I'm pretty new to working on old bikes, but I'm interested in taking on this challenge. I just recently bought a '87 Schwinn Le Tour and over the bike frame is great condition. The chain and rear cog are rusty though. It needs new tires and tubes, new handle bar tape and probably just a complete cleaning and regreasing/oiling.
Here are a couple of pics of the 87 Le Tour. I've included a picture of the Stong Light Crank, and the Freewheel. Should I be able to clean the cassette up, or does it look like a replacement is necessary? If I do need to replace it what type of Freewheel do I need to get?
I've started dismantling the Schwinn, and I have a couple of questions. Should I purchase the tools necessary to remove the crank and bb or leave that to a professional? If it's not that difficult what tools exactly will I need? I'd like to regrease the bearings and clean out all the old 27yr gunk.
While I was messing around with the cranks I broke the dust caps, are replacement dust caps for Strong Light crank arms easy to get or is there a compatible part?
Since I have taken the headset apart to clean the bearings should I just reuse the bearings or is it wise to replace them now? I also have the same question about the bearings in the hubs? Also is it possible to take the hubs apart with regular wrenches to do I need bicycle specific thinner wrenches?
I'm sure there will be more questions as I keep moving along in this project.
Thanks
OK, that's a freewheel, not a cassette, and the rust isn't an issue.
Remove the wheel, and if the freewheel spins backward with a nice watch-like clicking it's fine, though you might want to wick a few drops into the gap between the inner and outer body.
If it isn't smooth, sounds gritty or doesn't engage positively it can usually be saved with a good solvent flush and relube. This should be done off the bike so you'll need the correct freewheel remover. If you've never removed a freewheel get advice or read a tutorial because while it's easy, it requires lots of torque and it's easy to damage the freewheel or the remover.
The chain may be OK, and come back to life with some good chain oil. It's a judgment call as to how much rust is OK before the chain is dangerously weak, but older chains had thicker plates and therefore deeper reserves. If you're in doubt, or expect to ride steep hills, replace it, they're cheap enough. If you only expect easy riding in the flats or near the shore, you can keep it on safely.

What type of Freewheel tool do I need? It is a Shimano Freewheel. What about taking apart the BB, and removing the cranks? What tool (s) will I need to do that job?
I have decided to just replace the chain.
When I removed the old tires there was a steel band in them that proved to be rather difficult to get off. Ultimately I ended up cutting the steel band with a pair of dikes. Do I need to replace the tires with steel bands or will regular tires work ok?

You need one of two Shimano freewheel removers. Be careful not to buy a Shimano cassette remover which looks similar but is different. There are various sources besides Shimano; Park, Pedros and many others. The difference between the two tools are that the newer version fits over the axle, and the older one is smaller and requires that the axle is removered first.
I can't help you on BB tools, so you'll have to hold crossing that bridge until you get to it.
Your tire question worries me. All tires have wire or kevlar beads to keep them on the rim. The older steel hoop variety is usually easier to remove because it gives less under load, and so doesn't have to be undersized as much.
What worries me, is that you obviously don't know how to fix a flat, which is the most basic or bike repairs. based on that I strongly advise you to find a local bike repair class and learn the basics before you get yourself into hot water.
I think about this often when I post, am I helping someone, or just helping them to get in over their heads. In your case I suspect the latter.

Thank you for the back handed slap FB :) I'm actually pretty mechanical. I am a electrician by trade and work with tools daily. I feel pretty confident in fixing a flat, I could not get the dry rotted tires off in conventional ways. I almost believe that someone had previously squeeze/stretched whatever a smaller tire on this rim. The steel was extremely tight. I do appreciate your advice to find a repair class though and it is something I have considered.
Bikeman thanks for the links I appreciate it.

You will get up to speed pretty quick. A good book is helpful (unless you have a laptop with you in the shop). Park Tool's 'Big Blue Book' is good.
If you think you want to learn some bike mechanics and will use that knowledge in the future, then get the BB tools, you can definitely do the job if you're the sort of person who can carefully follow the steps in a book.

go ahead and count on replacing all the balls in the bb; headset and both wheels. They're cheap and it's not worth doing all that work and re-using old stuff. I would count on a new chain, bar tape, tires/tubes; cables/housings and possibly a seat. It's rare to find an original seat that old with out a rip or dry rot. If you do it all well; the first time through; you'll be much happier for much longer. Those Stronglite cranks require a specific puller to remove them. You can ruin them in an instant with the wrong puller.
Oh.....the bike DOES fit you......right? Doing all that work on a bike that is uncomfortable to ride is a real bummer after you sink all that effort in to it.
And read this site front to back.......

