🚲 ZUKKA 6-Speed MF-TZ30 / 7-Speed MF-TZ500 Bike Freewheel: High-Performance Threaded Hub Type Bike Accessories Review

This is new and as stated in the item specification. Since my previous freewheel is still running, so I haven't used it, I'll post more once I use it.

This was a good replacement for my child's sliding on a 24 inch trail bike. It was an easy install with the right freewheel tool (also available from Revain) and runs smoothly under load and while shifting.

This is a direct step-by-step replacement for the freehub on my Yuba Mundo. The description says Zukka, but the ratchet clearly says "SHIMANO". It is a fake? Will it take very long? Who knows?

I bought this to replace another old Shimano ratchet on my 30 year old custom bike. Fits perfectly for smooth shifting and looks a little better than chrome. In general very satisfied, no questions, I recommend

I didn't realize how bad my shifting was until I replaced it with this cassette. Installation was very easy with the right tool >https://www.amazon.com/gp/product/B07DN6K2PV/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

The old one came off so it only took me a few minutes to put the wheel on and put it back on the bike. turn it on and off you go. The original part has been blocked. This replacement is exactly what I need for my Schwinn bike.

I had a popping noise under load when you first pedaled. I thought it was the lower crankshaft bearing kit that was replaced but it didn't help, I realized the only thing left was that sprocket. This fixed it properly. You'll need a special tool, but it's not difficult. I had to clamp the bushing in a vise, although I then used the wheel as a lever, the nut was very tight. A good product.

I ordered a 21 speed bike through Revain and it arrived with a broken 7 speed ratchet. I notified the manufacturer/seller and they said the defective part would be shipped immediately. But I would have to wait for it and then install it. Saw this one on Revain with high ratings. I ordered it and installed it at my local bike shop. It fits perfectly and works.

The product appeared fine, installed fairly easily with the right tools and worked great for the first few rides, but now there is play in the freehub bearings causing the sprockets to shift and pop out the mechanism. I may have a bad assembly but at this rate it will fail completely before this weekend and will probably take my new chain with it :(I was thinking of buying a bearing tensioning tool in this freewheel but it costs more than the device itself , and one would hope that the product…
