Good chain, no connecting pin/link

Good quality chain, but I foolishly assumed it came with a connecting pin or link - which it didn't... Don't be like me - add some connecting pins or quick links to your order!

ProsMore than long enough. Connecting link is great.
Does exactky what it says on the tin (well box). Very good chain with a few links to spare compared to the one being replaced. Obviously you need a chain tool for the initial sizing and removal of the old chain.
The inclusion of the connecting link is fantastic as it made reassembly much easier and gives you an easy removal point for future cleaning, without the need for the chain tool.

ProsEasy to put on the bike
I found this very easy to install on my bike. After removing the old chain and comparing the sizes, I found that they were almost identical in length and did not have to remove any links from the new one. It was then just a case of threading it through the gears/derailleurs and joining the two ends with the snap on link component. A low cost but good quality item which will get you mobile again easily and quickly.

Compatibility with Raleigh Record Ace
01 Mar 2021
Hello. I have a Raleigh Record Ace bought early 1980s. Rear cassette is 6 speed, gears are Shimano 600. Would this chain be compatible? If not, please could you recommend one which would be? Thank you and best regards.
Thank you for your enquiry, yes will be fine

This vs HG71?
17 Dec 2018
Is there much difference?

I am running a deore m591 9spd with a 7spd cassette on a 1987 Raleigh Royal.

Thanks SJS!
The HG71 is slightly higher quality.

Thanks - 18/12/18
Shimano CN-HG40 6 chain - can I use this with...

...the 6 speed 14-28 Shimano hyperglide freewheel?
If not, do you sell a chain that'll work with that block?
Hi there,

Yes this chain will be suitable.

Chain Confusion
04 May 2017
Back when the dinosaurs roamed the earth, there was a standard width chain because there were 5 cogs on every freewheel which went onto a 120mm OLN rear hub. There was, briefly, a narrow 6 speed freewheel which required a narrow chain but that fell by the wayside when the standard 6 speed freewheel which went onto a 126mm OLN rear hub was introduced (then, later, a 7 speed which went onto a 130mm OLN hub). My question is this. If this chain is suitable for 6 and 7 speed freewheels, why isn't it suitable for 5 speed ones. Surely the sprocket spacing is the same, the hub is just wider? By the way, I'll be using a Shimano MF-HG22 SIS 6 speed freewheel on my current build but my next project will be using an old school 5 speed Suntour CX freewheel.

This chain is compatible with a 5 speed but when Shimano bought this product out they no longer produced anything 5 speed, hence why it was not advertised.

Suitability For Ird Classica 6 Speed Freewheel
30 Dec 2015
I am looking to replace the 6 speed freewheel on my 1987 Dawes Galaxy with the IRD Classica. Will this Shimano chain be suitable to go with the new freewheel? The derailleur is the original Suntour ARll with friction shifters.
Hi, yes it will.
Will I Be Able To Remove Links With A Ct7 Chain Tool?
26 Aug 2015

Unfortunately you will not be able to use that tool with this chain or any geared chain. That chain tool is only compatible with single-speed chains and is not compatible with 3/32" (7/8Spd) or narrower chains.
