| I don't think the Vetta chain cleaner is up to the abuse you're
heaping on the chain. It's quite thin, and water goes right
through it. You should try the thick goop that comes in small
green plastic containers called "Phil". This resists most
anything that you throw at it -- but be aware that it picks
up quite a bit of dirt, so you'll have to clean your chain
frequently.
I recommend using the Vetta unit to clean your chain, and then
applying the Phil goop before you go riding.

927.2 | Phil os okay, but paraffin wax is better. | SMURF::BINDER | And the quarterback is *toast*! | Mon Nov 28 1988 21:14 | 48 |
| You're getting tight links because your chain is picking up crud, and
the Vetta oil is probably aggravating the problem by wicking the crud
into the chain. This just doesn't happen nearly as much on a road bike
because there isn't as much crud to stir up.
Take note that the Phil product mentioned in .1 is *not* Waterproof
Grease - it's Tenacious Oil.
Paraffin wax is a better way to lubricate and protect an off-road chain,
though, because it's not "wet" and sticky. It won't pick up crud nearly
so rapidly. What follows is the procedure for paraffining a chain -
it's something you should seriously consider doing outdoors, or at least
in an open garage.
Clean your chain with the Vetta thingummy, then take it off and reclean
it in a solvent. Clean your chainrings and freewheel cogs so you won't
contaminate the wax.
NOTE
Xylol is the best solvent I know for this purpose because
it is absolute *hell* on any oil or grease; and it's highly
volatile so that it evaporates quickly and cleanly. It's
also hell on people - it's rather more toxic than most other
common solvents. Use it with *good* ventilation, and that
admonishment to avoid breathing the fumes means what it says.
You can get xylol at paint supply stores.
With your chain *really* clean, immerse it in a pan of melted paraffin
wax (300 degrees F, 149 degrees C) for a full 10 minutes. Keep the wax
away from heating coils or a flame - it'll ignite and make funny black
charred patterns all over you and anything else nearby. (This sort of
pattern isn't considered fashionable on even the wildest mountain bike.)
Your "Fry Daddy" cooker is the ideal tool here, but factor in the
necessity of replacing it when your non-cyclist significant other finds
the taste of wax objectoinable in the next batch of chips. Take the
chain out and hang it to let the wax drip. Reinstall the chain, then
spin the gears to free the chain up and allow excess wax to flake off.
Do this about every 300 miles, or when needed. You don't have to use
the xylol every time, because the paraffin will wash the small amount of
accumulated grit out.
As a side point, you shouldn't need a chain tool to free up a tight
link. All you need is to hold the chain on either side of the tight
link and flex it laterally back and forth.

927.3 | Ditch the Uniglide, buy a Sedis | RDGENG::MACFADYEN | Roderick MacFadyen | Tue Nov 29 1988 04:27 | 12 |
| re .0: Yes, I think it's significant that you're using a Uniglide
chain, because I think that the basic Uniglide at least is no good. I
used a Uniglide chain last winter on my touring bike, which I was using
for commuting, and I was getting the same tight link problem all the
time. No amount of cleaning and LPS3-ing seemed to cure it. But buying
a Sedis chain did, and that's what I recommend you do. Sedis is fully
compatible with Shimano index gears, I've found.

I had the same problem with a once new rock-hopper!
I took the bike back to were I purchased it, got a
new chain and that was that.
If your bike is new (no more that a month) get a
differant chain put on the bike for free.

I dunno so much, Rod. I've been using "gold" colored Uniglides on my
road bike since maybe 1978, and I have never had even *one* tight link.
I suppose that the brass plating on alternatem links could make these
chains less prone to tighten up than an ordinary blued chain.

| Re -1: I take your point, that's why I qualified my condemnation to
"the basic" Uniglide. I used a black (blued?) chain, called the
Uniglide II, costing about the same as a black Sedis chain. If you've
found the gold-coloured ones to be good, then I'm sure they are. But
they cost a little more, no?
Anyway, most chains aren't expensive enough to be worth the hassle
of putting up with sticky links every time you go for a cycle.

| I agree with Rod. Throw away the bad chain and get a new Sedi.
The same thing happend to me with my road bike this year, and after
it drove me crazy I went out and bought a cheap Sedi-sport. It worked
great on my SIS, and it only cost $4.50. I wish I had bought a couple
at that price.

927.9 | howabout Regina SL? | USMRM5::MREID | | Tue Nov 29 1988 11:16 | 7 |
| I guess I'll change my chain!
I have a new Regina SL chain (hollow bushings - lightweight) hanging
around. Any idea how this chain would hold up in off road use?
Maybe I'll give it a shot & if that doesn't work, I'll try a Sedis...

