## Description

Product Description               Accurate shifting, excellent wear resistance, and superior durability with 8 and 9 speed compatibility: the SRAM PowerChain II won't let you down.SRAMThere isn’t a company more dedicated to cycling than SRAM. You can see it in everything they do, from the crisp instant shift of their trigger shifters, or the way the chain glides smoothly and effortlessly across a cassette.SRAM chain engineers developed PowerLock as a tool free, sure and consistent way to connect to SRAM chains. While PowerLock does not require special tools for install, the especially tight tolerances of 10 Speed drive trains mandated that each PowerLock is for a one time only application.SRAM X-SYNC chain rings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain.Hardened Chrome - This type of chain is 4 times the elongation (wear) resistance to other chains. This is due to the new finishing process on the inner links and rollers. Push pin strength and ultimate strength are equivalent to our current chains. The chain lasts longer and is just as strong.                  Set Contains:               1 x Chain

## Questions & Answers

**Q: Will this chain work on a (old) 10-speed? Can I use a standard chain tool to pop out links for shortening?**
A: Depends on the condition of the freewheel.  If the gear teeth have not been rounded on the edges by extensive wear/usage then the chain will work.  If the teeth have been rounded it will skip some or all gears when you apply power through the cranks.  If that happens you will need to replace the freewheel as well.  Yes a standard chain tool will work to shorten the chain.  It's always a good idea to replace freewheel and chain together.  eBay is a good source for NOS freewheels for older 10-speeds.  NOS=new old stock.  Make sure you take measurements so you know what size/make freewheel will fit your bike.  The internet has many tutorials to show you how to do this.  Then your drivetrain will be good for 3,000-4,000 miles.

**Q: If I had to replace the casette, what casette would go with this chain? thx**
A: The 8 in the chain part number 870 is for 8 speed.  A 8 speed cassette is needed. A cassette with 8 gears.

**Q: What makes this different than the PC 850 SRAM chain?**
A: Differences between PC-850/870/890 are cosmetic, not "rust preventative".  PC-850 has all grey link-plates.  PC-890 has all nickel/silver plates.  PC-870 alternates nickel-outer & grey-inner plates.  Chains wear on the pins/bushing, not the plates.  Keep them clean and lubed for long life.

**Q: Will this fit an old 21 speed bike?**
A: Yes. I use this chain for all of my restorations. This chain works great for all the old road bikes from the 70's and 80's. If it has 5-7 sprockets in the back, this should work. It has the nickel plated links for the class factor. The PC-850 is the same chain without the flash.
