Subject: Urgent! Can a Vitus 1980's frame B spread to 130mm?
|
Hi there. I have a chance to get a Vitus frame circa 1980s that will
fit me to a T. I really would like to get it.
I would like to put a 9 speed Campy drivetrain on it. Can the rear
triangle of that frame *SAFELY* be spread to 130 mm?
Time is short so I need to know asap if thtat can be done.
Did these Vitus frames use 27.2 mm seatposts and a standard size quill
stem?
Is it suitable for 180 lbs rider?
Thanks from Peter

Oh, and in one of the OP's other threads, he linked to some pics of
the frame. It's a classic 979 frame, in a lovely shade of blue.

All the Vitus-branded ones were either Al, or CF with Al lugs. Yes,
they made steel tubing, but they did not market frames made of it.
They sold tubesets to Peugeot et al, who made & marketed them.
And 99.9% of the time when someone says "Vitus Frame" they mean the
classic 979 Aluminum Frame. To exhort against the assumption, just
because those other options options exist, is just silly, IMHO.

Were all '80s Vitus frames Al lugged? None were steel? Or did I miss
where the OP said that it was an Al or CF frame?

Hi:
I am not ain engineer, so I will probably use the wrong language to
explain this. But here it goes. Steel can be bend back and forth
several times. sort of like a paper clip. You unfold it, clean your
teeth with one end, fold it back and use it to hold a few sheets of
papers together. The next day after lunch, you take the same paper
clip, you unfold it, pick you teeth, and then fold it back. later that
afternoon, your back itches, and you can't reach. You unfold the paper
clip scratch your back and fold it again.
You can do this with a paper clip many times, before the material
fatigues and it snaps. Paper clips are made of steel.
Now, imagine that you wanted to save some weight in your breifcase.
So, you buy aluminum paper clips. The have been tested to resist the
minor stress of holding a few sheets together. The moment that you
open it t clean your teeth, it snaps. If you put a stack of sheets to
thick, it snaps.
So, to answer your question, a steel frame is like a regular paper
clip. You can bend it w/o much problem and can bend it back and forth
several times. An aluminum frame is like an aluminum paper clip would
be. You can bend it a little, it may snap.
Also, steel and aluminum snap differently. If you bend a paper clip
back and forth many times, you will see that the material starts
getting weaker slowly and you can pretty much predict when it is about
to break. With aluminum, you will not be able to predict anything. It
will snap suddenly.
The vitus frame has two points where it can fail. At the bottom
bracket they are glued to a lug with superglue. The stress from
bending its stays out may cause the frame to fail there. It can come
unglued at the bottom bracket. Also, the dropouts are parallel to each
other. When you spread the stays, the dropouts cease to be paralel and
you need to bend them in a little to make them parallel to each other.
You can do this before you put 130 mm axle. This is called cold
setting. and the frame may snap when you do this. You can do it every
time when you install your wheel and it can snap anytime while riding.
If you don't cold set a frame, you will be riding it under constant
tension from the quick release pressing against the dropouts while the
hub axle forces the seatstays to spread.
Knowing this, there is a great advantage to riding this frame. Every
time your get on the bike, your heart rate will already be 20 beats
per minute faster with fear. Your workouts will certainly be more
efficient. That's until your break your collar bone and you spend
three months off the bike.
So, do as you wish, but my advise as I said a few weeks ago is to wait
for an 80s chromoly frame, such as a centurion, nishiki, trek,
specialized to come along. There are many that you can get for less
than $100. that are great. Otherwise, get a brand new aluminum frame
for $120.00 or less. Leader is one way to go.

Another point to watch out for, when the dropouts are not parallel they
put a lot of stress on the axle.

Hi there. My ride to see the frame has had an emergency crop up and
can not take me to see the frame. This means I will not be getting it.
Thanks all for the advice and warnings.

As many have said, spreading this frame would be a Really Bad IdeaTM.
But there are a few options: you could get some 8-speed ergos: Campy 8-
speed spacing was the same as Shimano 7-speed. Throw a 7-speed
freewheel (like the new IRD ones) on some vintage wheels, and you're
set.
Another option would be to find a 7-speed Hyperglide hub, and put 8
cogs of a 9-speed cassette on it. You'll have your 9-speed spacing,
and Shimano 9 is close enough to Campy 9 to work fine.

