Great replacement
Replaced an OEM for a 6KU flip-flop which had broken and was skidding. Huge positive difference--smoother and quieter with barely any vibrations at all. Great value for the price!

Good quality
Works well. No complaints. It looks cool with a nickel plated chain on a black frame.

For the Price, Fills the Need
Good quality freewheel that is easy to install and seems to work perfectly. Why drop a star? Definitely not a quiet freewheel and neighborhood dogs can hear me coming from a block away. However, it is smooth and has no grinding to worry about.

Fits and a little more heavier duty than stock freewheel that always strips out
Fits for a razor sx 500/mx650 but to put the stock 80tooth gear on you have to grind the inside of it to fit over the acs freewheel. Spent about 20 minutes doing it with a drill bit attachment for metal. I will update if it strips out. Almost been a year and it is still holding up so I bought more for the other modded razors.

Nice freewheel for the price
Feels better and smoother than a 10 dollar freewheel and for the price it looks like it competes with more expensive freewheels time will tell

I've used quite a few freewheels by different makers, some cheap some very expensive. This one seems to have hit a sweet spot! Very strong, quiet, even though I ride hard and over 500km/month
