This chain works well on my bike..

Since I have other bikes, I logged less than 500 miles on this chain.

This chain is pretty good for a 6-7 speed freewheel or cassette.

The KMC Z50 is a fair-quality, 7.3mm wide chain for use on bikes that use six- or seven-sprocket cassettes or freewheels. According to the KMC specifications, the Z50 chain is too wide to work on eight sprockets or more. Also this chain has 116 links which should be long enough for most chainstay lengths and front\rear sprocket combinations on older bikes.

This is not a premium chain, but I don't believe KMC or SRAM make any other 7.3mm wide, 116 link chains for six or seven sprockets. (I am not familiar with the possible Shimano options for this, and their website is not helpful.)

So if you are doing hard riding with many shifts under load, you should check this Z50 chain after a while for stretch, to avoid sprocket and chainring wear. But since this chain is inexpensive, you can obviously buy spares to have on hand.

There are 7.1mm width chains by KMC and SRAM (designed for seven or eight sprockets) that may be be better quality, and these may also work on six sprockets. However, some of these narrower chains have 114 links or less. They may be an inch (2 links) too short for the 116 link chain length needed for a touring bike or old mountain bike with a long chainstay length (greater than 17.5") and a large top chainring and rear sprocket. To check this, you can count the number of links on your current chain. Or use one of the on-line bike chain length calculators that will tell you the needed chain length based on your chainstay length and the size of your largest front chainring and rear sproket.

Unlike the SRAM chains, the Z50 does not come with a master link. You should buy the correct size KMC brand "Missing Link" (master link) for a 7.3mm chain width. These links come in different widths for the various KMC chain widths.

I've used these chains for recumbent construction for 18 months now and they hold up well. There is 12 feet of chain on my TriCruiser recumbents and strength with affordability is very important.

Years ago I had a gold colored Shimano chain that seemed to spin with smoother and with a bit less resistance, but this chain is very affordable, $10 to $20 dollars. It works like a charm, shifts perfectly, and holds up well. I have had my chain a few years, do most of my riding on a Blackburn trackstand and then do a 15 or 20 mile ride on the weekends.The Z chain is like a Toyota, reliable as the day is long.

Prefer KMC to Shimano for the quick link but then I also use the quick links on Shimano chains. Both work great.

This was a perfect replacement for my 1984 Trek 720 that I was restoring. It runs smooth and shifts easy.

This chain is quiet on an old Trek 820 mountain bike with original Shimano drive train components and Grip Shift 21-speed. It shifts very nicely.
