Question: Is the correct part # CL573R or a CL571R (KMC MissingLink) being sold here...as commented by Qbee (I think he received the CL571R by mistake, and couldn't use it.) The photo shows it as part # CL573R, so I'm confused by the comment that Qbee left. (His information is correct and is helpful by pointing this out.) Please let us all know so we can order the correct part the FIRST TIME. Thanks for your help in this matter.
Document: This is CL571R for IG chain(7.1mm pin length)My chain is HG chain(7.3mm pin length).so I could not use this link.X(If you have HG chain you need to buy CL573R.
Very very happy with this purchase. I have been doing bicycle repairs for over 20 years, mostlytires,brakes,  and adjustments, but had no experience repairing a chain. I was fairly certain that I would needto head to the bike shop, or that I would need to replace the chain to get rolling again.....but the Missing Linksaved the day. Make sure you order the correct link for your bike and you are all set.I did not use any tools to install mine.
My KMC Z51 came with one of these, I didn't know that so I bought a pack. These are dead easy to install: insert both halves into their corresponding links, assemble them, and pull the chain ends in opposite directions, the missing link halves will &#34;click&#34; into place, and you're done. No tools, no wrenches or pliers needed, nothing. Just awesome.
So now I have five links and that is a good thing.Used for Z51 RB Touring - Index KMC Chain fits - works perfectly. I MTB coastal trailsZero problems -  zero rustChain and link used as direct replacement for  29&#34; Northrock 24 speed sold by Costco
A quality product, allows me to more easily remove the 80&#34;s Sedisport chains I use on my higher end bikes.
These things are great. Easy to install and remove. I buy Shimano chain but they're too long and their master links aren't worth much. Use these after removing links to get the length I need. And if I didn't get it right the first time, it's easy to remove and take out a few more links.
I usually buy SRAM PowerLinks, but find them hard to remove when I need. So I gave these from KMC a try. It works! Pinch it together and it can be removed and reused if necessary. And so far it hasn't come off when I didn't want it to.
The nicest things I like about them are:1) No tools required to install (you will still need a small chain tool, such as the Park Tool Mini Chain Brute Chain Tool - CT-5 to remove the broken link from your broken chain)2) They are re-usable. Once you do a more permanent repair, you can save it to use again, in the event of another unfortunate chain breakage.I highly recommend these for any bicyclist!
I have SRAM chains on all my road bikes.The older 8spd took the p870 and the quick link SRAM offers (and is the 7/8 spd version of the 10spd SRAM chain on my CF)is a bear to remove.This KMC Missing link installed and removed easily and held when fastened.Color me impressed and satisfied.Now,if only they made the same deal for the 10spd chains...
These KMC missing links make installation or repair of a bike chain as easy as pie! They go on by hand with no special tools and only require a stiff tug to add tension to the chain for them to "snap" into place. Quite possibly the easiest thing I have ever done on a bike!The package comes with perforations around each set of missing links so it is easy to just open one without all the others being loose.
