Single Speed Fixed Gear Conversion

Schwinn World Fixed Gear Conversion - Bicycle Before

I am currently working on a vintage, very desirable frame and bicycle restoration.  That frame needs a new paint job and I am still searching for a few more original components.  At the same time that I am stripping and painting that frame i am stripping and painting three other frames.  This saves clean up time and prep time, basically getting all the dirty work done at once.  This post is not that desirable frames story, this is one of the other three, but all will eventually be posted.

This summer i have gotten a lot of requests for converting less then desirable bicycles into single speed and fixed gears or requests for repair or just plain getting the bike working repairs on single speeds that where purchased for way to much on Craigslist.  These Craigslist conversions where usually very poorly done.

I do want it to be known that i also have turned down a lot of single speed conversions to bicycles that where just to nice to convert, I do not believe these nice bicycles should be converted, rather unwanted poor condition bicycles should be to bring them new life.  I turned down a gentleman that wanted a single speed conversion done to a Raleigh International, I also turned down a gentleman that wanted a Falcon San Remo that was is very nice condition.  I am sure someone ended up converting these bicycles, but it was not me.

I recently came across a very beat up Schwinn World that the components where very poor quality and damaged, paint was chipped and rusted but the frame was solid and straight.  This Schwinn World is a single speed / fixed gear candidate.  I also want to show how a good conversion should be done.

I started by stripping the frame off all components and then stripping the frame of paint.  The components that will be reused are the frame, fork, headset, stem and bottom bracket.  These components are actually fairly descent quality and can be easily restored I am also considering the brake calipers as they are descent quality but I will have to see how well they restore before deciding.

I will be adding a quality flip/flop rear wheel, a quality front wheel, a true track crank, pedals, true track handle bars, and cross brake levers.  I am adding brakes because I do not know who will purchase this bicycle and they can decide if they want single speed or fixed gear and brakes or no brakes.

The paint scheme will be red with a cream colored head tube.  I have always liked this combination of bright color and cream head tube, it is a little bit of a classic throw back look.

With the frame stripped of components it is time to strip the paint.  I do not have a media blasting cabinet yet, it is a winter project, the shop has just been to busy this summer to devout time to it.  I used spray on paint stripper and laid out tarps to capture as much as the mess as I could.  It is very important to wear eye, skin protection and a breathing respirator while stripping the paint.  The paint stripper burns skin and if not careful, burns badly.  The paint stripper does do a good job at removing the paint.  The paint peels away like a snake skin and a Brillo pads cleans the rest.

With the paint stripped from the frame I use a wire wheel in a high speed drill to remove any last specs of paint and to give the frame a good cleaning.  Below is a photo of the frame and fork stripped of paint and cleaned with the wire wheel.

Next I am going to remove the rear derailleur cable stop and the down tube stops.  I do this with a cutting wheel and then smooth it out with a hand file and sand paper.

With the cable stops removed I sprayed as much of the inside of the frame tubes that I could get to with a a rust inhibitor.  It is a little bit of a messy thing to do because it does drip out of the tubes but it is well worth it because for a $3 can I can spray five or six frames and it does help protect the frame from the inside.  Also to toot my horn so to speak, it is part of quality work and and easy thing to do when the frame is stripped, but most do not think to do this.

After the rust inhibitor drys I then clean the frame very well with alcohol and it this point i will only touch the frame with gloved hands to prevent oil from my skin preventing primer and paint from sticking well.

That is where the fixed gear conversion is as of today, check back later.

I have had a lot of full paint restorations recently so I have been painting the fixed gear conversion as I go.

I left of with the frame ready for primer.  I am paint the frame kind of a slightly darker throw back red so I primed the frame in a sandlable red primer and then baked the primer for a short time in my small heat box.

The primed frame needed only a little wet sand to smooth out a few spots.  I sprayed the frame and fork with the the cream color on the head tube in my paint booth.  My paint booth is made with 2x2 wood strips and 4 mm clear plastic and a very strong fan and duct work out a window.  Its not perfect but very effective for maybe $100 in materials.  The booth is about 6 feet by 6 feet, enough space to hang a frame and fork and move around.

My heat booth or box consists of a brick wall and a movable sheet metal and insulation 3 sided box that I can slide over the frame against the brick wall with a fan blowing fumes out the window and a heater.  It is very effective and does not cost much.  It really does not take much to bake paint hard.  Great paint jobs does not come from fancy expensive equipment but rather knowledge and preparation, it all in the preparation from wet sanding to proper dry times to polishing.

Taking time in taping or masking is part of a great paint job.  I masked out the area for the cream colored paint. I have seen people say that this is not a real necessity for the first color going down but I do it because I don't want the lug lines to get thick and have other paint lines to sand out.

