Repairing mongoose dxr al 21 bikes

https://www.mongoose.com/

Hey, Local bike shop determined that both wheels were defective. I took the junk back to Walmart and got a refund... PROBLEM SOLVED!!

Check out https://gearly.org/ for more info.

Thanks.

The crankset and pedals on that bike or any other are not unique to one model. Either the original or compatible replacements are available at a variety of sources, but there are several dimensions that are important. Best to go to a bike shop or bike co-op to get info on what is needed and available.

I’m happy to help further over the phone at https://www.6ya.com/expert/donald_f2ed37026a3ac881

They don't sell to the general public. Go to the store where you bought it and ask to order from them.

For any low end Pacific Products you only going to find minimal information like this:

Most parts are interchangeable if you need to repair your bicycle (since most components are made by other manufactures like Shimano). What are you trying to accomplish.

Or it could be the dreaded mismatch of new chain with worn drivetrain parts...
