Shimano chain life

[Neal]

My latest bike has a Shimano Ultegra 10speed drive train. I only have 1200
miles on it and already the chain is measuring close to the replacement
point. I'm used to Campagnolo equipment and I have gotten 4000 miles on
Campy chains. Is this typical chain life for Shimano? I lube the chain
every 100 miles with Prolink. I also checked another Shimano equiped bike
with only 1100 miles on the chain and it is showing considerable wear too.
Is the Dura Ace chain more durable?

Question, was your "Campagnolo equipment" made for 10 speed
drivetrain? I think the issue is not so much Shimano versus Campy
versus others, but probably more that the 10s chains are so narrow/
thin that it is possible to *wear* them out in about 1000 miles or
so.

I wouldn't spend the $$ on a DA chain. Instead, find the cheapest
chains and replace when needed. One of the problems with 10s is that
consumables like chains and cassettes are very expensive. Unless
you're racing and *NEED* to count every gram, use the cheapest and
replace often. Good Luck!

Use a Campy chain if you prefer. For my wallet, I'd give a $30 KMC a
shot.

How did you check the chain wear? A Rohloff caliber gives a pessimistic
chainwear with a Shimano 10 speed chain.

I've gotten WAY more than 1200 miles on Ultegra 6600 chains. In grimy
conditions using all different types of lube, and quite often hardly
any at all when it gets rinsed off.

I also broke a near new 6600 chain recently, so who knows.

Yes, the Campagnol setup is Chorus 10 speed. I actually got 4800 miles on
my last Campy chain. The Shimano chain is not much narrower than the 9 speed
chain. The Campy chains are narrower. The difference in price between an
Ultegra chain and the Dura Ace is only $5. ($21 vs $26) so if it lasts
longer it might be a better deal.

I first measured with a ruler to 12 inches and then tried a Park gauge.
Both methods indicated wear.

Hmm. The last chain on my singlespeed was a (9 speed) Shimano chain and
it wore out extremely fast. Much faster then the SRAM chains I used in
the past. On my road bikes I get very good mileage (10000 km) with
Campagnolo 10 speed chains with a good clean and lube regime.

I go through chains like butter (I weigh too much, I only ride in the hills,
and my drivetrain gets mucky and stays mucky due to rides in
less-than-perfect weather sometimes), but even so I get closer to 2k miles
on a Shimano 10-speed chain. If you're just dumping Prolink on the chain
instead of actually keeping it clean, that could be part of the problem.

People who get 10k miles on a chain... I don't know how they do it. Unless
they weigh very little, only ride the flats, and spend more time cleaning
their bike than riding it. The other variable is how often they like to
replace the rear cogs. At 2k/chain, I get 5 chains to 1 cassette. I'm sure I
could get more miles out of the chain at the expense of cassette life, but I
also value the better shifting you get with a drivetrain that's in better
shape.

Mike, what is the soil type or types your route rides on? Is there
digging or construction locally for spreading grit on the road
surface? You ride in the desert? windblown sand?

I'm using a KMC - Z610HX singlespeed/BMX chain and a singlespeed sprocket
now. I was attrackted to the anti drop feature of this chain. We will see
how it wears.

I got 4500 miles until 1/8th over an 11" span (my ruler is only 12"
long) from a 9 speed SRAM chain cleaned probably about 10 times during
its life.

I checked the wear when I cleaned it and sometimes made a note of it.
2900 miles into its life wear was only 1/32". That was in September, at
the start of the muddy season. There were probably a disproportionate
number of cleanings over those last 1600 miles between September and
March because of the mud, but that's still when 3/4 of the total wear
occurred.

I used a drip-on lube similar to FL Teflon.

Conclusion: mud, sand, grime kills chains. Cleaning them makes little or
no difference. I still do but only because I like that clean chain
feeling.

4500 miles from a Spam chain. wierd. No sooner, whispering "chain",

We sell the park tool(CC-3) and use the Rohloff and the park is more
pessimistic than the Rohloff. The Park 'gauge' type, CC-2 is a poor
tool.

I get a good 2K out of the cheapest KMC "bmx" chains with single
speeds. I could probably do 3, but after 2 it's time to change colors.
Ten bucks a pop and strong! Also sold as *mart and Diamondback brands.
Like I mentioned in another post, the last one was chrome and $8 from
"Dick's Sporting Goods" in a strip mall, as my LBS only stocks more
expensive and much noisier Sram stoff.

From my postiing to r.b.t on April 23, 1997 (thanks Google Groups):

"As promised, I cleaned and waxed my road bike chains yesterday
afternoon. I decided it was finally time to replace my high mileage
Dura-Ace chain because it had 3/32" of "stretch" over two feet, but I
though I'd run it until it needed waxing again. So I put it back on
the bike and headed for last evening's club ride. On the ride I was
telling the group that I'd finally decided to replace my high mileage
chain, and we got into a discussion of chain cleaning, lubrication,
and life expectancy. Within a couple of miles, while I was
downshifting the front derailleur, the chain came apart. It looks like
one of the pins pulled out. So after 18,138.6 miles of repeatedly
pushing pins in and out, one of them failed. Guess I should have been
using those black pins all along ;-).

"When I finally reached the parking lot at the end of the ride with a
chain now one inch shorter, I was (of course) greeted with hoots of
dirision and a chorus of "Workin' on a Chain Gang". So My Dura-Ace
chain (at least most of the links) made it to 18,142.4 miles."

info. shimano 9s chains are 6.5mm.




Some websites state the Shimano 10 chains are 5.88mm wide and others say the
chain is 6.1mm. What is meant by width? Is it measuring the lenght of the
pins or the side plates? I have also read that the Wipperman 5.9 mm
connecting link does not work on Shimano chains because it is too narrow. Is
this correct?

Yep, you guessed it. I've set up a velodrome inside a working quarry.
Couldn't afford to pave it so a lot of dirt gets picked up as I ride, plus
all the dust from the quarry operations. It hasn't rained in 12 years, so we
he don't have enough water and have to clean things by sand-blasting. Guess
chains don't like that.

Sheldon missed that one: a soil types - chain wear chart
Chain wear here is down 300% with no construction in an old
nayborhood on coarse sand after riding thru construction digging up
new sharper sand.
Wonder who knows? drilling ? earth moving ? Ford ?
What's worse? granite dust or sand.
One thing, high mileage claims were not sprung from wet riding.
