Doesn't matter what it is, I'm always happy buying bike stuff. Last couple of days, a small Camelback valve bottle for Gina's compact seat tube cage. PC51 chain and online HG50 cassette 12/25 (from Loosespokes, Hilbasher sale spotter).
Nice thing about online orders, you get a cute little box and a newspaper to read on the throne ha ha!
I figured I'd try the HG50 cassette after having good luck with the Sram equiv. Only $33 can't go wrong.
I track my miles so I know for a fact that I got 14,000+ miles out of my last combo. I replace the chain and cassette together. I can't figure out why people replace their chains every 2-3000 miles. I keep them clean and lubed. I do have to say the last couple months my chain was noisy. I knew it needed replacement but some rain and low mileage months so I just didn't get around to it. I logged 15,000 miles but subtracted 1000 for the noisy months.
My buddy replaces his Dura Ace chain every 2500 miles and the Dura Cassette every third chain!.....that's a lot of money and to be honest, my bikes run smoother and more quiet. IMO, it's all tuning and keeping it lubed.
I did read some reviews on teh PC51 as it's the chain I have been using. Just about every review on one site said the thing broke like 3 times in two weeks. I don't understand it, I've been using them for years and I always get a good 14 thou. I read lots of stories of big strong legs and snapping chains. I guess I'm just a weak little wuss with skinny legs.
So here is my cheap cassette and cheap chain.

Always amazes me, the wheel was spinning full bore but the cam picks it up like it was standing still.
