SRAM
PC-870 6/7/8-Speed Chain

I worked on a lot of bikes this summer, including ones I refurbished to donate to kids in need. I jokingly started to say that "the chain is never good" when asked about how the work was going. For fixing shifting problems, jumping sprockets under load, and just generally getting an unrideable bike to work o.k., a replacement chain was second only to tubes for getting bikes on the road. I still need to order a couple more, and this size chain is the most commonly needed one for the multi-speed bikes I saw this year.

I use this chain on a hybrid bike that sees mostly dirt and grave. My drive train is warn out and new chain rings and cassettes are are to find. Replaced the chain to start the rebuild and it made a huge difference in shifting. Now If I could just find the other parts. I will replace this chain with a new one and have a new bike.

I purchased this chain to replace a worn out shimano chain. The bike is an older Trek mountain bike my wife rides on the trainer. The fact you need no tools to install the chain makes for a easy installation.

I used this to replace a chain with 5000+ miles, and it has been fine. Very easy to work with, but I did have to degrease it and re-lubricate it because the original grease was very thick and sticky, which is great for long term storage. But it would have attracted a lot of dirt on the roads.

Good chain, SRAM quality.

SRAM chains have always preformed well for me and I am very fond of their quick link system.

What's there to say? If you have a SRAM system you'll want a SRAM chain. We do a lot of gravel riding and having a spare chain makes it easier to keep a clean chain handy.

I have bought this chain several times before and have not had any problems. I would normally put on about 550 miles before replacing this chain.

I need to change out my chain more frequently. Now that I know how easy it is (with proper tools) I won't put it off.

Over the years I've used several of on my 8-speed and they just work and work and work until they finally wear out. I guess I've gone perhaps 20,000 miles on these chains and hope to go another 20,000.

Good replacement for that old, stretched chain. Easy to install with quick link.

After a broken chain sent me to the pavement I figured it was time for a replacement. The new chain was easy enough to install but I miss-guessed the proper length and had to remove it to remove the extra links. That was not so easy. I resorted to Youtube for help and ended up using a loop of wire to pull the pins of the master link together to unlatch the chain. I suspect that this will become easier over time.

I am using this chain on my 7-speed touring bike. It goes on easy, comes with a quick link they call a Powerlink. I tried using another brand but after just 2 years a pin had worked it's way out. I have used Sram chains on my 8 speed commuter for decades and never had any problems so went back to Sram for loaded touring.

Fits all chain rings in BMX - I usually put on a new chain if I need a longer one - never pin a chain back together unless you want to experience the pain of crashing when you break it. This is a 332 chain 6-7-8 speed width chain.

This chain seems to last longer and perform better than the 830 and 850. Looks better too.

Quiet and smooth shifting on my new old Regina 7 speed freewheel.

I bought this chain as my old one was worn out. I like the fact that the SRAM chains come with a master link, as I always use them on my bikes.

I have tried the 830, 850, and 880 chains on my year round commuter in soggy Portland, OR. I found the biggest difference showed in how long they stayed lubed, the 870 lasting the longest, the 830 the shortest. It wasn't a big jump between the 850 and 870 though. The 870 chain lasted a good long while and shifted well with a Shimano derailleur and SRAM cassette setup. Overall it did exactly what it was supposed to: propel me along.

Super replacement chain. The price is a steal for a nickle plated chain.

This chain works great, crisp and precise gear changes on the freewheels mentioned. Those old Sedisport chains are getting hard to find but, since Sachs bought Sedis and SRAM bought Sachs bicycle parts division, it has good pedigree.

I was able to swap out my old chain with this chain so easily - a perfect fit! I've already put 600 miles on the new chain without any issues.