In no particular order:
Yes, dustcaps are readily available. Visit your LBS, there are lots of good ones in KC.
I just bought a nice pair for a buck apiece, metal with nice chrome finish.
There is no way that the tires were too small for the rims. What probably happened is that the tires were so old that they got crusty and pretty much "glued" themselves to the rims. I've seen it many times. The wheels on your Schwinn should be 27" according to the '87 catalog. There is no way that somebody forced 700c tires onto the rim.
Replace the chain for certain. The freewheel probably has life left. I typically degrease the outer surfaces and clean thoroughly then lube the inside as described above. Light motor oil dripped in the small gap in the outer margin of the front of the freewheel.
I have to comment on the cables. Did you replace the cables and housing? If not, do so immediately. The housing is WAY too long on the rear brake. Also, the housing going to the RD is a mess. It has pulled away from the ferrule and both looks bad and probably will cause mis-shifts.
Please don't get offended by some of the advice on here. We all had to start somewhere. But personally, I would recommend that you have the bb and the headset done by a local shop. My local shop will clean and repack the bb for $10.00 and the headset for the same or less. If you need new bearings, they just add the cost on top of the labor to remove, clean and regrease. Ask them is you can stay and watch.

I was waiting for this comment. It's not too long, it's just in the wrong position. See how tight it is up by the brake lever? It probably just needs to be pulled through the cable guides on the frame. I do agree that the RD cable looks awful though. All about cables: http://sheldonbrown.com/cables.html
Those Stronglite cranks require a specific puller to remove them. You can ruin them in an instant with the wrong puller.
I've never heard of this. Why won't the standard square taper puller work? I've never worked with Stronglight cranks before but would hate to ruin a set.

Stronglite cranks, at least the earlier ones, use a slightly larger diameter threading in the crank arm. Larger enough to allow the puller to thread in, but the threads will strip in an instant as soon as some force is applied, rendering the crank stuck to the spindle forever (or a really messy job of removing it). A bike shop should have the right puller- make sure they know what they're doing, tho- a lot of the kid mechanics have never even seen a Stronglite crank...

08-22-11, 11:45 AM
All of the cables and housing will be replaced. I currently have the bike in many pieces cleaning all the parts. It's hanging from a hook in the garage with the crank attached that's it.
Yes the bike fits me, and I am really anxious to get it out on the road.
It may be in my best interest to take the frame to LBS to have them remove the BB and crank arms.
Thanks for the tips
Cool build! I'm in the midst of doing the same for a 1988 Schwinn Super Sport.

Thanks! It is my first build, and I would actually call a rebuild since I'm not doing anything too different from how it was when I got it. What are doing with your Super Sport?
I had the Super Sport stored for about 20 years. I'm cleaning it up and trying to keep it stock. It has the original 600 (pre-Ultegra) components, downtube shifters, and Columbus tubing. I'm having trouble finding the old fashioned cup/cone/spindle style bottom brackets, so I may use a cartridge bottom bracket, square taper. The neat plus is I still have the original Shimano Biopace eliptical chainrings that were big in the late 80's. And the original mauve paint is in great condition. I like that classic steel tube look.

What kind of upgrades would some of you suggest if one was to change this bike into something I could do century rides on if wanted but also a more comfortable cruiser? I guess maybe not a racer set up? I would most likely only be looking for used parts, and relatively inexpensive if possible.
What I'm thinking is the changes really need to occur in either the stem or handlebars. Am I correct? Any other suggestions?

if the bike is working well, focus on things that affect comfort or position, and getting gearing into an optimum range. Other than wheels and tires, most "upgrades" have only marginal impact on speed and endurance. So save your money and work on getting the engine ready for the ride.

08-26-11, 10:16 PM
Yep most Stronglight cranks have a 23mm, and some TA brand had a 23.5 to further confuse the matter. Either way that crank was a HUGE upgrade from the crank that came on it. Consider yourself lucky, hehe. Relube ALL of the bearings on the bike, and replace the cables. Using a piece of indexed housing on the rear will make a big improvement on the shifting crispness as well. They used spiral(aka brake) housing on the rear originally. "Sometimes" it will shift well, and it "may" have shifted well when new, but indexed gears HATE brake housing! Use modern shifter housing, even though it seems like such a small length. Also replace the chain. Once a chain gets to the point of externally rusting it can develop one or more tight links, that will make it "skip" under load.
If you're doing anything other than going around the block a few times a month, get a cartridge BB. The smoothness is well worth it. Getting 30 miles into a metric century isn't the time to find out your BB is loose or crumbling to pieces.
One more tip: Switching to aero brake levers will geatly improve the braking power, as well as cleaning up the entire look of the bike. There are plenty of Shimano aero levers available on ebay, etc.
Good luck. :) I've rebuilt several of these late 80's Schwinn road bikes, and the ride is worth it. They were highly underrated then, and they still are now.

