Subject: How do you clean "Gum Wall" glop from rims?
|
I have a friend who has an old Schwinn Collegiate. He wants to ride it
again after leaving it hang in the garage for decades. The gum wall
tires have degraded and most of the residue has stuck itself to the
inside and outside walls of the rims. I tried cleaning it off with
mineral spirits and scraping it with a plastic scraper. After an
hour's work the front rim was clean enough to accept a new front tire.
What ideas do you have to save some time/work in getting the rear rim
nice and clean without damaging the chrome of the steel Schwinn rim?
Thank you in advance for any helpfu ideas.

The Varsities sure did! I think my neighbor had to use a bmx brake on
his fixed project. 70mm or something like that in the reach
department. With a conversion to 700c, we're talking a brake pad lift
of around 15mm, which is rather daunting. Especially as I think the
Collegiate's reach isn't as generous:
http://www.flickr.com/photo_zoom.gne?id=15563521&size=o&context=set-370373
With the fenders, I doubt you could go 700c, and you'd likely have to
swap out the calipers, not the biggest deal in the world. Without
fenders, which is a shame, I'm pretty confident you could make it work
Here, I've built a Sachs Torpedo hub onto a 700c MA3, on a bike that
was formerly a 590mm traditional 3spd size. I'm running 28mm tires,
and the fender clearances are stupid tight, just a couple mm's. It's a
great sleeper I found in a dumpster--there's nothing like challenging
guys on flyweights to a sprint when you're on a rusty orange German
girlie bike. :-P

Isn't the real problem going to be sourcing tires other than the
pretty nasty riding Kenda gumwalls? I mistakenly thought the
Collegiates came with 27" before, and that would have been a blessing.
In this circumstance, unless one is doing a historically perfect
restoration, switching to something a little less obscure would give
many more tire choices. Even the old 590mm standard has far more
interesting tire choices than 597. However, if it's about keeping it
simple, and if the Sun rims can be sourced inexpensively, a quick
rerim and installation of some Kendas is the way to go.
Considering the wheel size, it all seems much to much of a PITA to me,
unless the bike has sentimental value. I'd hit Craigslist and yard
sales to find something better to start with.

I was thinking 590 mm, not 597: 26 x 1 3/8 or 650A nominal size. I
have no idea what's out there for the 597 (26 x 1 1/4 to most others or
the Schwinn 26 x 1 3/8 S-6 rim).

I've check to see if 27" or 700C could be made to work- those old
Schwinns often had gigantic clearances.

Dear Andrew,
Here's a Schwinn serial/date guide:

We spin the wheel and use a screwdriver as if it were a lathe tool
agains the rim. quick and dirty but solvents take forever - more shop
time than a Collegiate is ever worth.

Paint stripper might work. Paint it on and let it sit for an hour or two.
Then there's duct tape - in the words of the immortal Red Green "Spare the
tape - spoil the job!"

This is good advice. Using the advice from Jim Langley's excellent
website (www.jimlangley.net), I cleaned my first set of tubular rims
using a CycloPro cone wrench applied to hardened glue on the surface
of the tubular tire bed.
There's a wrench for everything ~ but not necessarily everything the
maker intended !!!

Steel wool soap pads work fine, as chrome is pretty hard. That said,
the best thing to do would be to re-rim with alloy rims and some nice
tires. I've mentioned way too many times how pleased I am with the
Alex X404s shod with Vittoria Zaffiro 27x1 1/4 tires on my Sprite,
probably because I ride it in flip flops a lot this time of year, but
I'll mention it again. Only about $50 to do the switch, and it'll
brake great and ride wonderfully. This of course depends on the inside
diameter of the rim being a close enough match. Once thing I
especially like about the profile of the X404 is that it has a bit of
a Westwood rim style, a bit of an obscure homage to those geeks in the
know.

