Review on JFOYH Cassette Mountain Bicycle Freewheel 46T by Jerry Estrada

I was pleasantly surprised at how well it worked on the first ride and performance improves over time. I had the lower stem transmission on my Giant Trance X with a Sram SX 12 speed cassette, derailleur and derailleur. One day the switch just fell apart in 2 parts. So I decided to upgrade the derailleur and shifter on GX 12s, but I couldn't upgrade the cassette without changing the hub. This cartridge solved that problem. Now I have a GX shifter, derailleur and this 11-52t cassette. The difference he had on steep climbs, I mean wow. The cassette is significantly lighter than the SX it replaced. If anyone is in the same boat trying to decide whether or not to invest in this I would say go for it, you won't be disappointed.