Suggestions for new stuff: the things you come in contact with on the bike. Getting good pedals, a comfortable saddle, and nice bar tape are way more important than any fancy add-ons. Of course, if you're happy with what you've got no need to change it. I second the aero brake levers though, because I agree that they really clean up the look of the bike.

I disagree. All my bikes but one have loose ball BBs. While they may have been in rough shape when I bought them, all are now perfectly smooth with fresh grease and 11 new balls per side. There's nothing wrong with a properly adjusted (and tightened) loose ball BB. The one bike I have with a cartridge unit is trashed, and since I can't simply rebuild it I need to fork over more money to replace it.
Bikedued
08-27-11, 08:10 AM
Aero levers clean up the look of the bike, that is the obvious part... The improvement in braking is by mechanical advantage. (1) The flex of the cable housing when the lever is pulled is eliminated, since it is (hopefully) taped tightly against the bars before the bars are wrapped. This is a less important issue than..(2) The way the inner cable is pulled in the aero lever.
On non aero levers, the downward motion of the lever is used to pull the cable. While it does work it's fairly weak, and requires a LOT of lever travel to complete the task at hand, which is stopping the bike. Aero levers use the fulcrum more efficiently, pulling the cable forward rather than down.
Most aero levers have a return spring as well, which improves the modulation(control) of the brake application. They also usually have a more ergonomic lever design so they feel good under your fingers. This is a minor feature, but it sure makes them more fun to use. Late 80's to early 90's Shimano aero levers are some of the most comfortable ever made IMHO. Something like these....

Loose ball bottom brackets are fine for normal usage, but require a lot of maintenance even with the attempts at "sealing" the bearings from moisture.
There is also the plain fact that no matter how much grease you stuff into them, most of it gets pushed out of the way pretty quickly. Probably in the first 20 miles or less. Cartridge BB's not all that expensive either? For a base model Shimano(which is still very decent) at the shop I work for is about $30, installed. Don't use your unwillingness to spend money as a way to talk someone out of a worthwhile upgrade? How old is this bike with the trashed cartridge BB? I am guessing 10-15 years old?,,,,BD

Most likely a 68 x 115mm. give or take a few millimeters. 68mm is the width of the shell, which is the measurement for MANY bikes aside from some Italian or fairly modern mountain bikes, which use a 70 or 73mm respectively.
The 115mm is The length of the spindle that the cranks mount to. You might could get away with one a little narrower than what is on there. As long as the inner chainring clears the chainstay by 5mm or a little more, you should be okay. You have to account for flex when you're out of the saddle, in both the cranks and the frame. The shop may not want to experiment with different spindle lengths though, to find a good compromise. If the inner chainring isn't touching the frame, or way the heck out there, you can probably use the same length in that case. The crank dictates the length of the spindle, not the frame. Some cranks are inset to the point where you'd need a 122 or even longer to give enough clearance.,,,,BD
Look at the BB shell. If the "cups" are inset and have a bunch of little splines, then you already have a cartridge style. I am betting it's a traditional though, with a lockring on the non drive side.

Has anyone ever tried taking a angle grinder with a wire wheel to their freewheel to clean off the rust? I have been able to clean the rust off the 3 smaller cogs but the rest are being rather difficult. I still have not removed it from the wheel but tonight I just cleaned the rear wheel really well so any more major cleaning on this freewheel will have to come after I remove it.
If a angle grinder is a bad idea. What product should I be using on the freewheel while I scrub the crap out of it with a wire brush. I used WD40 on it the first time and like I said was only able to clean the smaller 3.
Thanks again for any advice!

I've never actually done this, but it doesn't seem like a bad idea. The wire wheel shouldn't take off much material, which would be the main concern.
Honestly I wouldn't bother. If I come across a rusty freewheel or cassette I just shoot it with WD40. Many of them are brown in color to begin with, so it makes little difference. The surface rust on your sprockets really doesn't negatively affect how they function. More important is how clean they are.
If the freewheel is really that bad (doesn't appear to be in your photo) then no amount of work will revive what the rust has done. At that point, it's time for the trash pile.

