Default Re: Thing to do / know before getting a Jack Shaft

I guess you have to look at the overall quality and type of bike. Wally World bikes typically use plastic as much as possible in their derailleurs, bottom brackets and rear hubs/freewheel.

After all- they are designed for 1/2 horsepower max (human power) and most engines are putting out around 3 horsepower.....that's 6 times what is designed for, even good bike components won't take that abuse forever.
If some's good...more is better and too much ain't enough.
