setup. I wanted to use the crown race off my blue Schwinn fork on the chrome fork, as I planned to just use the Schwinn bearings and cups this bike already made use of, but the inner diameter of the Schwinn race was about a 1/2 millimeter to small to fit on the chrome fork. I found some other bearings and bearing cups that could work with the race that came on the chrome fork, but I really wanted to avoid that if I could.

I was hoping to install the bottom bracket today, but I need to find better parts for that, especially since one of the ball bearings had a massive gash in it.
299208-BftD-CWC-klunker-clean-assembly-29.jpg


Here's how far I got today. Not bad, but I still need to find, clean, and install the bottom bracket hardware, rebuild the wheel hubs, and install the chain.
299209-BftD-CWC-klunker-clean-assembly-30.jpg


Speaking of chain, I'm not sure what gear ratio I want to go with. The chainring's a 36-tooth, but I've got about 5 different sizes of sprockets to choose from. I was thinking of going with the 22t sprocket (especially for the slow drag race they have at the VW show,) but I'm wondering if I'd want something closer to a 2:1 gear ratio for regular riding. I can always change it after a bit of riding I suppose...

Frame is '35-6. The Schwinn parts will make it faster--kinda like chrome valve covers give you five more HP!