I thought it was BSD 597 too, but after a second trip to the loca
bicycle shop that sells tires for older Schwinn, I found out they ar
630 BSD on this Collegiate. I have a Collegiate of about the sam
vintage (mine has chrome fenders) that is 597 BSD. My friend'
Collegiate has matching green fenders, rim wall generator, front/rea
light, but his rims are 630 BSD and 27" tires fit perfectly.
I wish his Collegiate were worth more, but I will see what he does wit
it. He is recovering from his 3rd heart surgery. He thinks tha
bicycle riding will extend the qualtiy of life. I want to encourag
him without raising to many expectations or spending too much more tim
and money. $44 for new tires and tubes was sticker shock for him.
I was hoping someone would tell me that they used fingernail polis
rmover (Acetone) or "Goo-Gone" and the goop came off in a minut
without scratching anything.. Oh well, so much for those hopes.'
We tried the steel wool and Brillo Pads too, but didn't see muc
happening to the stuborn goo.... but the chrome looked brighter

Acetone as a last resort.
Xylol, toluol, and hexane (rubber cement thinner) are worth a try.
I keep cans of all four around the house for these kinds of jobs.
Methyl ethyl ketone enjoys a good reputation
for removing stubborn stains.

Hmmm. Mystery bike, eh?
Generally Suburbans are 27-inch and painted mudguards. Collegiate EA1
with chromed mudguards. What year is it?

You are right again!!! Boy, is my memory getting worse... or maybe th
power of suggestion is dealing me dirt.
It is a Suburban with painted mudguards.
I forgot to look at the year information because I was busy trying t
make the 27" Kenda brand tires fit smoothly on the Schwinn steel rims.
I didn't have much luck. The tires seem to be very lumpy and neithe
radially or laterally true. I gave up after trying about 5 differen
methods and orientations to get the tires to fit.
The rims are nice and clen now, but I don't plan on investing more tim
on this particular bicycle unless there are worthwhile lessons yet t
learn.
Andrew:
Thank you again for you help and guidance.

The 1971 through 1975 Chicago steel rim bikes have 'rim issues'. I built
the 1971/2 bikes new out of the carton when it wasn't unusual to find
tires blown off the rim on opening a new bike. There are both over- and
under-sized rims, either of which can wreck your afternoon.
Ensure the rubber rim liner covers the nipples but doesn't occlude the
lip where your tire seats. Scrape off any extraneous rubber detritus
that's on the seating lip. We spray Pledge on a spinning rim before
mounting the tire*. Air to 20-30 psi and spin to check that the molded
line just above the brake surface is clearly visible all around. Pull up
low areas with your hands. When it's even, air with confidence to 85~90 psi.
*car tire shops use soapy water. Spray wax is less messy.

Well, maybe it's more of a my memory problem than a mystery.
I don't know the year, but I see more value in the 27" wheel situatio
than my old 597 mm Collegiate. I will check my memory when I see hi
bicycle again. I will also look at the Serial Number to see if I ca
get the year.
I will check with him tomorrow to see if he is ready for the "scrapin
steel screwdriver and spinning wheel solution". I know I wasn't read
to use more solvent or plastic scraping after an hour.
BTW are there any nice & REASONABLY price aluminum 597 mm BSD rims?
I have been tempted many times to upgrade the old beast

I believe the Sun CR-18 is available in a 597. You can check with Jim
at Hiawatha Cyclery in Minneapolis as he rebuilt a set of wheels on his
3 speed with aluminum 597s. I think he said he has a pair of rims in
stock, IIRC (hopefully it's not some other wheel size entirely and my
memory is faulty again...).

Probably not, as the classy Raleigh RRA, Lenton and similar tourers of
the '30s through '50s used EA1 597 aluminum rims - they are highly
desirable and hard to find.
Changing to EA3 590 will be a little better and the brake usually spans
a 590 rim; if not, a longer caliper is under $20. It's still a real
project on most Collegiates. Your 27-inch bike can use cheaper standard
K2 630 wheels, about $40 each. That's a happy situation by comparison.
I know there are better Schwinn date guides but I can never find one so
I called Richard Schwinn a few years ago and took notes:
http://www.yellowjersey.org/photosfromthepast/schwinumber.txt
Dear Readers: that should not be construed as an invitation to call him
up and ask about a given bike - he has a pretty full plate nowadays.

Your description matches what I faced with a long-stored bike that was given to
me. It's also a Schwinn but with alum. rims. While the tire rubber was dry and
crumbly, for the most part, a significant amount of goo adhered to the rims. I
tried a little laquer thinner, rubbed on a small affected area with a flat piece
of pine. A new wooden paint stirrer would probably work as well and is easy to
acquire. Thinner didn't work as fast as I had thought it would, so after a
short time I decided to abandon it and use just the wood and water. The water
acted to keep displaced goo from re-adhering. There's probably a better, faster
method but what I describe here worked in the end. That was 2-3 years ago and I
don't remember how long the job took but I'd guess a couple hours per rim.
