Learn more about chain sizes.
There are two main chain sizes, 1/2 x 3/32 and 1/2 x 1/8. The 1/2 refers to the distance from pin to pin. The 3/32 and 1/8 refer to the width of the space between the inside sideplates. 1/2 x 3/32 chains are referred to as "derailleur chains" because they're narrow chains for use with bicycles with derailleur gearing. Note: When buying this type of chain be sure to get the one made for the number of cogs on your rear wheel, such as 8-, 9- or 10-speed. The other size chains, 1/2 x 1/8 are referred to as "coaster-brake" or "BMX chains" because they're wider, and for use with coaster-brake, BMX and certain 3-speed drivetrains. If you have any questions about chain compatibility, please contact us.

The SRAM PC-991 Hollowpin chain is the best chain I've ever owned. I switched from Shimano Dura-Ace and Ultegra chains because you have to replace the chain pin with a new one everytime you remove the chain. By the way, for all those thinking it's best to just leave the chain on the bike while you clean it - that's not the best way. The Sram powerlink allows easy removal of the chain for cleaning.(which the best thing to do) It can be done with a snap and requires no tools! You get a cleaner chain, cassette, and chainrings with NO scratches on the frame because the chain got in the way while cleaning your gears. It has never rusted and it always allows smooth, quick shifts.