Used a 130mm clincher rear wheel for a while, 8 of 8, after removing spacers
and carefully adjusting the hub position and the axle.
Now running Dura Ace 7 of 8 speed on a DA 6 speed uniglide rear (tubular),
which was original to this 1985 Vitus Carbon 3 frame.
The aluminum dropouts are wide, extra thick where the hub rests. If anyone
were bold enough to remove material from the inside face of the dropouts a
130mm wheel might fit. I would not do that, or spread the rear. Better to
make the wheel fit the frame.
The seat post uses a quill stem on my ride, which used to make it a pain to
adjust up and down.

Hi Andrew and thanks.
This Vitus is just the frame, bb and headset and fork. The seller said
he had an 8 speed 130 mm setup without proble. He also says there are
a few nicks from normal wear and tear.
Is there any way to tell just by looking at the frame if he damaged
the integrity of the frame by spreading it to 130 mm?
Thanks again from Peter

I would never buy a second hand (lugged) aluminum Vitus frame from the
80's.

When you force the dropouts off parallel, with a 130mm wheel, and then
force them parallel with a skewer, you run the risk of breaking the
glued joint of the dropout to the seatstay.

Which tubeset? where had both doublebouted steel, plain gaauge steel
and a aluminum frame. The later is by far the most known since S.Kelly
used it for most of his carriere.

The steel versions had 126mm, it should be ok to spread them,
regarding the alluminim frames i wouldn't do it.

no 27,2mm, standart 1" quill, mabye an odd french messurement for the
bottom bracket.

Maybe.
US, British or some Belgian builders using Imperial dimensioned Vitus
steel tube would have a 27.2 post, assuming Vitus premium (971) steel
tube with a single butted seat tube. Double butted seat tubes 26.8.
Smaller for less than premium tube (888, 172 series).
If the builder was French or Belgian, using metric tube, the seat post
would be 26.8 for premium tubing. Smaller seat post with a double butted
seat tube or lesser material.
But then the bike would bear the builder's name, not "Vitus".
OP most probably meant a Vitus-Bador model 979 aluminum frame. Or
possibly a Vitus Futural or maybe a Vitus Carbon 3 or Carbon 7. That
frame system takes a 25.0 seat post. Both BSC and Metric versions were
produced so we can't know if his BB, headset and stem are metric or BSC.
I agree that a 120mm or 125mm steel bike should have no issues moving to
a modern 130mm. A cast aluminum BB with glued in aluminum stays and
bridges is another story. Trouble all around. I wouldn't do it.

On the topic of bending a frame in the other direction to make a
fixie, having been thoroughly sold by this newsgroup...
I'm putting a 120mm Surly track hub on a late 70's Swiss-made 126mm
Oschner. The seatpost is 26.6 and there is no tubing label. I recall
it was the cheaper of 2 Oschner frame models when I bought it new 25
yrs ago for about $150. The only decals are 2 OSCHNER labels, and
another with what looks like Oschners signature. No model name or
other clues, but for a serial # stamped under the BB. So I'm assuming
it's cheap tubing, or as cheap as Oschner would go, but I imagine for
purposes of bending to 120, all that matters is that it's a steel
alloy, which I suppose it is
So, am I better off having the LBS make the frame 120mm, if that's
possible, or just simply spacing out the 120mm hub with hub axle
spacers.
Sorry for OT, but thanks in advance!

Columbus Zeta tube. Frame's well built (Swiss), tough and not risky to
retrack.
N.B. - only a small effort is needed to make a rear end narrower. Link
your fingers together and press your palms on the ends. Easy does it! A
frame alignment shop will ensure the ends are parallel with Campagnolo
"H" tools.

Ask the LBS which they would rather do. For my part, I would tend to
respace the hub in this case, rather than the frame. The only reason to
do the frame is if you contemplate routinely using other track wheels in
it.
The main reason for respacing is to use newer, gearier drivetrains,
where the spacing is the minimum possible for those drivetrains, more or
less.
Well that, and because 130 mm is pretty much a universal road standard
so you can use virtually any wheel at that point.

Good arguments for spacers. I'm sure there won't be multiple fixie
wheels. Other comments in the thread about misaligned dropouts and
bending forces on the axle are unappealing.
Not to mention that I just recalled that I have on order a 137mm QR
axle replacement, which only works with 126mm dropout spacing.
thanks for the comments.

Seatpost of a Vitus 979 is 25.0mm
Both BSC and metric (French!) dimension Vitus 979 frames were built.
Stem could be 22.0mm with a metric fork...
I wouldn't change one to 130mm unless the owner clearly understood that
it could well be fatal to the frame. Not recommended.
Can't you find a steel frame? Post-1995 Reynolds 853 or True Temper OX
TIG frames weigh the same or less than a Vitus 979. Or ride vintage
wheels maybe?