Sprockets are similar to railroad tracks, the chain will clean up and polish the area that needs it, and the rest doesn't matter.

I was able to give the bike a test ride up and down the street tonight. I completely took it apart and greased/replaced all the ball bearings, hand cleaned every part. I will take some pics of it when the new hood covers get here.
The question I have today is what are my options for upgrading the brakes. These diacompe brakes suck. It may be that they still need some more adjusting but they don't stop very good. BTW I did replace the brake pads.
Bikedued
10-16-11, 09:13 PM
It's more than likely the pads are dry, or need sanded. See if a screwdriver tip will dent them. If it will, remove them and run the braking surface on smooth concrete, a file, or sandpaper until the "glaze" is broken. Dia Compe made pretty good stuff, but your pads
do the actual stopping.,,,,BD
FastJake
10-16-11, 10:04 PM
Some of the Dia-Compe single pivot sidepulls from the 80s are absolutely horrible. My parents have a pair of World Sports, and the brake arms on their bikes are so flexible I'm surprised they were put into production.
Yours might need more adjustment (most poor braking is the result of poor setup) or your brakes just suck. Try this test: stand over the bike and hold the front brake. Try moving the bike forwards and back. If you can see the caliper flexing a lot like I can with my parents' bikes, I'd recommend replacing them.

Yep, those are the nicest road brake levers I've used by a long chalk. Pair them with a Shimano dual-pivot front brake of almost any description, something like this (http://www.ebay.com/itm/NOS-Shimano-600-Brake-Caliper-Set-BR-6207-/250891500757) on the rear, maybe a set of nice pads (should be optional), and experience the best braking you'll know via cable and rim.
if the bike is working well, focus on things that affect comfort or position, and getting gearing into an optimum range. Other than wheels and tires, most "upgrades" have only marginal impact on speed and endurance. So save your money and work on getting the engine ready for the ride.Yep, I'd say,
1. Position (minimise frontal area while maximising biomechanical advantage - you can expect to be able to improve this over time, to get your torso further out of the breeze and put more pre-stretch on your glutes; you may want your bars lower at some point)
2. Tyres (not such a concern for 700c, but an issue for 26" on the road)
3. Gearing (you don't want more range than you need, because you want your ratios as close as possible)
4. Rim weight (heavy works fine - better, even - if your speed is almost always close to your average speed, and you don't climb, but feels yuck next to light)
And the rest is incremental.
Although some upgrades make a lot of difference - an aero bar (really comes under position) is good for an extra gear (feels crap and hurts responsiveness, BTW).
And brifters are really where it's at, IMO - you shift a lot more often, which has to factor into the aforementioned speed and endurance. Also, I reckon they're safer on the street.
Bikedued
10-17-11, 07:54 PM
Aero bars I'd only recommend if you can get the type where the aero position can be set back. IE: pads behind the stem. The ideal aero position for most ends up with the forearm pad behind the upright section of the bar. If they aren't you may end up having to get a shorter stem, and comfort on the hoods and drops will suffer.
I like brifters for convenience in group rides, but they just plain do not fit my hands well.,,,,BD

I have a question about the headset nuts. When I took the bike apart it had a reflector on the front. The reflector had a ring that fit under the headset nut. When I put the bike back together I didn't reinstall the reflector. It feels like there is a bit of wiggle in front area and I'm wondering if I need a spacer in the place that reflector ring was? Everything seems to be tight but I don't know if there still may be a gap there.
Thanks!
FastJake
10-30-11, 12:44 AM
If it's wobbly you either need to put the reflector back on or get a spacer to replace it. What's happening is that you're bottoming out the locknut on the steerer tube so it's not actually doing anything.
You could cut a tiny bit off the steerer tube to solve the problem, but that would be really stupid.
Thumpic
10-30-11, 07:31 AM
DON'T CUT ANYTHING!!!!! THIS IS VERY BAD ADVICE!!!!!
The reflector does not have any function in the tightness of the head set. It is simply a reflector. Be sure you have the other components in the right place. On the top of the fork crown is the lower race of the lower bearing....then you'll have the bearings.....if they are the "caged" type, be sure they are installed the correct direction....then you have the upper race of the lower bearing.....it is press fit into the bottom of the steerer tuber..then look at the top of the steerer tube......you have the lower race of the upper bearing; it is press fit into the top of the steerer tube.........then you have the upper bearings... and then you have the threaded upper race which is usually the adjustment cup as well. Everything else goes ABOVE the adjustment cup. The reflector may or may not go between the lock nut and the adjustment cup; it depends on the design of the head set. If it (or another washer/spacer) does go there; I suggest using it. It makes the final adjustment of the headset (your wiggle) much easier.
Look and read here for more info.....I included an excellent pic from Sheldon Brown's website...

