Hi,

What can I do about this.It protrudes out about 2mm from the rest of the pins and hits the front Derailleur.I read that it's a protective chain link due to a repair job.Is this true? Is it possible to get it flush like all the others

saintx

try pushing it back in

msheron

Exactamundo...............use a chain tool however!

brundle_fly

Oh....Is it that simple.That's nice to hear.Many thanks

There is more than one possibilty. You don't give any information. Is it a nine speed cassette?

Some replacement pins have to be installed and have part of the pin snapped off. If this was not the case and the other side was 2mm away from where it goes into the side plate it may break the chain. If you are not exactly sure what is going on take it to a good shop. If you are riding and that gets hung up on something you could have a big problem. It has happened.

2mm is about the thickness of the chain side plate which means if it is sticking out on one side this amount the chain would have come apart. If it is a shimano chain the connecter pins are tappered and broken off at the score marks. Its possible that a 9spd pin was used on a 10 spd chain. with shimano you can't remove a replacement pin and reinstall another because of the slight enlargement of the side plate hole. your best bet is to remove that link and replace it with a new link or get a master link like a wipperman connex and make sure it the right size(width)for your chain. shimano 10spd is like 6.2 mm

It's Shimano 10spd and the Chain is Ultegra and Cassette 10spd.
I have found out in the manual that it is called a reinforced pinApparently it comes with the with the chain and can't be changed? Surely it can't be right if it is sticking out though and hitting the Derailleur.

Just got this from another thread

[QUOTE]edmaverik
I've been riding w/ DA10 for the last 7 months and personally, I believe their chain can last 1,500+ miles. What I think really sucks is the crappy DA10 chain connecting pin. They are a garbage. I'd say save your frustrations and buy a Whipperman 10-spd stainless steel chain or a KMC 10-spd chain that have a "link like connection" instead of the crappy "Shimana so-called reinforced chain pin connector. They fail and start disconnecting from the chains.

I could not be happier now w/ a Shimano 10-spd chain and a KMC 10-spd "missing link" solution, its fool proof.[/QUOTE]

Do not put it back in!!!!

Replace it with a new pin. If you put it back in, it's like using used pin again which might fail and come out on a middle of ride.

There is nothing wrong with the DA chain connecting pin, but if you install it incorrectly or reuse the pin, you might have a problem or two.

I use a Wipperman 10 SO and it is a great chain. Performance Bike had them on clearance at a decent price.

I don't know about that. Their CN-7801, CN-6600, and CN-5600 use a different chain pin than the original pin used in the CN-7800. I think they changed the design because there was probably something problematic with the pins used in the CN-7800. Shimano indicates it's more user/mechanic friendly, but I suspect that it has something to do with the design of the original 10sp connecting pins.

Thanks for the replies but haven't really got any straight answers yet
IS THE REINFORCED PIN SUPPOSED TO BE STICKING OUT OF THE CHAIN

Crayon

NO, it not. Take the damn thing to a shop and get it fixed.

Riding like that is extremely dangerous. Ever see what happens when a chain breaks? Automatic sex change operation. One of the worst possible bike component failures.

+1. Having just had a chain failure on my Ultegra 10 drivetrain that cost me a chain, cassette, rear derailleur, derailleur hanger, and some work bending my chainring teeth back into place, I can tell you it's not worth it to keep riding that chain. No, nothing is supposed to protrude from the chain. Pop the whole pin out and replace it with a 10-speed HG pin (make SURE it's a 10-speed pin, they're different) or take it to your shop.

linus

So....I know what you think, but where is the fact?

brundle_fly

I took it to my LBS in the end.He said there was nothing wrong with it.
Apparently the racing standards chains (Ultegra and D/A) come with this extra strengthening pin,as opposed to my previous Tiagra chain which I actually prefered.
Nevermind,I'll just have to adjust the front Derailleur out slightly to accomodate for it

ranger5oh

I havent read all the posts... but make sure you get this fixed! This happened to me, and ended up destroying my rear derailieur and denting my frame! Luckily, it wasnt my fault and was actually the LBS's fault, but it can really cause a LOT of damage!

onRoffR

In your OP you stated that the pin stuck out 2mm. That is a lot! and not ok. You said you have the chain manual. It has a rightway/wrong way diagram at the bottom and the pin extruding from the side plate has a universal wrong way icon by it. The manual also states that you cannot break the chain at a replacement connecting pin spot as this damages the chain, as I previously stated the connecting pin enlarges the side plate hole and uses the friction of the pin taper to hold in place if you push this thru to remove it enlarges the hole more and the new pin will hold but not to manufacturer specs and can fail at any time. If your LBS installed this chain I would insist that it be done right even if they have to replace a link or two, or give you a master link like a connex link IRC also makes a shimano 10sp link as well. Its like playing russian roulette with your drive train leaving the pin extruding. at some point the pin will hit a derailuer at a critical shift point, or the chain could break while riding

brundle_fly

Thanks onRoffR.Excuse my ignorance but the connecting pin you are talking about is the one which looks different from the others? Haven't come across any wrong/right way diagram.My LBS actually pushed the link in now both sides are about 1mm sticking out each side,and this pin is longer than the others.My LBS has been buying selling race bikes for over 20 years and he says it's ok.I still don't know if this Ultegra chain is supposed to be like this?

That is just plain wrong and dangerous. There should be nothing sticking out, period! 10 speed DA chains do use longer reinforced pins. I would replace that pin all together.

When replacing 10 speed D/A pin, use a chain tool to push the old pin out. The old pin does not fall off the chain once pushed out though. The new pin will push the old pin out for you. The new pin should sit flush with the link. Then just use the chain tool to snap off the other side of the pin. It should break cleanly and also sit flush with the chain. Just make sure you get the right pin!

onRoffR

The shimano replacement pin is not longer than the factory pin. If it is the correct pin. the 10 sp pin breaks off flush. the pin has a breakaway section when snapped it should be flush. period! the pin looks a little longer only because it is flush and not dimpled on the ends like the factory assembly pins. it still should be flush smooth to touch if you run you finger along the side of the chain.It sounds to me like the wrong size pin was used. Shops usally have bins of these pins they buy them in bulk and the mechanic may have grabbed the wrong one. I'm sure if you Emailed shimano customer service they could contact the shop about the safety standards for their products.

Willks

Here is a good read from the park tool website on how to replace pins.

Also, if you "break" your chain allot to clean it, I suggest you get a KMC link or something similar. I attached a picture of a 10spd D/A pin and my KMC link installed on my 10spd D/A chain.

brundle_fly

dwilkinsjr,

Have you done away with the reinforced pin altogether,even though Shimano say not to change it?
Is that a standard D/A pin you have in that link.
