1996 Eight Speed Cassette meets 2016 replacement

My dog walking mountain bike turns 20 this year, I bought it in May 1996 after my junior year of engineering undergrad.  It's now my most ridden bike because I use it to walk the dog several miles almost every day.

Shimano 11-28 cassettes, 1996 LX, 2016 Alivio

The new cassette might be lighter, it's drilled and the 2nd largest cog is riveted to the largest as a carrier with 3 arms removed

Worn and hooked teeth on old cassette, the 2nd/4th/5th largest cogs skipped the worst

The cassette teeth were already hooking when I replaced the chain 3 years ago, along with a skipping middle chainring and a new rear wheel because the original rim split.  When I put a new 3rd chain on last week, it skipped on at least 3 cogs, so the original cassette's done.

The new cassette's made in Indonesia, I've noticed that Japanese companies like Shimano, Canon, and Sony initially make their high end stuff in Japan, and later revisions and lower end stuff are eventually outsourced to Taiwan, China, Mexico, Singapore, Malaysia, etc.  Since the latest mountain bike cassettes are 11 speed, no more 8 speed cassettes are made in Japan.
 
Pirelli also moved Diablo Rosso II 110 front tire production from Germany to China, I noticed while changing tires on the ninja 250 and also on RC390's at the KTM demo.  The vibration from the single cylinder engine on the RC390 was ridiculous.

The rear rim split 3 years ago, it's the 2nd rear rim I've worn out this way

 The ninja 250 needed a new chain last year after 25k miles, and I realized I have accumulated a chain tool collection spanning 24 years.  A 1991 Cyclo Rivoli, a 1995 hyperglide compatible Cyclo Rivoli, a 2000 Crank Bros multitool, a 2004 Park folder, and now a 2015 Motion Pro PBR
