[Closed] Shimano - 'do not rejoin a chain at a connecting pin'.. why ?

youve got it !

the shape of the joining pin stretches the hole.

just use the link next to it and rejoin with a new joining pin - or even better , remove the link with the joining pin and use a power link for rejoining !

cool, Ta

I recall that was the gist of it. Popping out a pin enlarges the hole, you use a bigger pin to fill the hole, but don't pop that bigger one once installed. This is all a bit hazy because as soon as Shimano started along this stupid path I started using Sram chains with powerlinks..... 😉

joining pin is (I think) a bit softer and a tiny bit bigger than standard ones. Intended for singles use.

Get a powerlink, thur gud

Bah, too slow! 😆

Better still, get a Connex powerlink. Much better design than the SRAM ones.

So, at the risk of being a numpty, if I regularly split and rejoin my chain with an old fashioned chain tool, pushing out whatever pin happens to be in the most convenient place, will I knacker it and die horribly? Am I even more stupid than I thought I was? Is my rejection of all things modern like powerlinks going to result in a snapped chain and broken goolies?

lol @ mrbelowski 😆

according to Shimano, probably.....I have just ordered some KMC joining links (10 sp for road Ultegra)

Aw man, don't just laugh at me because I'm thick, answer the question 🙂

this is what we all did before the power link - there were connectors but they were gash IMHO

IME if you have weakened it it will break the first ride up a big hill as you put down the power
Best to avoid dooing this as there are better more modern solutions but I have done it recently with a chain when i fitted an SRAM powerlink and it wont undo [KMC chain IIRC] as it is not suitable and i needed to shorten the chain
I have not died yet and it has not broken ...yet
HTH

mrbelowski - I asked the question too ! 'cos I don't want the breaking scenario, balls into stem situation... I think £6 is money well spent

If it's stiff try a tiny amount of extra turn on the rear rack of your chain tool. Never had to do it before on a connecting pin though.

Can I also add I like the connecting pin. Easy to fit. No faff and i hardly ever remove a chain mid use.

IIRC 10 speed quick links are not reusable either?

I've been joining chains with old pins for the last 25 years and never had a problem caused by it

I used to use old pins (push pin 2/3 out, remove dodgy link, rejoin using '2/3 pushed' pin to locate etc.) with not too many problems, except when I was being a bit cack-handed or doing it with an old chain or something.

+1 for connecting pins though, smooth and lovely. But I don't remove my chain unless its to replace it or because its already broken..

[i]IIRC 10 speed quick links are not reusable either? [/i]

I think it depends on the brand, but don't quote me 😕

I think the chains we all used to just reuse pins the pins were parallel sided. Modern shimano chains are not - the pins are slightly wider at the end so when you push the pin out it damages both the pin and the plate - so rejoining with that pin will be weaker.

SRAM links FTW

[s]SRAM[/s] Connex links FTW

FTFY 🙂

Do the SRAM powerlinks work ok with Shimano chains?

mark - the 9 speed SRAM Powerlinks work perfectly with Shimano 9 speed chains - been using on mtb's for years. This time I am on 10 speed road bike, and the SRAM one is not reuaseable - it's called a Powerlock

Rejoining using the old pin worked OK for wider chains (i.e. less than 9 speed).

I can tell you from mildly painful experience that it does not work OK on 9 speed. It also won't necessarily go on the first hill you encounter. Mine went on the top of High Street, two or three rides after I split and rejoined it.

@iainc: the 10 speed powerlock is reusable if you have some of these: [url] http://www.chainreactioncycles.com/Models.aspx?ModelID=46600 [/url]

I found that rejoining Shimano chains using an old pin works fine on the cheaper chains such as Deore. Trying it on an XT chain caused me pain

[i]Do the SRAM powerlinks work ok with Shimano chains?[/i]

In my experience of 9spd Shimano/Tacx/SRAM/Connex/possibly other brands of chains and powerlinks, they're all inter-compatible.

But Connex ones are the best.

I would echo the above. I once tried joining a 9 speed chain in my ignorance got to Thetford, parked up got on the bike and did not even get out of the carpark before it snapped. Started using missing links from that day on.

Arrrggghhh you buggers have just cost me £20. Or saved me an injury

£20. Grrrrrr

£20 - is that for a few spares too ? I ordered the KMC ones at Ribble at £6 for 2

[url= http://singletrackworld.com/forum/topic/what-10-speed-powerlock-for-ultegra-road-chain ]on this thread[/url]

It'll be more than £20 by the time I've replaced by worn cassette 🙁

Saving me personal injury and encouraging the replacement of worn out bits is simply not on

Decathlon (I know!) do own brand 10spd powerlinks that i can't tell any different to the Connex ones, but they are £5 for 2 pairs (ie enough to join a chain and then have another as spare)

I get 2pac sram power links from there for a similar price.

"IME if you have weakened it it will break [s]the first ride up a big hill[/s] at a random time of its choosing as you put down the power"

Redirecting aforementioned power through some part of the bike and into your nuts.

iainc/IHN - thanks for the confirmation about the compatibility. I'm running Shimano 9 spd so will be investing in a couple of powerlinks.