I am fairly certain I have everything put together and all the parts installed with the exception of the reflector that may have also acted as a spacer washer. So can I buy just a spacer washer? Is this a bike specific item or something I could get at the local hardware store?
Thanks for the graphic Thumpic.
Thumpic
10-30-11, 09:51 AM
Even if it acts as a spacer it won't create or affect the wiggle. That is corrected by adjusting the threaded upper race. Assemble it with the reflector and see if the wiggles goes away. If that's it then leave it on. If you just can't stand the idea of a reflector, cut off the reflector and grind the spacer portion of the mounting bracket into a nice round shape and use it. It's probably got an alignment tab that fits in a slot on the fork. You won't find one at a hardware store.
FastJake

Yes it can. Remove the locknut from a threaded headset and see if it wobbles. The upper threaded race alone is not enough, the locknut keeps everything solidly in place. If the locknut is bottoming out on the top of the steerer tube without the reflector/spacer it is essentially not doing anything at all.
Also note that I didn't actually advise the OP to cut the steerer tube, hence the "really stupid" bit.
OP: if you don't like the reflector any LBS should have an appropriate spacer to replace it for a couple bucks.

What you are saying is that the fork tube is not threaded far enough. I have rebuilt over 200 bikes (not as many as some) but I've never seen a fork that was not threaded enough to cause an issue like this. You're right about the lock nut keeping it all in place; but the adjustable race is what controls the headset tension; nothing above it plays a role in that adjustment at all. Of course if you TIGHTEN the adjustable race while TIGHTENING the lock nut; you have changed the tension on the bearings and you would have an extremely tight headset. The reflector bracket probably acts as a washer between the lock nut and adjustable race; but it still won't affect the adjustment cup and the "wiggle" of the fork.
I use truvativ cartridge BB's in my older bikes, just b/c they work well and are so simple to install. Cheaper than shimanos, and no plastic cups either, both sides aluminum. THat said, the loose bearing BB are sweet if you don't mind the initial build of them and getting greasy. My loose bearing BB will outspin any of my cartridge units with no chain on. Don't notice it on the bike, but sure feels more free by hand. But probably b/c there's no seals dragging anywhere. You can take the freewheel apart if you screw it to a board and have a chainwhip and you really want to clean it up. But that's ALOT of work for something that doesn't matter. WD40 the whole thing then wire brush it, and call it good. Nice bike by the way :) Love old roadies! I've used BB's from 108 to 118 on my old bikes depending on the crankset.

What you are saying is that the fork tube is not threaded far enough.
No, this isn't what I'm saying at all. I think we're just suffering from some misunderstandings here, but I'm still not sure.
The locknut on a threaded headset is capped at one end. It cannot be installed upside down and if you install one on a bare fork (without a frame/headset/etc.) it will thread onto the fork then bottom out. This is what I suspected was happening to the OP. The fork became "too long" when the reflector bracket was removed, therefore making the locknut useless.
Imagine a fork that was threaded the entire way but was way too long for the frame it was intended to be used on. Every part of the headset install would go perfectly fine except for the locknut. This is what I think happened to the OP, just on a much smaller scale.

Well.......as I don't leave off reflectors, I'll just chalk this problem up as something I have never seen.....all I know is that if a head set wiggles; 99% of the time the adjustable race is not adjusted correctly. I can perfectly adjust the headset (no wiggle) while the lock nut and reflector are still on the bench.
Good luck... :)

Yes you can tighten the bearings without the locknut, but it will stay that way for about a block of riding. If the washer and top nut are not hitting the upper race, then you need more spacers between them.,,,BD

I stopped by a LBS today the owner is an old school road racer, and mechanic and he confirmed that the reflector does indeed act as a spacer and that my lock nut was most likely bottoming out. So he sold me a spacer and now I'll be able to remedy the problem.
Thanks for all the replies!

Yes the reflector had a function. I remember my LeTour quite well. The reflector mount ring had a key section that fit in the grove in the fork. Basically it was a spacer that was included in the "stack" of the headset. You need to put the reflector mount back on or get a spacer with the key to replace it.
