[Closed] Half link for a 9sp chain

Do you mean like a SRAM powerlink for a 9 speed chain?

or KMC call it the missing link:

No, not one of those, that would be far too simple, nice try though
It's a chain link which is wide at one end and narrow at the other, used for shortening a singlespeed chain by half a link rather than the usual whole link to get the right length. Plenty about for proper ss chains but I cant find one for a 9sp (if you have nine gears presumably you have a rear mech which acts as a tensioner so no need to bugger around with chain lengths but I want a 9sp chain on a ss bike)

I do not believe 9speed half link as such exist.

Probably the closest you get will be cannibalizing some of KMC HL1 Narrow, that is probably around 7-8speed chain width...

On the other hand why not put proper single speed chain? Any reason behind using 9 speed? Religion? Superstition? Pact with Old Ones?

Cheers!

Something like this?

I believe KMC do a 3/32" 1/2 link also

Possibly?

Can I use this with a 9 speed chain ?

Hi there,

You should be able to do this without an issue, however we have never done this so we cannot say for certain.

Thanks.

What usually happens is that my race bike gets a new 10sp chain and cassette whenever it needs one. The fun bike then gets the old one off the race bike (if that wears out first the race bike gets a new one and the fun bike gets the old one) Whenever the fun bike gets a new chain and cassette the singlespeed gets the old chain and a sprocket from it.
I therefore have a ready supply of 10sp chains for the singlspeed without ever havin to buy one just for that, and you know, reusing old stuff is just better.
This has worked for ages but now I have a new singlespeed and the tensioner has become an issue so I was trying to think of another way not not to need one and a half link seemed really cheap and easy, compared to say an EBB.
However, I was hoping to buy a single (half) link, like what stumpy suggested but a half link, rather than a whole chain, if I have to buy a new chain just for the ss I might as well get a proper ss one and have my pick of any half link I like.
I have horizontal dropouts (so no mech hanger for the tensioner I used before) and the QR rear wheel off the old bike. I would like it right up at the end of the dropout, as it is QR I can't get the skewer as tight as a bolted one so moving it back to tension the chain only works for 20-30miles then it pulls out of line. The axle is too short to use chain tugs. A new ss chain with a half link would be preferable to changing the rear wheel/hub.
I asked about 9sp as I have been using those 9sp SRAM powerlinks in 10sp chains absolutely fine and assumed 9sp was unlikely but more likely than 10sp.

The other option may be to pack something into the space between the axle and the end of the drip out to stop it moving, a sawn-off bolt or something but I dont know how well that would hold in place

I have my fair share of riding single speed with QR wheels. I can count on the fingers of my one hand when the wheel moved, even without chain tugs.

Proper QR, properly clamped and you should be fine.

Alternatively buy yourself Wipermann IG8 Pro chain and you will be set for life.

Mine is in 3rd frame now and probably pushing something around 6 or 7 years...

Cheers!

Could you use the plates from an 8 speed half link chain together with the spacer from a 9 speed chain?

What usually happens is that my race bike gets a new 10sp chain and cassette whenever it needs one. The fun bike then gets the old one off the race bike (if that wears out first the race bike gets a new one and the fun bike gets the old one) Whenever the fun bike gets a new chain and cassette the singlespeed gets the old chain and a sprocket from it.

You’ve got your priorities wrong here - singlespeeds deserve the best of everything.

The narrowest you will get is a 3/32 half link but I have found those to be problematic as they can be too wide for some 3/32 chains.
Also not sure why you are putting a worn out chain onto another bike and don't just buy a chain for £10 and leave it on there for years.

Chain arguments aside, are you using Shimano skewers? I used to use the "crappy" steel ones horsed right up and they were fine. Forget Hope skewers or whatever else, basic Shimano will do it. If you can't see the pattern on the heel of your hand after doing it up its not tight enough.

I've used these, in the past, but not since I changed to a narrow-wide chainring...
