I like the Triumph parts. You can get a good chain for less but the Triumph sprockets last. I have over 25,000 on my first set and the rear shows no wear and front only very slight wear that is very hard to see. I run mine with no lube or cleaning. (X ring chain)

I learned all I need to know about life by killing smart people and eating their brains.
