The rotation is smooth without excessive noise; the high-precision internal thread ensures a close connection with the bicycle hub and runs smoothly; it provides fast riding speed and reduces the amount of work required. Small size, easy to install on the bicycle.

Used as replacement on a Schwinn World Sport 12 speed. Several gears were partially broken on the old one and it skipped somewhat in shifting. Getting the old one off was the hardest part. When the new one was easily screwed on, and a new chain put on, no adjustment of the derailleurs was necessary to smoothly obtain all the gears. Works great.

Not even 50 km in the cassette/freewheel fell apart spilling all the bearings and rubbing my frame.

BESIDES POTENTIALLY DESTROYING YOUR REAR DERAILLEUR (SHIMANO), YOU MIGHT FIND IT VERY DIFFICULT TO REMOVE FROM THE REAR HUB. WOULD NOT RECOMMEND THIS COG

This freewheel fit perfectly and matched the spacings of my Shimano derailleur, however I could perceive a slight bit of rattle as it rotated but the bearing could be made no tighter. Overall it is an improvement over the Sun Tour it replaced.

My sprocket & chain were replaced at the same time back in January 2023. A couple days ago my rear 6-speed sprocket had been clicking while pedaling at medium to fast speed. Is this thing defective or not made to last for the daily rider?

Item looks to be of great quality. Spins nicely, nice profiles on teeth, edges finished nicely. Not cheaply made, I suspect this is one of Shimano’s subcontractors as this freewheel is very nice.
