Great value
5000 + miles. Its on ebike but I pedal most of the time and go thru the gears. The chrome is still in good condition, no rust. 3yrs and 5 chains latter. Do I need to say it works great? It is geared lower and slightly higher than standard 7 speed.

e-bike conversion
Installed on touring bike with original Shimano 105 9x3 drivetrain (brifters). E-bike conversion required use of freewheel in place of original 9-speed cassette. I found that I needed to add spacers to provide adequate standoff between dropout and wheel bearing. I was able to modify (drill out) two standard hardware store steel washers to provide the correct spacing. Freewheel functions flawlessly with original drivetrain components. "Drillium" style and chrome plating provide a nice appearance as well.

Perfect fit
I had to replace the freewheel on my ebike. This freewheel has one higher and one lower geared sprocket than my original. It’s awesome climbing on mountain trails and quite a lot of improvement at higher speeds

I can't believe it is still alive
Every freewheel I bought before this would die after about 6 months, or instantly if I pushed hard up a steep hill in a low gear (hills around hear go up to a 25% grade). When I bought this, I expected the same, so I even bought the 2-year warranty. Despite my best efforts, I cannot kill this thing - I am thoroughly impressed!

A great way to get some extra gears on older freewheels
So I converted my sons bike over to 3x9 brifters. Outside of having to change to a larger cage rear derailleur, and a 3x front, wasn't much else to do. Freewheel went on as advertised.

Warped out of the box. Very poor quality
Installed this and put the wheel on the bike. One spin on the chain and it was obvious the freewheel was badly warped. So much so that it would jump gears from the wobble in the low gear. Very disappointed. I will give two stars because the freewheel felt very smooth. Seems to be well greased. Just has warped gears. Sent back for refund

Could never get this to work properly with my shimano Altus 9 speed
I used this on an ebike wheel that didn't have a cassette. could never get it to shift correctly. Had problems with jumping gears. Changed shifter to 7 speeds and used a megarange freewheel instead.

Works well
Seems like a well made item, works well, fitted to a Yose Power freewheel hub that I ordered in error, only real let down was the cereal bar box it came packaged in, as that made it feel like I had ordered some second hand parts from eBay
