Add octalink bb to 90s road bike

[zarfus1@gmail.com]

I have an old fuji, and its time to replace the crank ( the chainrings
are worn, and not replacable). It currently uses a square taper
bottom bracket.

I want a 53t, and i found a nice crankset online, but it is compatible
with an octalink style bottom bracket. I am due for a rebuild of the
bb anyways, so I was thinking of replacing the loose ball bb with a
cartridge octalink.

Is this a good/bad idea? Is it hard to figure exactly which octalink
bb to buy, or any will work if it has the right width?

Thanks,

Dan

Octalink has 2 versions: V1 was mostly for road cranks. I believe the
only BBs still available in that version are the Dura-Ace 7700 and 105
5500. V2 was mostly mountain bike cranks, although the Tiagra and Sora
octalink cranks used V2 as well. These are the ES-series BBs.

FWIW, Shimano already considers these to be obsolete, and is moving to
outboard BBs on most models. Lower-end stuff is still square-taper.

I'm not a fan of pipe billet splined BBs (Bearings are too small), but
many people like them. If the crank is a good deal, maybe it's not a
bad idea.

FWIW, if it were me, I'd either stick with square taper or switch to
outboard.

That's a religious question.

Do you prefer nice smiling Buddhists or crazed hostage-beheading
moslems? Either could possibly work out.

Since it's a Fuji it almost certainly has an English-threaded bottom
bracket shell in a 68mm width. So an Octalink bottom bracket for such a
shell should thread right in, no problem.

Shimano's Octalink bottom brackets only come in a few widths, to work
with their Octalink cranks. If you're putting on a double Octalink road
crank, you'd want a 68x109.5mm English Octalink bottom bracket. Be
warned that Shimano has two versions of Octalink, V1 which is the
105/Ultegra/Dura-Ace design and V2, which is /not/ compatible with V1,
that is used on some mountain groups and the newer Tiagra and Sora
groups. Don't try to use a Tiagra or Sora Octalink bottom bracket with a
105/Ultegra/Dura-Ace Octalink crank or vice versa.

On the other hand, you could if you wanted to use a Tiagra or Sora crank
and matching bottom bracket. But considering that Nashbar frequently has
the Octalink V1 road cranks on sale for big discounts (trying to move
their 9-speed stock, I'm guessing) you'd probably pay less for an
Ultegra crank.

As usual, the late Sheldon Brown has the goods on Shimano bracket types:

I'm not a bike shop owner or employee, nor do I pretend to be one on
the wwweb. However, I heard, and had no problem believing, that
Octalink is obsolink, and is not being "supported"; further, that what
was left over from old production was getting scarce.

So I googled and picked the first likely source, just to have some
reference-don't-blame-Lickton's of what is going on:

N'octalink seems to be the coming thing. And it's a Fuji. Hmmm...
some kind of nice square-taper (Superbe?) NOS crank, that at least you
could buy a Phil BB for (ever), scarce as the Grease Guard items are?
I believe those fine Japanese cranks were made in 144bcd (tracl and
road) as well as 130bcd (?) --D-y

I ride a cheap asian improt, '87 ?
Replaced one new Shimano ball and cone with a cheap shimano Octa and
a cheap Shimano 105 touring Crankset ($39?).
I YAM ARMSTRONG. spinnerrrooooo!
perfect circles everytime.
then go for a Specialized saddle and side pull brakes mounted on Al
adapter plates.
then you can spin and stop.

What group is the equivalent of an Ashtabula crank?

Above information is pretty complete, I'd go with it. About a year ago I saw
new Ultegra V1 109.5 English going for $39, its a solid sealed unit. The DA7700
octalink will need more maintenance, the bearings are on races that come out.
And its more suceptible to water.

Oh, wait... that's not a religion. Nevermind!
