Light weight
Great cassette light weight and crisp shifting hoping it will do well on my ebike conversion using a middrive motor. It's been running well and problems. Time will tell how long it lasts

Easy to fit
Great product, as described. Was surprisingly easy to fit. I would suggest you view a few videos on YouTube if you are not sure how to fit it. Fits perfectly on my MTB, didn't even have to adjust the derailleur. Feels a lot smoother than the previous one.

Good replacement.
My new replacement chain was still slipping so then replaced the cassette with this one. No more chain slipage and now nice and quiet.

Fitted nicely on the FH-M475 freehub. Even fitted as a replacement for my 7-speed previous freewheel.

Tänk på att center bussning måste demonteras. Denna kassett är toppen och växlarna funkar fint igen.

Prompt shipping, arrived 1 day early. Packed well to eliminate shipping damage. It was an exact replacement for my Shimano cassette on my Trek Shift 4. Also purchased the Park Tool FR-5.2 Cassette Lockring Tool needed to remove and install the cassette from the hub and a new Shimano chain. Tip: I didn't have a chainwhip tool to hold the cassette when using the removal tool. I wrapped the old chain around the cassette and clamped the chain in my bench vise. Worked great. The new cassette and chain works perfectly! No jumping/banging when peddling hard in high gear.

El paquete llegó muy rápido, antes de la fecha estimada. El cassette funciona muy bien, lo instale en un smart trainer y lleva dos semanas de uso sin problema alguno. El precio es muy competitivo, más barato que en Amazon USA
