Shimano Sf-Mx30 Dx Single Freewheel, 16T x 3/32", Single, Black

If you ride single speed road bikes and don't want the loud whir found on most freewheel sprockets, this is what you want.If you rely on this "angry hornets nest" noise to make yourself noticeable to pedestrians or the like, this is not what you want.This Freewheel Sprocket is about as silent as possible. Engagement is great and it's been running smooth so far. I will update this review when I've put at least a thousand miles on it (which will likely be 3-4 months of riding.)

Purchased a refurbished freewheel. Very easy to install, no need for special tools. All you need is your bike and your chain. I was surprised as to how quiet it was while coasting.

Amazing purchase. Fits perfectly well with my GT Vertigo BMX

Too expensive but silent like a ninja. Has less wobble than cheaper products.

I needed it anyway. Thank you

I've had this on my single speed road bike for a few months now and it has run smoothly.I don't have a ton of experience with other freewheels but this one seems to be well made. I have put several hundred miles on it and have had no problems. It runs smooth and quiet.

Perfect freewheel! Love the all black too, only one I could find.

Did not work coming out of the box because the pawls were stuck open, so it freewheeled both directions. Took it apart and cleaned out the stiff grease, reassembled and now it works fine. Shouldn't have to do that.
