I recently replaced a broken chain on my mtn. bike converted commuter with the PC-870 chain... its works great! Durable (so far), quick shifts and quiet. Easy to install with the master link and with Western Bike Works pricing, quick delivery and great customer service, whats not to like?
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.
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 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.
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.
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 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.
