Replacing parts
#1
Something got caught in my chain, I think near the rear derailleur. Anyways, the rear derailleur is broken and I need to replace it, the chain too. Its a Walmart bike so i'm not sure what I should do for finding the measurements, but I do know its this. Its generally a really cheap bike so I want to find some new parts, or part specifications that are compatible. I thinks the gears are a 9x3 with twist shifts. If there's anything that could help performance like changing the cassette or chain rings, that would be helpful, but for now I need help finding a rear and most likely a front derailleur that is compatible. I know that bike chains and cassettes can have different spacing, and derailleurs can have different pull ratios, but I don't trust myself with this. Any help would be appreciated!

I'm also looking for a rear shock and a fork, I need to go with an air shock so I can adjust it, i'm too light for my shocks to take effect right now

Update: One of the twist shifts kinda popped out, and I definitely need a front derailleur.

Suggest browsing through Walmart parts and find replacements like yours.

10-4 to that PK repair parts and suspension changes will cost more than getting a more suitable bike.

It amazes me that these bikes can be shipped from China and sold for under $100 and still a profit is made. The good is that many people can afford bicycles and get into the sport eventually upgrading.

IMO fix whats broken and enjoy , or start thinking about the next bike. Do the math.