927.10 | Regina Yes, SL 50 No! | USWAV7::CLELAND | Speed is the essence of mayhem... | Tue Nov 29 1988 13:14 | 11 |

I would highly suggest you save the "Super-Light" chain for
a cherished road bike. I'm not a representative of Regina, but
I can state that the SL 50 chain was NOT designed for off-road
use. For flying over 6-foot diameter tree trunks, use a solid
chain, with real bushings, and flat link-plates (non-uniglide).
For lubrication, listen to the people who've already addressed
this topic of discussion, I never knew there was a science!
Maim some more dirt trails,
Good luck.

927.11 | If is shifts smoothly, dont clean it! | MAILVX::HOOD_DO | | Tue Nov 29 1988 15:07 | 50 |

I have two mountain bikes, (Stumpjumper and a Sierra), and have
had every type of chain problem imaginable. I have several opinions
which run against the grain of previous replies, but here goes...
1) when I clean my chains, they get tight links like crazy.
Don't ask me why, I really dont know. What matters is that
EVERY SINGLE TIME I CLEAN A CHAIN, IT GETS TIGHT LINKS.
2) Once you develop tight links, it is a bear to get rid of them.
I think that if you were to mark those links, you would find
the same tight links every time.
3) When a chain is working smoothly, DON'T CLEAN IT. A freewheel
costs only a few dollars more than a chain, and a dirty
chain is not going to wear a freewheel down that quickly. Note:
this is an observation made from several thousand miles on
a mountain bike. You'll break more teeth on your freewheel
from shifts in rough situations than you'll wear down with
a dirty chain. Some people will say: a clean chain shifts
more smoothly....and it's true, but you won't notice a
TREMENDOUS difference. What will drive you crazy is
A CHAIN WITH LINKS THAT STICK. This is *far* more important
on a mountain bike, and will make riding rough terrain
difficult. You'll spend more time missing shifts and walking
from a clean chain that sticks than from a dirty chain that
doesn't. So if you're chain is shifting smoothly, DONT CLEAN
IT. I know, I know......you hate for that $800 mountain bike
to sit around with a dirty chain. But, that mountain bike
is for riding, and a smooth chain is wonderful.
4) DO scrape the crud off of everything occasionally (deraillers
especially)
5)MOST IMPORTANT OF ALL: EVERY TIME YOU GO OUT, LUBRICATE
THE CHAIN. ***** EVERY TIME ***** USE A GOOD LUBRICANT
LIKE TRIFLOW. TRIFLOW WILL GRAB DIRT LIKE CRAZY, BUT YOU
WILL AVOID TIGHT LINKS IF YOU LUBRICATE ***EVERY**** TIME.
TAKE 15 SECONDS AND RUN A BEAD OF TRIFLOW ON THAT GRIMY,
UNCLEAN CHAIN_THAT_YOU_DID_NOT_CLEAN_AFTER_THE_LAST_RIDE_BECAUSE
IT_SHIFTED_SOOOOOOOO_SMOOOOOTHLY, AND IT WILL CONTINUE TO
SHIFT SOOOOOOOO SMOOOOOOTHLY. Whenever the chain goes through
water, dry it thoroughly and lubricate thoroughly. Rust
can set in overnight and cause some links to get tight.
6) Remember that tight links are also caused by poor shifts
which bend the chain side ways. Shift smoothly and dont
throw the chain (as much as possible).
Some may disagree with my methods, but after hours of aggravating
rides and testing every approach imaginable, the above method
works best for me.....Good Luck!!

927.12 | one more for Sedi chains; | AHOUSE::ACKLEY | Still the King of Nothing | Tue Nov 29 1988 17:49 | 22 |
|
I also go for the Sedisport chains. I have only had tight links
a few times. One friend tells me I should try lubing it with
dri-slide so that it attracts less dirt, although I am not having
any problem with Triflow that I am using now.
I generally run my MB chains quite dry, and lube them as little
as possible, only when the squeaks drown out causual conversations.
;^)
But once a chain is totally impregnated with dirt, it may
be necessary to toss it out if you can't get all the hidden dirt
out of it. I had to do this once after a particularly muddy
trail ride after which I had to *carry* my bike home. That
chain just didn't work right again (although I gave up on it
after only a few hours.)
It's real dry here in Colorado. Do you suppose people in
wetter areas have more chain problems? I am curious about this
since I am planning some long range tours...
Alan.

927.13 | | 28883::HOOD_DO | | Tue Dec 06 1988 09:37 | 4 |
| I think that people in wetter areas DO have more chain problems.
A chain will rust like crazy in the southeast (where humidity is
regularly 80-90% in the summer), and a wet chain will rust overnight.
|
927.14 | SIDISPORT CHAIN WORKED | USMRM5::MREID | | Thu Dec 29 1988 16:57 | 5 |
| Thanks to the advice of those who suggested switching to a Sidisport
chain, I now NEVER get tight links on the mountain bike! I don't
miss the old Uniglide and it's 5-tight-links-pre-ride performance!
