Today I was riding my bike around the island and the chain is slipping badly. The fact that I ride it on the beach and it loads up with sand doesn't help, of course.
When I got home, I cranked up the Karcher Pressure washer and blasted the grease off the chain. I used a lot of degreaser and then washed it all off with Gel Gloss, which made it shine like new.
I then went online to see if I could find a new chain for it. The problem is, what kind of chain? What length, width, pitch, etc?
I looked at the chain that was on it, and it said "KAZ" and "H 8" but that was it. It was about 7.8 mm wide. The sprockets on the rear cassette are definitely worn - the trailing edge of each tooth is mashed slightly. It has had a hard life.
I looked for the owner's manual and receipt for the bike - and found it, strangely enough. I keep all that stuff in a big binder (appliance manuals, etc.) and it was in there.
Turns out it was a 1999 Trek, and cost me nearly $500 back in the day, 13 years ago. Since then, I have ridden it until the tires are nearly bald (I guess that will be next). The owner's manual is generic and worthless. How do I figure out what chain I should use?
Fortunately, BikePedia to the rescue. BikePedia has a listing of all bikes (or a lot of them) and what components they are built with. The data seems pretty accurate, although it doesn't list "RED" as an available color, and I an tell you for certain it was available in that color in 1999, as I have two of them.

I search online for a KAZ 900 chain and find the "Surplus Center" which has 125 in stock. Shipping costs more than the chain.
A quick trip to eBay and I find a chain breaker for $4 from China. So for $20 we are back in business.
Problem is, a new bike, similar to this one, can be had for about $200 these days. Spending 1/10th of the purchase price of a new bike to repair an old one is, well, questionable - particularly if it doesn't fix the chain skipping problem.
At least, since I am doing all the work myself, it will cost only $20. Over on Rich People's Island, they have one of these boutique bike stores. You know the kind, that sells bikes for twice what they are worth, and does things like fix a flat tire and charges you $50.
And I see people take bicycles there to get fixed - paying $100 for a "bike tuneup" or $50 to fix a flat - for a bicycle that might be worth $50 to $100 on a good day.
And that is the conundrum with cheap products from China. You can buy a decent consumer grade bike for $200 or so, that will last you a few years - and then you throw it away. Heck, you can buy a ride-able bike for as little as $100, if all you plan on doing is tooling around the neighborhood once in a while.
I'll put a new chain on the Trek and see where it goes. I am not sure I want to replace the rear cassette, as that would be just throwing more money at it. If the chain still skips under load, I may retire the old Trek and buy than 29" (!!) mountain bike I saw at Wal Mart the other day. $229 and take it home.
Or this monster 32" (!!!) beach bike they have for $199:
Note the standard 26" wheel for comparison. No one makes 32" tubes or tires yet, so if you get a flat, this truly is a disposable bike!
