Perfect replacement for my 1987 Schwinn Predator Free Form EX
Headline says it all, this is a perfect factory replacement for my old school BMX. Old one still spun but was crunchy while pedaling. Drivetrain is nice and quiet now. I knew it had to be the freewheel as I had just redone all the bearings in the bike front to back and replaced the chain. The only way I can see someone being dissatisfied with this part is if they ordered it unnecessarily. Might grab an extra for the parts bin.

Mine had no defects? Easy to install, needed to buy tool to install. Also around same price, I put them on Skyway Tuff 2. I have on an old school late 80’s Haro bike. Made bike look good, sound good, I would recommend this part.

Good replacement freewheel hub.
W**!
so-so, quality.
It looks shiny chrome. And then when you look closer, it looks like its coated with aluminum foil. I'm surprised its not made of plastic underneath the foil. Buuut,, you get what you pay for!
