Default Octalink ES25 replacement?

How long do you guys let that go before replacing?

Can anyone recommend a better quality BB for this that lasts longer than
5k miles and doesn't cost an arm and a leg?


I see Octalink bottom brackets for sale for four British pounds :-)
http://www.chainreactioncycles.com/c...t/rp-prod34653
About $5.00.

Although I also notice that Amazon wants 20-odd dollars for one and
e-bay has them for about $18.00

I saw that as well. It's a clearance item in an odd diameter. $6.99 when
clicking the link in the US. I guess in new-speak that's called "target
group pricing" or something similar :-)

Yep. No problem to just buy one but considering the paltry service life
I would like to know whether there is something better than ES25 at
reasonable cost. Meaning not necessarily a $200+ Phil Woods BB.

I think I've got time. The current BB should hang on another 500-1000mi
until it screeches.

Mr Slocumb tried to be helpful with a rough US value.
Today's price of 4.00 Sterling alone is US$5.20:
http://www.xe.com/currencyconverter/...rom=GBP&To=USD

Plus US$1.79 delivery! Your delivered price is cheaper than
your cost of postage alone on a BB to England. Get two.

Ensure the arms are not loose on the spindle first.


They are on tight. The play is also a bit sideways. If I
keep riding will it just become gradually worse or can it
fail catastrophically in the middle of nowhere?

On my last Shimano 600 BB I rode until it had about 0.1"
play in the largest chain ring and shifting trim became iffy
(old friction shifter bike). But that was an ajustable BB
where I could milk out a second life by mounting the cranks
180 degrees rotated.

What I don't like on these newfangled BBs is the left side
plastic cup. For the road bike I got a UN-55, only aluminum
on the left but at least not plastic.


Since it's shot and since you dislike low quality bearings
and nylon
cups, Tom Kunich is right; get a better quality version
of it.


The BB-5500 Tom suggested doesn't come in the same spindle
length. Which better one could replace the ES25 and is
compatible? The ES300 looks like it also has a plastic cap
on the left.


What length? The 5500 goes to 118mm besides the regular 110mm and 113mm.


The ES25 comes in 113mm and 121mm. I haven't taken it apart yet, wanted
to do that when I know what to buy and then order immediately after
disassembly, to minimize downtime.

I've seen the ES25 advertised in 113, 118 and 126 widths.

The BB-5500 I could only find in 109.5mm and 118mm. There were also
warnings that the spindle only accommodates older 9-speed group set cranks:

https://www.excelsports.com/main.asp...or=1&minor= 6

Quote "The pipe-billet spindle has eight 9mm deep splines and only fits
older Shimano cranks - many of the 9 speed 105 (not all), Ultegra and
Dura-Ace variety". I have a Deore M522 crank set on the MTB.


I've found that there are differences in Shimano stuff that appear at
first glance to be the exact same part. I bought a 50 tooth chain
ring, after carefully checking the bolt ring diameter, for a Tiagra
crank set. The new "105" chain ring appeared in the shop to be the
same as the Tiagra (with 2 fewer teeth, of course ) but when I came to
install it I found that the outer curves of the "spokes" was not the
same and while it fitted, and worked, it looked a bit odd.

Since then I've made it a point to limit my Shimano parts buying to
buying the correct model parts :-)

Well, Chain Reaction has the ES25 BB for sterling 3.99 and the ES51
for 23.49 so you can change five ES25 BB's for the price of one ES51
:-)

I also see an ES300 for $16.68 and there are also Shimano Dura-Ace
Octalink BB's and although I don't know whether they fit, Dura-Ace is
usually considered as very high quality.

That is weird, never seen that here in the US. Maybe there is a Thai
model and a US model :-)

I never cared about the aesthetics of my bikes. As long as it could be
made to fit and work with acceptable reliability it was ok. Which has
also meant using non-bicycle parts on bicycles because those are almost
by default more reliable.

The UN-55 is the Canine Wobblers of BBs imho. Cottered, Octalink,
Outboard, have all failed me over the years, but never a UN-55. Ok,
they do eventually wear out with year long commuting, but I reckon on
10-15k miles. That said, the last was on the 10K side of things. Bit
disappointed tbh, but the Shimano outboard ones I used to change
annually and I had stability issues with the Octalink. That said, I
still do have one Octalink, and it seems ok and 3k miles, but them's is
dry miles...

However, 73mm won't fit which is all they've got and then I'd only have
two paper weights.

But yes, if I can't find anything better than ES25 or ES300 I'll get two
and consider them yet another fast-wear items, along with tires, chains,
cassettes and brake pads.

http://www.ebay.com/itm/Shimano-BB-5....c100506.m3226

Cost three times what the ES25 does and I've never had one fail.


$40 is perfectly ok. Unfortunately their available spindle lengths do
not fit the ES25. ES300 has very close to the same spindle lengths, I
just don't know whether they are any better than ES25.


I believe that the widest available in the ES-25 is 121. The 5500 is available in a 118 and it's my guess that it would fit right on.

I meant different prices for different regions or people. One big player
recently got into trouble for that which netted them a not-so-honorary
mention in the Wall Street Journal.

Then there is dynamic pricing where if you click too often on an item
its price suddenly ratchets up. I immediately head to a competitor if
any store does that to me.

I don't care if it's $10, $20 or $30. As long as it fits and I don't
have to change those things like underwear.

Octalink BB's and although I don't know whether they fit, Dura-Ace is

It may be time to write to Shimano, hoping they'll answer. To me this
flurry of model numbers is confusing and not all are 100% compatible.
The cranks have to fit and the chain line should remain roughly the same.

I was hoping that someone had the same issue with paltry ES25 lifetime
and could tell me "Here, buy that one, lasts a lot longer" (and where it
fits well).
