   Dura Ace 7 speed compatible
   My old 1989 classic Schwinn Paramount build has nice Dura Ace 7401 7-speed shifting but you can’t get unused Dura Ace 7 speed obsolete cassette cogs and the 13-24 cassette was geared too high with my 52-42T Nuevo Record crank. A new 126mm rear wheel and this 14-28T freewheel shift perfectly with compatible 7 speed cog spacing and Uniglide shift ramps and lowered the gearing just as I wanted. I even exceeded the recommended 26T cog max and it still works great if the chain length is right. Nice smooth and fairly quiet pawl coasting noise. A Shimano-compatible Sunrace 7 speed 14-28T freewheel that I bought new at a bike shop for a quick fix shifted just as well but had a very slight wobble on coasting and had the small cog only a 1/4” from the dropout, so the genuine Shimano item seems a bit more precise. You’ll need a freewheel tool for removal. I also use the tool on installation because I make sure the freewheel turns on the hub threads smoothly clockwise and counterclockwise at the start to prevent cross-threading and trashing the hub threads (a big pitfall for home mechanics not familiar with old style freewheels).

   High Quality Replacement Freewheel
   I have a pretty inexpensive bike, bought from a big box store, and recently started having some issues with the drivetrain. First the chain failed. Replaced that, then on my next significant ride, the freewheel literally came apart and dropped the tiny bearings on the road about 5 miles from home. Once I got that apart to see what parts I needed, I found that the wheel bearings were pretty rough. Probably all of this started with trying to overcome the failing wheel bearings, but now I have this sweet new freewheel and it now pedals and shifts so smoothly. This freewheel is a little different from what I’m used to, it doesn’t make any noise when coasting or back-pedaling, but it still locks in tight, and never jumps a tooth. Only have about 60 miles on it so far, but I’m happy with the purchase.

   Perfect fit for my Walmart Hyper Spinfit 700c
   I had to replace my freewheel after the original fell apart. I found it was cheaper to replace it than try to repair the old one. I’d never replaced one before, but with the help of YouTube and a freewheel lock ring removal tool (NOT the cassette tool; mandatory but inexpensive) I was able to get the old freewheel off the hub and install this new one without too much trouble (and all for less than $30). Clicks in reverse and operates exactly as it should. Very pleased for now, time will tell if it holds up.

   Used this to replace a Sunrace set on an older Raleigh, and it fits and works fine. But don’t try to cheap out like I did and try to re-use the chain. Even though the bike has fairly few miles on it and there was no visible wear on the old gears, there was very noticeable noise under load with the new sprockets until I did replace the chain. Works great now!

    Ho installato la Shimano MF-TZ500 sulla mia bici e ne sono rimasto davvero soddisfatto. • Qualità costruttiva:La Shimano MF-TZ500 è realizzata con materiali solidi e resistenti, garantendo una lunga durata anche con un uso intensivo. I denti delle corone sono ben lavorati, assicurando un ingranaggio fluido con la catena. • Prestazioni:Il cambio tra le marce è fluido e preciso, senza esitazioni o salti. Testata su percorsi asfaltati e sterrati, offre ottime prestazioni in entrambe le condizioni. La gamma di rapporti è ideale per una bici versatile, perfetta sia per pedalate in pianura che per affrontare salite. • Facilità di installazione:Compatibile con la maggior parte delle biciclette a ruota libera a 7 velocità, l’installazione è stata semplice. Con un attrezzo per la rimozione della ruota libera, il montaggio è stato completato in pochi minuti. • Rapporto qualità-prezzo:Ottimo investimento per chi cerca affidabilità e prestazioni senza spendere troppo. È difficile trovare un prodotto altrettanto valido nella stessa fascia di prezzo. • Conclusione:La Shimano MF-TZ500 è un’opzione eccellente per chi vuole migliorare la propria bicicletta o sostituire una ruota libera usurata. È performante, durevole e facile da installare, rendendola un acquisto che consiglio vivamente.