Today I sprayed the red, one light cote and bake to make sure all was smooth and then the second coat and bake.  The red looks fantastic but I will still wet sand some area for best finish.  Next will be clear coats and final wet sand and polish. The photos below are right out of the heat box and moved with gloves.  The white fork in the red fork photo below is a fork I heated at the same time as the red fork and frame and is for another project.

The photo above of the frame bottom bracket, it looks like the threads of the bottom bracket have been painted, technically they have but I layer a thick coat of grease over them before paint and easily wipes off when all is final and cured.  Its a lot easier then masking the threads off.  The masking is tricky on the threads to get a good paint line and never sticks well.  So tip of the day!

Next comes the clear coat, wet sand and polish.  I have some fantastic wheels on order for a good price. They will have a flip flop hub.  I also have true Soma track drop handlebars with a true track geometry. Should be a beautiful bike!!

1982 Schwinn Superior Preservation

1982 Schwinn Superior - Updated April, 2014

1982 Schwinn Superior - Preservation

Recently my friend Dave may have come across the find of a lifetime.  A 1982 Schwinn Superior in museum quality condition.  It did need a good cleaning and a repacking of the bearings, other then that it needed nothing.

The history of the 1982 Schwinn Superior is fascinating and thanks to some research and a phone call by Dave some details about its history that is little known has been uncovered.  The 1982 Schwinn Superior is quit a bit different the the previous 5 or six years of the superior line and part of the 1981 line.  Schwinn at the time had a hand built division that built the Paramount line and a few other bicycles along the way, the quality of that division was starting to become poor and Schwinn shut down the division and eventually moved it to Waterford, Wisconsin.  There was some tubing and lugs left over from the Paramount, to use up the materials Schwinn built up the frames and put the Superior name on them.

There have been many speculations where the frames have been built, I have seen people speculate Chicago, Japan, built by Panasonic like other Schwinn models but thanks to one little blurb mentioning a name and a phone call by Dave to this gentleman that was in the blurb a lot has been determined.  The blurb mentioned a name and that the frames where outsourced to a small company and built by two frame builders in Racine, Wisconsin.  Dave looked up the name in a Racine, Wisconsin phone directory and found a phone number.  Dave called the number and talked to the actual frame builder, he is now 81 years old, retired and more than happy to discuss the frames.

One side note, after some Research I lived a few blocks from the Gentleman in Racine from 2004 until recently.  I wish I knew then, I would have walked over there sometime ago.

Through this gentleman Dave learned that this gentleman was told that his frames are the best frames Schwinn ever had made, that even today a few people in the know can spot these frames when the frames have been striped just by the brazing and quality.  The bare or raw frames where then sent back to Schwinn for painting and assembly.

The gentleman also told the story that when they closed down there shop in Racine, Wisconsin in the early 1980's Trek in Waterloo Wisconsin purchased all of there equipment.  I can not confirm this story, he did mention that Trek was still working out of a barn at the time.

The 1982 Schwinn Superior frame is built with Reynolds 531 tubing and Nervex lugs, the same tubing and lugs of the Schwinn Paramount.  The lugs are beautiful, the same intricate detail and swooping points of the Paramount.  Older Superiors where not lugged frames.  Two difference from the Paramount is that the chainstays are longer on the Superior and the Paramount frame was chromed and left the lugs chromed.  I own a Schwinn Volare, the Japanese Paramount, the Volare has a chromed frame and lugs.

The Schwinn Superior is equipped with a Campagnolo Gran Sport crank set, Campagnolo Gran Sport derailleurs with Gran Sport shift levers, Campagnolo wheel hubs, Campagnolo Gran Sport brake set and levers and Campagnolo Gran Sport pedals and clips.

Dave Schwinn Superior happen to come with an original Jim Blackburn rear rack, original Blackburn racks say Jim Blackburn not just Blackburn.

I am absolutely dumbfounded by the condition of this bicycle, it took a very light careful cleaning to remove the 30 years of storage dirt and new grease.  The old grease was perfectly clean except it was old and sticky.

The paint is spectaular, the Orange pearl Schwinn had is already my favorite color of any bicycle, but to see it in new condition and shine is amazing.  The pearl just sparkles!

Photos are below, I do not have many before photos because the Superior is in such amazing condition there really is no before and after.  Nothing has been polished on the bicycle, all is being left as is. The bearings have been packed in new grease and the cables have been replaced as the old where rusted and bent.

Thanks for looking,
John Z.

Update April, 2014  

Dave has really put a lot of work into his 1982 Schwinn Superior to dial it in right where he wants it.  He has added a tall Nitto stem, I think new Nitto handlebars, new leather handlebar tape with twine, a Brooks saddle, new brake lever hoods, new Ruffy Tuffy tires, new pedals that i have to look up again to get the name right, a cool knob for connecting a light to the fork and an awesome trunk bag from Rivendell.  Great job Dave, looks fantastic!!  I am extremely jealous!!
